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 during otitis media is disrupted.

Two forms of exostoses are observed - on the peduncle and flat. Exostosis on the button comes from the outer ring of the bony part of the ear canal. They are diagnosed with otoscopy and radiography, often as an accidental find. Leg exostoses are easily knocked off with a flat chisel under local infiltration anesthesia endaurally.
Relapses are not noted.

Flat exostoses often occupy almost the entire length of one of the walls of the ear canal. Sometimes they form in the region of the tympanic ring, causing thickening of the walls of the tympanic cavity. Flat exostoses are multiple and make otoscopy difficult.

Indications for the removal of flat exostoses are made with caution, since surgical trauma often does not match the benefits received. The operation is partially performed behind the ear. The tissue of exostoses is dense and removing them with a chisel requires the application of force, which is associated with the possibility of damage to the structures of the middle ear and facial nerve.

External auditory canal exostoses

  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, 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. 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 the elderly and senile age, the walls of the ear canal collapse due to the loss of their elasticity, which leads to
  4. 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 washing, 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
  5. External auditory canal cleansing
    Purpose To clean the patient’s ears. 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 meatus. 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 secret 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 by
  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. 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
  12. Peripheral Hearing Analyzer
    The peripheral part of the auditory analyzer, or the ear itself, anatomically consists of three parts: the outer, middle and inner ear (Fig. 4). Fig. 4. The structure of the organ of hearing: 1 - cartilage of the auricle; 2 - external auditory meatus: 3 - eardrum; 4 - auditory tube; 5 - auditory ossicles; 6 - a labyrinth; 7 - the inner surface of the eardrum:
