Advancing Cholesteatoma Secondary to Acquired Atresia of the External Auditory Canal: Clinical Perspectives
Acquired atresia of External Auditory Canal (EAC) is seldom encountered in routine otolaryngology practice. Apart from resulting in moderate-to-severe conductive hearing impairment, it is a potentially dreaded condition which might lead to canal cholesteatoma. Suspected to develop as a consequence...

Acquired atresia of External Auditory Canal (EAC) is seldom encountered in routine otolaryngology practice. Apart from resulting in
moderate-to-severe conductive hearing impairment, it is a potentially dreaded condition which might lead to canal cholesteatoma.
Suspected to develop as a consequence of a pre-existing chronic otitis externa/media, the EAC atresia leads to proximal (medial)
accumulation of desquamated epithelium and denatured keratin (the canal cholesteatoma) that further leads to aggravation of
the chronic otitis, thereby initiating a vicious cycle. The canal cholesteatoma might progress unhindered into the middle ear and
mastoid cavity, with its characteristic bone-eroding property, producing complications. A high index of clinical suspicion along with
proper imaging are therefore essential to apprehend the disease progression in a patient presenting with an apparently innocuous
EAC stenosis/atresia. In this report, we illustrate the clinical details of a young girl with unilateral acquired EAC atresia where canal
cholesteatoma had turned extensive, invaded the middle ear cleft, and produced a post-aural fistula, thereby establishing one of
the extreme outcomes of chronic otitis. |
