Adenophlegmon: causes of the disease, main symptoms, treatment and prevention

Adenophlegmon

Adenophlegmon is an acute purulent inflammation of the subcutaneous fatty tissue of an abscessing nature, closely associated with purulent processes in the regional lymph nodes (lymphadenitis). Adenophlegmon accounts for more than 21% of all maxillofacial pathologies; other localizations are much less common. The pathological process develops more often in children, is not gender specific, and is non-endemic. It is worth noting that scientists belonging to the domestic school of dermatology played a major role in the study of adenophlegmon. A. Abrikosov gave a coherent theory of the occurrence of adenophlegmon in 1938, and I. Rufanov supplemented and developed the theory of the pathogenesis of the disease in 1960. The relevance of this issue at the present stage is due to the severity of the purulent process, which affects newborns and preschool children and poses a real threat to their lives due to the development of septic complications. In adult patients, adenophlegmon can cause the development of sepsis and osteomyelitis.

Forecast

If you seek help from a doctor in a timely manner and complete the full course of treatment, the prognosis for APO is favorable. The use of antibacterial drugs in the initial stages of pathology can prevent the acute form of an abscess and reduce the risk of further complications.

So, adenophlegmon is an infectious-inflammatory process in fatty tissue, localized in close proximity to the lymph nodes. The favorite places for the tumor to be affected are the area under the lower jaw, near the ears, in the groin, and on the neck.

Treatment of the pathology is exclusively surgical, followed by drug correction of the general condition. With timely medical care, the prognosis for this disease is favorable; otherwise, adenophlegmon can provoke sepsis.

Causes of adenophlegmon

Purulent inflammation of the subcutaneous fat, like any other purulent inflammation, has a clear cause. This is an external or internal infection, most often with coccal flora. As a result of a decrease in the body’s defenses of an exogenous-endogenous nature (focal and perifocal infection, especially in the area of ​​the tonsils, oral cavity, kidneys, previous illness, skin trauma, more often post-injection, pyococcal damage to the dermis), the anti-infective barrier of the lymph nodes decreases.

Typically, lymph nodes and lymphatic vessels, together with the venous system, ensure the natural outflow of fluid from tissues and organs. During inflammation, this plays a decisive role, since in the early stages of development of the process, lymph flow slows down, vascular permeability increases, conditions are created for the accumulation of microbes in the lymph nodes, where pathogenic flora is absorbed by the cells of the reticuloendothelial system, the remnants of microorganisms are broken down, and released into the circulatory system, where they die under the influence of antibacterial therapy. If inflammation increases, the lymphatic vessels thrombose, blocking the outflow, blocking the spread of the inflammatory process. Against this background, microbes from the lymph nodes leak into nearby tissues, causing inflammation in them and forming adenophlegmon.

Classification of adenophlegmon

Adenophlegmons are usually distinguished by the localization of the inflammatory process. The most significant in terms of severity and possible consequences:

• adenophlegmon of the lower jaw and chin is the most common option;
• adenophlegmon of the neck - a consequence of violations of personal hygiene of the oral cavity, auricle, and scalp;
• adenophlegmon of the groin area - the result of hypothermia;
• adenophlegmon of the axillary region - a consequence of infection of skin microtraumas;
• adenophlegmon of the parotid region is a septic complication.

Causes of the problem

The etiology of this disease is very simple. After any infectious-inflammatory pathology (often lymphadenitis leads to APO), an immune failure occurs in the body, and the lymphatic system loses its full protective properties.

Lymph nodes become inflamed, swollen, and stop resisting pathogenic microflora, which massively attacks the body with reduced immune function. Bacteria settle in the lymph nodes, seep through their walls, enter the adipose tissue and cause an acute inflammatory process in it.

The following factors can also be “provocateurs” of APO in children and adult patients:

• soft tissue injuries of the neck;
• past infectious and inflammatory diseases;
• dental problems;
• inflammation of the lymphoid apparatus of the pharyngeal ring;
• jaw cysts;
• infection during medical procedures;
• malignant neoplasms;
• various pathologies of the excretory (genitourinary) system.

