Acquired medial external auditory canal stenosis, anterior tympanomeatal angle blunting, and lateralized tympanic membrane: Nosology, diagnosis, and treatment.

Objectives: To analyze the etiologies, auditory consequences, diagnostic tools and therapeutic results of three often confused pathologies: acquired fibrous stenosis of the medial part of the external auditory canal (EAC), fibrous anterior tympanomeatal angle blunting, and lateralized tympanic membrane.

Material And Methods: Retrospective study of 18 cases operated on over a 16-year period (14 patients: 7 female, 7 male; aged 11-64 years): 8 cases of medial EAC stenosis, 3 of blunting, and 7 of tympanic membrane lateralization.

Results: In all 3 pathologies, otoscopic and radiologic diagnosis was easily established, so that they could not be confused.
