Atresia and strictures of the external auditory meatus

Ruby atresia and strictures of the external auditory canal occur after injuries, burns, purulent otitis media complicated by external otitis media, ulcerative processes in diphtheria, syphilis, lupus, etc. Narrowing of the external auditory canal is sometimes observed after radical ear surgery. In old and senile age, the walls of the ear canal collapse due to the loss of their elasticity, which leads to impaired patency of the ear canal.

Strictures and fouling can be in the membrano-cartilaginous or bone parts, from the thin membrane to the focal of the auditory meatus throughout, partial and complete. Partial strictures and atresia often do not cause complaints in the absence of discharge from the ear and hearing loss. Painful disorders appear mainly in connection with otitis media with difficulty in the outflow of discharge from the ear. In the presence of cholesteatoma, severe pain, swelling around the auricle, fever, and sometimes symptoms of septic or intracranial complications are noted in the middle ear. With the accumulation of earwax and desquamated epidermis, the inside of the narrowing can be a nuisance, because ear washing is contraindicated, and instrumental removal is limited by the size of the hole in the atresia.

The diagnosis of stricture of the external auditory meatus is made on the basis of otoscopy and sounding. It is more difficult to determine the depth of the stricture. A thin connective tissue diaphragm is recognized due to its flexibility when probing.
Bone deformities of the external auditory meatus or its overgrowing with bone tissue are detected by radiography and tomography.

The treatment of strictures and atresias is carried out surgically. Favorable outcomes of operations cannot always be guaranteed with deep overgrowths and strictures over a long stretch. Often, growths in the area of ​​the bony part of the ear canal during surgery are accompanied by a violation of the integrity of the eardrum and complication of otitis media. If the disorders of auditory and drainage functions are small, then it should be limited to observing the patient. A thin membrane is excised, then a drainage tube covered with a Tirshev flap in the area of ​​atresia is inserted into the ear canal. By the tenth day, the plastic flap grows to the wound surface. Then, a widening of the ear canal is carried out using plastic tubes. With overgrowths and strictures, they approach narrowing with the help of the behind-the-ear incision and excise scars. Then the bone canal is enlarged as in radical ear surgery. With purulent otitis media, an intervention is also performed on the middle ear. The remains of the skin of the auditory meatus are used in the plastic surgery of the new meatus. The entire bone wound is lined with a free skin graft. Sometimes they use non-free skin flaps on a leg from surrounding tissues. Military personnel are operated at district hospitals or the otolaryngology clinic of the Military Medical Academy.