Symptoms of adenophlegmon

Clinical manifestations of adenophlegmon are divided into general, characteristic of all varieties, and local, characterizing exclusively one or another form. General symptoms include a temperature reaction, a feeling of weakness, fatigue, lethargy, increasing signs of intoxication of the body, exacerbation of chronic foci of infection. Against this background, a tumor appears located next to the regional lymph nodes. It is dense to the touch, fluctuating in the center, painful on palpation. With further progression of the process, the tumor abscesses, opens, or septic dissemination of the process occurs. Often such a tumor forms at the injection site.

Symptoms corresponding to the type of adenophlegmon depend on the location of the process and have characteristics. Adenophlegmon of the submandibular region is preceded by dental intervention (for example, removal of a wisdom tooth), regional lymphadenitis. When adenophlegmon forms, pain is observed when swallowing, opening the mouth, and speech is impaired. Adenophlegmon of the neck is formed against the background of a general decrease in immunity, which leads to the activation and proliferation of pathogenic microbes that latently exist on the skin of the scalp and in the oral cavity, especially with errors in hygiene. The trigger for the development of the disease is the accumulation of a critical amount of bacteria, which transforms the latent process into the development of a focus of coccal infection.

The development of adenophlegmons in the groin is a consequence of an inattentive, irresponsible attitude towards one’s health. They arise as a result of periodic prolonged hypothermia, causing urethritis, cystitis, and inflammation of the pelvic organs. The resulting infection is so resistant to the therapy that inflammation occurs and abscess formation of the inguinal lymph nodes occurs. The outcome is often infertility.

How does APO manifest itself?

Adenophlegmon manifests itself with rapidly increasing signs of general intoxication of the body. Further on the neck, in the area where the submandibular lymph nodes are located, a tumor appears and is actively growing. This formation is painful on palpation and has a characteristic hyperemic focus in the center. Adenophlegmon is dense, this indicates the presence of fluid in its cavity (fluctuation). There are multiple small hemorrhages on the skin and mucous membranes located in close proximity to the tumor.

Untreated dental diseases are a common cause of APO

If adenophlegmon develops in children, they become tearful, weak, apathetic, refuse food and active games, and there is increased sweating. Against the background of APO, other diseases worsen in the child - diathesis, dermatitis, ARVI, etc. Sometimes adenophlegmon causes hyperthermia, the abscess can resolve outward (through the skin).

Diagnosis and treatment of adenophlegmon

The clinical picture and anamnesis of the disease are typical. Additionally, ultrasound of soft tissues and x-ray diagnostics are used to exclude osteomyelitis, tumors, and cysts. OBC, OAM, blood biochemistry, blood test for sterility are required. To prescribe etiopathogenetic therapy, culture of punctate purulent lesions on nutrient media is used, followed by determination of sensitivity to the antibiotic. Purulent inflammation is differentiated from phlegmon (choice of surgical intervention), tuberculosis, actinomycosis, osteomyelitis, periadenitis, inflammatory infiltrate, osteophlegmon. Purulent surgeons treat pathology.

Treatment of the disease is complex. The severity of the process dictates the need for urgent surgical intervention in a hospital setting. The phlegmon is opened and drained. The wound is treated in an open manner with washing, administration of antibiotics and enzymes, and dressings. Postoperative antibacterial, anti-inflammatory, and detoxification therapy is mandatory. They include means for general strengthening of the body (vitamin therapy) and increasing immunity (immunostimulants, immunomodulators). It is necessary to sanitize all foci of chronic infection. Prevention consists of timely diagnosis and treatment of chronic infections and strengthening the immune system. The prognosis with timely diagnosis and treatment is favorable.

