Acquired External Ear Canal Stenosis

Acquired External Ear Canal Stenosis

Description : In some cases, the lumen may be reduced to a tiny pinhole behind which desquamated keratin may be trapped.

Treatment guidelines
When the stenosis is responsible for the accumulation of wax or keratin debris in the medial portion of the canal, surgical excision may be indicated.

This condition, at its most extreme, may cause a total occlusion of the external canal (a false fundus).

The lumen of the deep canal in this patient has been narrowed to a pinpoint as the result of recurring episodes of otitis externa.