Atresia and strictures of the external auditory meatus

  1. Boil of the external auditory meatus
    Furuncle (otitis externa circumscripta) - acute purulent inflammation of the hair sac, sebaceous gland with limited inflammation of the skin and subcutaneous tissue of the membrano-cartilaginous part of the external auditory canal. Et and about l about d and I. The disease occurs as a result of infection, more often staphylococci, entering the sebaceous and hair sacs when irritated skin is irritated by manipulations in the ear.
  2. Foreign bodies of the external auditory meatus
    Foreign bodies in the external auditory canal are most often found in children when during the game they push various small objects (buttons, balls, pebbles, peas, beans, paper, etc.) into their ears. However, in adults, foreign bodies are often found in the external auditory canal. They may be fragments of matches, pieces of cotton, stuck in the ear canal at the time of clearing the ear from
  3. External auditory canal flushing
    Purpose: removal of the contents of the external auditory meatus. Equipment: Janet syringe, 2 kidney-shaped trays, towel, oilcloth apron, cotton balls, medicines. gloves. Algorithm of actions Obtain patient consent for rinsing, explaining to him the purpose and course of the procedure. Set the patient sideways to himself. Wear gloves. Put a towel on the patient’s shoulder, oilcloth on top
  4. External auditory canal exostoses
    Exostoses are bone formations resulting from osteodystrophic processes of the temporal bone. Some attribute them to benign neoplasms. Exostoses grow slowly, often asymptomatically in the form of exo- and hyperostoses. When obstruction of the ear canal appears ear noise, hearing loss, the process of excretion of sulfur or pus with otitis media is disrupted. Observed two
  5. External auditory canal cleansing
    Purpose To clean the ears of the patient. Indications Inability to self-service. Contraindications None. Possible complications When using hard objects, damage to the eardrum or external auditory canal. Equipment 1. Wadded turunds. 2. Pipette. 3. Beaker. 4. Boiled water. 5. 3% hydrogen peroxide solution. 6. Disinfectant solutions. 7. Tanks for disinfection. 8. Towel.
  6. Spilled inflammation of the external auditory meatus
    External diffuse omum (otitis exterra diffusa) is an acute or chronic infectious diffuse inflammation of the skin of the external auditory canal. It occurs as a result of the penetration of infection through minor traumatic skin lesions that occur most often during manipulations in the ear. In addition, skin injuries due to chemical and thermal burns or injuries contribute to
  7. Sulfur cork of the external auditory meatus
    Blockage of the external auditory canal with sulfur or with an admixture of the epidermis is a common occurrence. Under normal conditions, the secretion of the sulfur glands, drying up into lumps and crusts, falls out when chewing and talking due to movements of the mandibular joint and the anterior wall of the ear canal. Excessive sulfur accumulation may be associated with hyperfunction of the sulfur glands under the influence of irritating
  8. Acquired stenosis of the external auditory meatus. H-61.3
    {foto46} Treatment outcome: Clinical criteria for improving the patient's condition: 1. Normalization of laboratory parameters. 2. Improving the clinical symptoms of the disease (lowering
  9. Auditory meatus furuncle
    Cause Microtrauma of the skin of the external auditory canal when picking in the ears, hypothermia, impaired carbohydrate metabolism, hypovitaminosis. Symptoms Strong shooting pain in the ear, if you pull off the earlobe or press on the tragus - the pain in the ear increases. Increased pain also occurs with chewing and yawning. The skin of the external auditory meatus is reddened, swollen. The disease may be accompanied.
  10. Auditory canal eczema
    Cause Frequent local irritation of the skin of the ear canal with general eczema. Predisposing factor for eczema of the auditory canal is suppuration from the ear in chronic suppurative otitis media, as well as allergies, rickets, exudative diathesis, purulent inflammation of the middle ear, intestinal intoxication, sulfur plugs, frequent and incorrect use of ointments and lotions. Symptoms of Itching. He can be so
  11. Esophageal stricture
    - narrowing of the esophagus associated with congenital or acquired factors Classification of cicatricial narrowing of the esophagus (G. L. Ratner, VI Belokonev, 1982) By etiology: burns with acids, alkalis, other burns By the time of obstruction: early (3-4 weeks), late (later than 1 month) According to the mechanism of development and clinical manifestations: A. Functional obstruction of the esophagus 1.
  12. Diseases of the auditory nerve, pathways and auditory centers in the brain
    Lesions of the conduction department of the auditory analyzer can occur on any part of it. The most common are diseases of the first neuron, united in a group called the auditory nerve neuritis. This name is somewhat arbitrary, since this group includes not only diseases of the auditory nerve trunk, but also lesions of nerve cells that make up
  13. Esophageal atresia
    DEFINITION Atresia of the esophagus is a malformation in which the proximal and distal ends of the esophagus do not communicate with each other. CODE ICD-Q39.0 Atresia of the esophagus without fistula. Q39.1 Atresia of esophagus with tracheoesophageal fistula. Q39.2 Congenital tracheoesophageal fistula without atresia EPIDEMIOLOGY Among newborns with esophageal atresia, about 30% are premature. CLASSIFICATION Accepted
  14. Pulmonary Atresia
    Typically, there is a lack of normal communication between the ventricles of the heart and the pulmonary artery. The literature data indicate significant variability of the defect among newborns - from 0.0065 to 0.02%. Among all CHD, the proportion of ALA ranges from 1.1 to 3.3%, increasing among critical CHD to 6.3%. This pathology is determined in two main versions: • atresia of the pulmonary artery with DMS; • atresia
  15. Extrahepatic bile duct atresia
    synonyms Biliary atresia, obstruction of extrahepatic bile ducts. DEFINITION OF AVS is a progressive obliteration of the extrahepatic bile ducts, which begins during the period of intrauterine development, with the gradual involvement of the intrahepatic bile system and the formation of biliary cirrhosis. CODE ICD-Q44.2 Atresia of the bile ducts. EPIDEMIOLOGY AID - the most common cause
  16. Single ventricle and tricuspid atresia
    There is a wide range of CHD in which there are no two normally developed ventricles. In these cases, various terms are used, but the most successful and widespread is the term “single ventricle”. A characteristic feature of pathology is the connection of the atrial cavities with only one, well-developed and dominant ventricle, in contrast to a normal heart, when the cavity of each
  17. Atresia of the pulmonary artery with intact ventricular septum
    The pathology frequency is about 0.06-0.07 per 1000 newborns, 1-3% among all CHD, 3-5% among critical CHD. For this variant of the defect, normally formed atria and concordant atrioventricular connections are characteristic; interventricular septum intact. There is no exit from the right ventricle: approximately 75% of cases are due to the complete fusion of the valves