Diagnostics

An appropriate diagnosis is made by a specialist based on a visual examination, anamnesis and clinical studies. Treatment of adenophlegmon is carried out exclusively in a hospital setting under the supervision of a doctor. Adenophlegmon of the neck is a dense, hyperemic, inflamed formation (tumor), painful on palpation.

A patient who comes to the doctor for a consultation voices classic complaints of general malaise, weakness, and swelling under the lower jaw. Subsequently, doctors usually discover that there were symptoms of lymphadenitis (a dense ball of varying sizes is present in the area of ​​the lymph nodes). The doctor notes the presence of infiltration, swelling, hyperemia and other signs of APO that are accessible to visual inspection and palpation.

Important! If the lower submandibular triangle is affected by a purulent-inflammatory process, patients experience dysphagia (difficulty swallowing), problems with speech, and discomfort when opening and closing the mouth.

Adenophlegmon, localized in the submandibular region, is the most common type of this disease

Laboratory studies demonstrate an increase in ESR (indicating the presence of acute inflammation in the body), an increase in the number of neutrophils and leukocytes. It happens that APO develops within a few weeks after the patient undergoes dental treatment.

The doctor has no complaints about the condition of the teeth and gums, but under the lower jaw, a small ball appears at first, and then increases in size, a dense ball, which is also painful on palpation. Often such patients are referred to an otolaryngologist, but he also does not find any respiratory abnormalities. The cause of the pathological process and pain syndrome in this case is the same adenophlegmon under the lower jaw.

Pathogenesis of Adenophlegmon:

The occurrence of adenophlegmon is a manifestation of the failure of the barrier-fixing function of the lymph node, in which filtration of lymph occurs, retention of microorganisms by reticuloendothelial cells and their phagocytosis with the transfer of information about their antigenic structure to the immunocompetent organs. When the outflow pathways from an inflamed lymph node are blocked, microorganisms and their metabolic products of an antigenic nature can penetrate through the lining of the lymph node into the surrounding tissue, causing inflammation in it. Clinical picture. From the anamnesis it is often possible to find out that the onset of the disease was preceded by trauma, inflammatory processes of the scalp, mucous membrane of the oral cavity, nose, and tonsils. Then, in the suprahyoid region, in the neck area, a moving, painful “ball” with clear contours appeared. As the “ball” grew larger, it lost its clear contours, and signs of the body’s general reaction such as headache, general malaise, and increased body temperature became more pronounced. Complaints and objective examination data, reflecting the local picture of the inflammatory process, depend on the localization of adenophlegmon. With a similar localization and prevalence of the infectious-inflammatory process, the disturbance of the general condition and the severity of the general reactions of the body in patients with adenophlegmon are usually less than in patients with phlegmon. The possible complications are the same as in patients with phlegmon: progressive spread of the infectious-inflammatory process to adjacent anatomical areas, spaces and vital organs (brain, its membranes, mediastinum), generalization of infection - development of sepsis, increasing cardiopulmonary, renal , liver failure as a result of infectious-toxic damage to these vital organs and systems.

Tonsillogenic phlegmon of the neck, complicated by mediastinitis, in a patient with diabetes mellitus

Tonsillogenic phlegmon of the neck against the background of diabetes mellitus (DM) is extremely difficult, often complicated by the spread of a purulent process into the mediastinum and the development of multiple organ failure, which in 10–15% of cases leads to death. In such patients, the purulent process is prone to lightning spread. Decompensation of diabetes worsens the patient's condition. 1 ml of pus inactivates 10–15 ml of endogenous or exogenous insulin, thereby aggravating metabolic disorders [1–3].

We present an observation of tonsillogenic phlegmon of the neck, complicated against the background of diabetes by purulent mediastinitis, pleural empyema and multiple organ failure, which was the cause of death.

Patient M., born in 1948, was admitted to the ENT department of the State Budgetary Healthcare Institution MONIKI named after. M.F. Vladimirsky" with complaints of difficulty breathing, pain in the neck, worsening when turning the head, swelling in the submandibular region on the right, sore throat when swallowing, thirst, weakness, increased body temperature, headache.

