Exostoses of the external auditory canal

Exostoses are bone formations that are a consequence of osteodystrophic processes of the temporal bone. Some of them refer to benign neoplasms. Exostoses grow slowly, often asymptomatically in the form of exo- and hyperostoses. When obturation of the ear canal, ear noise appears, hearing loss, disruption of sulfur or pus in otitis media is disturbed.

Two forms of exostoses are observed - on the leg and flat. Exostoses on the bait come from the outer ring of the bony part of the ear canal. They are diagnosed with otoscopy and radiography, often as a random find. Exostoses on the pedicle are whipped easily with a flat chisel under local infiltration anesthesia and endaurally.
Recurrences are not observed.

Flat exostoses often occupy almost all over one of the walls of the auditory canal. Sometimes they are formed in the area of ​​the drum ring, causing thickening of the wall of the tympanic cavity. Flat exostoses are multiple and difficult to otoscopy.

The indications for removal of flat exostoses are placed with caution, since surgical trauma is often not consistent with the benefits obtained. The operation is partly produced by ear access. The fabric of exostoses is dense and their removal with a chisel requires the application of force, which is associated with the possibility of damage to the structures of the middle ear and the facial nerve.

Exostoses of the external auditory canal

  1. Boils of the ear canal
    Furuncle (otitis externa circumscripta) - acute purulent inflammation of the hair follicle, sebaceous gland with limited inflammation of the skin and subcutaneous tissue of the membranous-cartilaginous part of the external auditory canal. This and about l about g and I. The disease occurs as a result of the penetration of infection, often staphylococci, into the sebaceous and hair follicles during irritation of contaminated skin by manipulations in the ear
  2. Foreign body of the external auditory canal
    Foreign bodies in the external auditory canal are most often found in children when, during a 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 can be fragments of matches, pieces of cotton stuck in the ear canal at the time of cleaning the ear from
  3. Atresia and stricture of the external auditory canal
    Rubric atresia and strictures of the external auditory canal occur after injuries, burns, purulent otitis, complicated by external otitis, ulcerative processes in diphtheria, syphilis, lupus, etc. Narrowing of the external auditory canal is sometimes observed after a radical ear operation. In the elderly and senile age, there is a collapse of the walls of the ear canal due to the loss of their elasticity, which leads to
  4. Washing the external auditory canal
    Purpose: removal of the contents of the ear canal. Equipment: Janet's syringe, 2 kidney-shaped trays, towel, oilcloth apron, cotton balls, medicines. gloves. Algorithm of actions. Obtain the patient's consent for washing, explaining to him the purpose and course of the procedure. Plant patient side by side. Wear gloves. Put a towel on the shoulder of the patient, on top - oilcloth
  5. Purification of the external auditory canal
    Purpose To clean the ears of the patient. Indications The impossibility of self-service. Contra no. Possible complications When using hard objects damage the eardrum or external auditory canal. Equipment 1. Wadded turunda. 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 ear canal
    External diffuse omum (otitis exterra diffusa) is an acute or chronic infectious spilled inflammation of the skin of the external auditory canal. Occurs as a result of the penetration of infection through minor traumatic skin lesions, most often formed during manipulations in the ear. In addition, skin damage from chemical and thermal burns or injuries contributes to
  7. Sulfur cap of the external auditory canal
    The blockage of the external auditory canal with sulfur or with admixture of the epidermis is not uncommon. Under normal conditions, the secret of the sulfur glands, drying into lumps and crusts, falls out during chewing and talking as a result of movements of the mandibular joint and the anterior wall of the auditory canal. Excessive accumulation of sulfur may be due to the hyperfunction of sulfur glands under the influence of irritating
  8. Acquired stenosis of the ear canal. 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 canal furuncle
    The cause of microtrauma to the skin of the ear canal when picking in the ears, hypothermia, carbohydrate metabolism, hypovitaminosis. Symptoms Severe shooting pain in the ear, if you delay the earlobe or click on the trestle - the pain in the ear increases. Increased pain also occurs when chewing and yawning. The skin of the external auditory canal is reddened, swollen. The disease may be accompanied
  10. Acute duct eczema
    Cause Frequent local skin irritation of the ear canal with general eczema. Predisposing factor to the eczema of the ear canal is suppuration from the ear in chronic purulent otitis, as well as allergies, rickets, exudative diathesis, purulent inflammation of the middle ear, intestinal intoxication, sulfur plugs, frequent and improper use of ointments and lotions. Symptoms Itching. He may be so
  11. Diseases of the auditory nerve, pathways and auditory centers in the brain
    Lesions of the conductive part of the auditory analyzer can occur on any of its segments. The most frequent are the diseases of the first neuron, which are united in a group that received the name of the neuritis of the auditory nerve. This name is somewhat arbitrary, as this group includes not only diseases of the auditory nerve trunk, but also damage to the nerve cells that make up
  12. Peripheral Auditory Analyzer
    The periphery 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 - auricular cartilage; 2 - external auditory canal: 3 - eardrum; 4 - auditory tube; 5 - auditory ossicles; 6 - a labyrinth; 7 - the inner surface of the eardrum:
