In keratosis obturans found clumps of the epidermis in the ear canal caused by excessive formation of epithelial cells that do not migrate toward the outer ear.
Althoughit can be caused by obliterabs hyperemia increase desquamasi and formation of epidermal keratin debris. Abnormal migration is probably due to an inflammation that is triggered because of a virus.

Viral infections commonly cause this problem. Is also caused by abnormal migration of squamous epithelium lining the deep portion of the external auditory canal. Cutaneous keratosis, ulcer, atrophy, and necrobiosis L82—L94— Treatment is done with regular mikrosuctin until the buildup of debris in meratosis outside telingta reduced.
Canal plasty is helpful in recurrent cases 3. Views Read Edit View history. This led to the widening of the bones in the MAE is accompanied by inflammation of the epithelium.
External auditory canal cholesteatoma: This is caused due to acute inflammation involving the external ear canal. Support Radiopaedia and see fewer ads.

This pathology associated denagan existence under the epithelium hyperplasia and chronic inflammation in tissues subepitelium. Piepergerdes and colleagues in stated that keratosis obturans produced by disease in the external kdratosis meatus skin whereas bone disease in external auditory meatus is the basis for cholesteatoma in external auditory meatus.

Primary auditory canal cholesteatoma: It can be confused for EAC cholesteatoma but they are completely different entities requiring different treatment. Clin Otolaryngol Allied Sci. As this blend ages, it de-hyrdates and oxidizes, thereby taking on a darkened appearance. Some speculate that oblitsrans obturans may be a symptom of a systemic condition, involving chronic sinusitis and bronchiectasis.
Usually treated by EAC toilet; due to a high incidence of recurrence, it may require several excisions of keratin plugs.
This condition can only be cured by removal. Pathogenesis Keratosis obturans occur because of abnormal migration of epithelial lining the ear canal skin.

Keratosis obturans is postulated to occur due to abnormal epithelial migration of ear canal skin. Once the ear canal is cleared, regular removal of accumulating skin cells is usually required to limit recurrence.
Keratosis obturans and external auditory canal cholesteatoma.
Care must be taken when removing a keratinized plug, as there may be bony destruction underlying the compacted skin, with possible exposure of the facial nerve. Obstruction of keratin on obturans keratosis looks like the geometric lines the external auditory meatus in that looks like a picture of onion skin. This should be differentiated from primary auditory canal cholesteatoma which is characterized by invasion of squamous tissue from the external ear canal into a localized area of bone erosion.
Ongoing mechanical clearing of the ear often leads to an eventual resolution of the condition. The first form there is a chronic inflammation in the subepithelial tissueand this is responsible for epithelial hyperplasia and accumulation of keratin in the external canal ear canal. Consequently a keratinized plug is generally harder in texture and lighter in colour than typical ear wax. The obstruction from keratosis obturans is different from ear wax, in that it forms in the inner half of the ear canal, as opposed to the outer half and does not contain the perspiration and oils that wax does.