From the anamnesis it is known that 5 days before admission to the hospital there were complaints of a sore throat and difficulty passing liquid and solid food after hypothermia (the patient worked outside, drank cold water). She did not seek medical help, she treated herself: she drank hot milk. After 2 days, difficulty breathing appeared during physical activity, and an infiltrate in the submandibular region also began to gradually increase. During the illness, she did not notice any increase in body temperature. She did not sleep the entire night before hospitalization due to difficulty breathing. For the last 3 days I drank only water. I contacted an ENT doctor at a local clinic, who diagnosed: peritonsillar abscess, neck phlegmon, 2nd degree laryngeal stenosis. The patient was urgently sent to the ENT department of the State Budgetary Healthcare Institution MONIKI named after. M.F. Vladimirsky". It is known that the patient has been suffering from hypertension in recent years with an increase in blood pressure to 180/110 mm Hg. Art. and type 2 diabetes, for which she took glibenclamide 5 mg, 0.5 tablets 2 times a day. Blood sugar levels were not measured.

Condition on admission: extremely severe, body temperature – 37.5oC. The patient is conscious, forced position - sitting. Hypersthenic physique, increased nutrition. The skin is pale, there are no rashes. Breathing at rest is noisy, with the participation of auxiliary muscles, respiratory rate is 26–30/min. The chest is symmetrically involved in the act of breathing; in the lungs, breathing is harsh and is carried out in all parts of the lungs. Heart sounds are rhythmic, muffled, heart rate - 110/min. Blood pressure – 157/95 mm Hg. Art. The abdomen is soft, the liver is at the edge of the costal arch, physiological functions are normal. No meningeal symptoms were detected at the time of examination.

During mesopharyngoscopy: grade II–III trismus, asymmetry of the soft palate due to edema and infiltration of the right palatine arch are determined; at the upper pole of the right palatine tonsil there is a point fistula with copious purulent discharge. There is a dense infiltrate in the right submandibular region, which extends to the anterolateral surface of the neck, the skin over it is hyperemic. The laryngeal mass is not changed. Moore's sign is positive.

Fibropharyngolaryngoscopy: the mucous membrane of the pharynx and larynx is sharply hyperemic and swollen. A bulging of the lateral wall of the oropharynx is detected, the laryngeal mass is shifted to the left due to infiltration. The mucous membrane of the epiglottis is sharply hyperemic and infiltrated.

The patient was consulted by an endocrinologist, cardiologist, maxillofacial surgeon, and ophthalmologist.

After administration of 10 units of soluble insulin subcutaneously, glycemia was 33.4 mmol/l. The insulin dose was calculated. Blood test dated 04/11/2007: hemoglobin – 175 g/l, glucose – 31.2 mmol/l, total protein – 82.7 g/l, creatinine – 240 µmol/l, leukocytes – 21,109/l, ESR – 51 mm/h

Electrocardiogram (ECG): sinus tachycardia. Rare ventricular extrasystole. Horizontal direction of the electrical axis of the heart. Low-voltage ECG in standard leads. Rotation of the heart clockwise, i.e. with the right ventricle forward. Pronounced changes in the myocardium of the left ventricle.

On a chest x-ray, the lung fields are transparent. Roots are structural. The diaphragm is positioned normally. Heart with an enlarged left ventricle. The aorta is compacted. The mediastinal shadow is not expanded. Free gas and liquid are not detected.

An X-ray of the neck according to Zemtsov shows thickening of the prevertebral soft tissues due to infiltration with a maximum at the level of C5.

Taking into account complaints, anamnesis, clinical picture, and examination, a diagnosis was made: right-sided paratonsillar abscess; phlegmon of the neck; II degree laryngeal stenosis; Type 2 diabetes of moderate severity, decompensated; suspected ketoacidosis; stage II hypertension; III degree obesity.

