Ear canal exostoses are bony growths in the ear canal. Swimming in cold water often causes them. Ear canal stenosis can be caused by repeated ear canal infections that cause scarring. Some children are born with stenosis. Children with exostoses or stenosis often have many ear canal infections.
6 sie 2023 · Acquired stenosis of the external ear canal (ASEEC) is a relatively uncommon condition. Stenosis or narrowing of the external ear canal (EEC) occurs lateral to the tympanic membrane resulting in a skin lined blind canal. Recurrent otorrhea, and conductive hearing loss are typical clinical features.
What Is Ear Canal Stenosis? Ear canal stenosis is a narrow ear canal. Most kids with the condition were born with it. In some kids, the outer ear and eardrum don’t form normally. The parts of the inner ear, including the auditory (hearing) nerve, are usually normal.
In the setting of a congenitally narrow (≤3 mm) ear canal, two important issues must be addressed: hearing status and the ear canal’s ability to self-clean. Aural stenosis is usually seen with a normally developed auricle, so otomicroscopic examination is not only possible but essential.

This paper reviews the causes, pathogenesis, assessment, and management options for external auditory canal stenosis. Recent findings: Initially, acquired external auditory canal stenosis was described as resulting from a number of different causes.
Ear canal stenosis can happen in one or both ears. If the stenosis is mild, that may be the only sign. In more severe stenosis, kids may have hearing loss (because the sound can’t get through the narrow ear canal) and frequent infections of the ear canal (otitis externa).