After 3-hour preoperative preparation (antibacterial, detoxification therapy, correction of blood sugar levels - surgical level 12.9 mmol/l), surgical intervention was performed - tracheostomy under local infiltration anesthesia, then under anesthesia through a tracheostomy, abscessonsillectomy on the right, opening and drainage of the cellular spaces of the neck on right. Surgical findings: soft tissues have the appearance of “boiled meat” with a pungent putrefactive odor, their differentiation is difficult. A passage into the posterior mediastinum was detected about 4 cm below the jugular notch. There is no pus, but gas with a putrid odor is obtained. An inspection of the submandibular area and peripharyngeal space was carried out; purulent discharge was also obtained. A smear was taken for microflora and sensitivity to antibiotics. 3 double-lumen drains were installed in the posterior mediastinum, peripharyngeal space, and submandibular region (Fig. 1).

After the operation, the patient was transferred to the intensive care unit, where massive systemic antibacterial therapy was carried out according to the principle of de-escalation - meropenem 1 g 2 times a day IV + metronidazole 100.0 3 times a day IV, infusion therapy in a volume of 2900 ml , decongestant therapy, vascular therapy, correction of blood sugar levels (insulin 40 units). Daily dressings were performed and active flow aspiration was established.

Blood sugar levels ranged from 13.4 to 18.1 mmol/L. In a biochemical blood test dated April 13, 2007: total protein - 48 g/l (normal - 64-83), urea - 61.1 mmol/l (normal - 1.7-8.3), creatinine - 700 µmol/l (normal – 44–80), creatinine kinase – 782 units/l (normal – 24–170), lactate dehydrogenase – 1050 units/l (normal – 230–460), C-reactive protein – 215 mg/l (normal – <5), uric acid – 1232 µmol/l (normal – 142–339).

X-ray of the chest organs in dynamics 1 day after the operation: negative dynamics are noted, manifested in the form of total inhomogeneous darkening of the left pulmonary field; infiltration of the pulmonary field cannot be excluded. The mediastinal shadow is expanded. Free gas is determined. There is also a moderate widening of the mediastinum.

Together with thoracic surgeons, an inspection of the cellular spaces of the neck on the right and thoracoscopy were performed, during which a turbid liquid with a foul odor was obtained. A right thoracotomy was performed. In the right pleural cavity there is about 200 ml of liquid the color of meat slop with an ichorous odor and fibrin flakes. Inspection and drainage of the right pleural cavity, anterior and posterosuperior mediastinum were performed. In the postoperative period, previously administered therapy was continued. The patient was consulted by a detoxicologist, and plasmapheresis was recommended. 1 day after the operation, a dynamic X-ray of the chest organs was taken: there was no gas in the pleural cavities, the mediastinum was moderately dilated, and there was a small amount of fluid in the pleural cavities. The median shadow is expanded at the level of the aortic arch.

Despite the measures taken - detoxification, antibacterial therapy, correction of blood sugar levels, 2 sessions of plasmapheresis - the patient's condition continued to progressively deteriorate. The patient was on artificial ventilation through a tracheostomy, unconscious, hemodynamics were supported by adrenergic agonists, and complete compensation of diabetes could not be achieved.

Against the background of progressive cardiovascular failure, cardiac arrest was recorded on the 4th day after admission to the hospital. Resuscitation measures for 40 minutes - without effect. The patient died. An autopsy confirmed the diagnosis and revealed pronounced dystrophic changes in parenchymal organs. The cause of death was multiple organ failure.

Thus, clinical observation shows that the occurrence and progressive course of neck phlegmon with the development of such severe complications as mediastinitis, sepsis are directly dependent on concomitant diseases of the body; their course worsens sharply against the background of diabetes.

Symptoms of Adenophlegmon:

Sick children are characterized by adynamism, lethargy, lack of contact, severe weakness and sweating. In approximately a third of children with facial phlegmon, concomitant diseases are diagnosed: ARVI, bronchitis, pneumonia, acute otitis media, exudative diathesis, etc. The source of infection can be teeth, ENT organs, traumatic injuries, including post-injection injuries, due to violation of aseptic rules . The clinical picture of the disease in these patients is characterized by rapidly increasing symptoms of intoxication and the severity of local changes: the presence of diffuse swelling in one or several anatomical areas with pronounced hyperemia in the center. The swelling is painful, has a dense consistency with signs of fluctuation. Multiple pinpoint hemorrhages are observed on the skin and mucous membrane of the vestibule of the oral cavity, tending to merge in the skin area.

Diagnosis of Adenophlegmon:

Differential diagnosis is carried out with phlegmon in osteomyelitis (osteophlegmon), periadenitis, inflammatory infiltrate. The difficulty in making a diagnosis arises in the early stages of the process, when one nosological form (for example, periadenitis) in its dynamic development, in the absence of treatment, passes into another. The main thing in this case is to correctly determine the nature of the inflammation - purulent or non-purulent. Differential diagnosis with osteophlegmon is also extremely important, since the methods of surgical care for these types of phlegmon are different.

Treatment of Adenophlegmon:

Treatment of patients with adenophlegmons is based on the principles of emergency care. It is advisable to perform surgical interventions in all children under general anesthesia. If the source of infection is a decayed tooth, either its removal or opening of the tooth cavity is indicated. Then a skin incision is made and, if necessary, adipose tissue is dissected. In most cases, incision of the skin followed by pushing apart the soft tissues with the jaws of a hemostatic clamp is sufficient. Usually, the pus comes out under pressure and in large quantities. There is no need to inspect the abscess cavity. This is the main difference between intervention for adenophlegmon and that for osteophlegmon. In the case of the latter, the tissue must be cut up to the periosteum inclusive, and through this wound, the bone should be inspected and drained, with one end of the drainage installed on the bone. A bandage is applied to the wound. Dressings are carried out daily. General treatment is mandatory. The patient receives a complex of anti-inflammatory, antibacterial and, if indicated, detoxification therapy in age-specific dosages. Treatment is inpatient.

How to determine adenophlegmon

Adenophlegmon is an abscessive inflammatory process that occurs in the subcutaneous fatty tissue (characterized by the absence of boundaries of the purulent focus) and is localized in the area of ​​the lymph nodes - most often the supramandibular, submandibular, chin and ear are affected.

Causes and pathogenesis

The formation of a purulent focus in the structure of the lymph node occurs due to the penetration of an infectious agent, a sharp weakening of immune defense and disruption of the barrier functions of the lymphatic system, caused by:

• previous infectious and inflammatory disease;
• severe vitamin deficiency;
• injury to soft tissues;
• neglect of the rules of asepsis when performing injections.

The development of an acute inflammatory process leads to the cessation of the outflow of lymphatic fluid; waste products of pathogenic microorganisms freely penetrate through the walls of the lymph node into nearby tissues and begin to form a purulent focus.

Symptoms and first signs

The early stage of adenophlegmon is characterized by :

• general malaise;
• rapid fatigue;
• decreased appetite;
• increased sweating;
• the appearance of a swelling in the area of ​​the lymph node that is painful on palpation.

The progression of the purulent-inflammatory process is accompanied by an increase in body temperature, hyperemia of the affected area, the appearance of signs of fluctuation, damage to adjacent areas of subcutaneous fat and damage to vital organs.

Diagnostics

If adenophlegmon is suspected, the following diagnostic measures are carried out:

"Phlegmon of the neck"

General information about phlegmon of the neck and its ultrasound diagnosis.

Description of the disease

Diffuse purulent inflammation develops in the subcutaneous fat and is not limited to one area. The inflammatory process can spread rapidly, threatening the patient's life. Severe pathology can ultimately lead to sepsis. Therefore, when you notice the first symptoms, it is important to seek medical help.

Cellulitis most often develops as a complication of another infectious disease. In this case, the pathological microflora enters the fatty tissue from other systems of the body through the blood and lymph flow. Secondary phlegmon often develops if the patient does not adequately treat purulent processes (furunculosis, carbuncles, abscesses). In most cases, the causative agent is Staphylococcus aureus. Less commonly, other pathogenic organisms - E. coli, streptococcus, Proteus - can be detected during the diagnostic process.

Primary phlegmon develops quite rarely due to the introduction of pathogenic microorganisms into the soft tissues through wounds or cuts on the neck.

Cellulitis is severe due to diabetes mellitus. Rotting processes occur at an accelerated pace. In 10% of cases the disease is fatal.

Classification

Inflammation can occur in acute and chronic forms. In the second case, the disease is characterized by a sluggish course and the absence of acute symptoms. There are periods of remission, when any complaints are completely absent, and exacerbations, when all the symptoms characteristic of the acute form of the disease appear.

Depending on the depth of the inflammatory process, the following forms of the disease are distinguished:

• deep phlegmon (inflammation is localized under the connective membrane of the muscles);
• superficial phlegmon (pathogenic microflora develops in the subcutaneous tissue).

Depending on the location of the infection, the following types of disease occur:

• mental phlegmon;
• submandibular phlegmon (often occurs as a complication of diseases of the molars);
• phlegmon of the posterior surface of the esophagus;
• phlegmon of the sternal fossa;
• phlegmon of the anterior surface of the trachea;

Also, all phlegmons are divided into unilateral and bilateral. If we are talking about a unilateral form of the disease, there are:

• phlegmon of the back of the neck;
• phlegmon of the anterior surface of the neck;
• lateral phlegmons.

Cellulitis of the neck is a dangerous pathology that threatens life

Depending on the factors contributing to the development of the disease, the following forms of secondary phlegmon are distinguished:

• tonsillogenic (inflammatory process provoked by throat diseases);
• odontogenic (infection enters the soft tissues of the neck from diseased teeth or gums).

Based on the morphological changes occurring in the infected area, the following types of phlegmon are distinguished:

1. Serous. This is the initial stage of the pathological process, which is characterized by the absence of a clear boundary between healthy and affected tissues and the formation of exudate.
2. Purulent. A purulent exudate forms, the tissues swell, and a fistula may appear.
3. Putrid. There is tissue destruction with the formation of gases and an unpleasant odor.
4. Necrotic. In the area of ​​inflammation, necrotic foci are formed, followed by tissue rejection. Ulcers may develop.
5. Anaerobic. A secondary anaerobic infection joins the inflammatory process.

Cellulitis of newborns is another form of the disease, which is quite rare and develops at 2-3 weeks of a baby’s life. The inflammatory process is preceded by a persistent decrease in immunity. The risk of developing the disease increases if the mother experiences a bacterial infection in the last months of pregnancy.

Reasons for the development of inflammation in the neck

The disease develops as a result of penetration into the fatty tissue through a wound on the neck or through the flow of blood and lymph from other foci of infection. However, the presence of pathogenic microflora in the body does not mean that you will have to deal with phlegmon. Immunity is of great importance. If the body's defenses are working at full strength, bacteria will not be able to fully reproduce.

The following factors can become a trigger for the development of neck phlegmon:

1. Diseases of the lower jaw. Foci of infection such as pulpitis, caries, periodontitis, and gingivitis can provoke infection of the soft tissues of the neck.
2. Throat infections. People with chronic tracheitis, tonsillitis, pharyngitis, and laryngitis are at risk.
3. Inflammation of the lymph nodes.
4. Neck injuries. Through scratches and abrasions, the infection can penetrate into the deep layers of the epidermis, provoking a purulent process.
5. Any infectious diseases. Pathogenic microflora enters soft tissues through the blood and lymph flow.

In some cases, phlegmon may develop not due to pathological microflora, but due to exposure to chemicals. Thus, purulent inflammation in the subcutaneous tissue of the neck will develop with the introduction of turpentine, gasoline, etc.

Symptoms

The disease in its acute form begins with a sharp increase in body temperature to 39–40 degrees. In this case, the patient has signs of general intoxication of the body:

• headache;
• reduced blood pressure;
• weakness;
• chills;
• thirst;
• sleep disturbance.

With superficial phlegmon, redness and swelling appear in the affected area. When palpating the inflamed area, the patient feels acute pain, and regional lymph nodes become enlarged. Cellulitis may be hard to the touch, and there is a local increase in body temperature (the inflamed area seems hot).

Pain at the gate of the head is one of the signs of the disease.

In deep forms of phlegmon, general symptoms are more pronounced (weakness, fever, headache, etc.). In the early stages, changes in the area of ​​inflammation may not be noticeable. Severe pain is caused by turning the neck. The patient tries to limit his movements. As deep inflammation develops, symptoms also begin to appear in the upper layers of the epidermis. Swelling develops, the skin begins to become shiny.

If purulent masses are present inside the phlegmon, the tumor becomes loose. Pressing on the inflamed area may leave a dent. The pus forms a fistula and begins to come out or spread to neighboring tissues, aggravating the inflammation. As the affected area grows, the patient develops breathing problems due to swelling of the larynx. Body temperature can rise to 42 degrees. There is a serious risk to the patient's life.

Diagnosis of the disease

A qualified surgeon can detect superficial cellulitis during the initial examination. Deep forms of the disease require more careful differential diagnosis . In addition, it is important to identify what pathogen provokes the inflammation in order to prescribe adequate therapy.

A specialist can use the following techniques:

1. Palpation of the inflamed area. Changes in the temperature of the affected area, sharp pain, absence of clear boundaries of the tumor - these symptoms indicate the development of phlegmon.
2. Patient interview. The doctor clarifies when the first symptoms appeared and what preceded them. It is possible that phlegmon is a complication of a disease of the throat or oral cavity.
3. General blood analysis. A change in blood composition may indicate the development of an inflammatory process.
4. General urine analysis.
5. Ultrasonography. The technique allows you to determine the localization of inflammation in deep forms of the disease.
6. MRI of the affected area. The study also helps determine the volume and nature of inflammation. The technique is not used in all clinics due to the high cost of the equipment.
7. Puncture of the inflamed area under ultrasound control. The specialist studies the obtained material and determines what pathogen provoked the inflammatory process. In accordance with the information received, medications are selected for antibacterial therapy.

Ultrasound examination of neck phlegmon.

Ultrasound examination has a number of advantages over other methods. In particular, there is the possibility of dynamic monitoring of the process, the possibility of contact between the specialist and the patient during the examination, allows for monitoring of treatment, and provides the possibility of timely controlled puncture of the object under study for the administration of medications or collection of material for research. Ultrasound does not require much time to perform and has no side effects, which emphasizes the promise of this method. Modern Doppler techniques provide the ability to assess the vascular response in the area of ​​detected changes, while the sensitivity of the method reaches 93%. Ultrasound makes it possible to detect infiltrates and fluid accumulations that do not appear clinically in the early stages before the development of a purulent process. Ultrasound criteria for purulent tissue damage are the presence of characteristic changes in the structure of soft tissues - a decrease in their echo density with disruption of the normal anatomical structure, as well as the presence in the soft tissues of a zone of increased echo density with heterogeneous hypoechoic inclusions, as well as gas inclusions. Ultrasound makes it possible to determine the exact localization of the inflammatory focus, its depth and determination of blood flow parameters.

Ultrasound, along with high accuracy in diagnosing inflammatory changes in soft tissues, has other advantages over alternative imaging methods: it does not expose the patient and the doctor to radiation, allows monitoring the object of interest and the process of needle insertion during puncture in real time, and maintains the doctor’s contact and the patient. Ultrasound examination is most comfortable for the patient. The mobility of ultrasound devices makes it possible to use them in an operating room or intensive care unit, when it is impossible to transport the patient, for example, when performing artificial ventilation.
