Autoincudotomy as an uncommon etiology of conductive hearing loss: Case report and review of literature
Abstract
Ossicular pathology is a recognized etiology of conductive hearing loss. Ossicular pathology includes 2 main categories, that is, ossicular chain fixation and ossicular discontinuity. Ossicular discontinuity can be congenital or acquired. Auto-incudotomy is an uncommon form of acquired ossicular discontinuity that usually occurs as a sequel of spontaneous expulsion of cholesteatoma. Typically, it manifests with conductive hearing loss without evidence of cholesteatoma. In this report, we presented CT imaging finding of a 34-year-old male with tympanic membrane perforation and defective long process of the incus (auto-incudotomy) with minimal middle ear granulation tissue and adhesions, sequela of cholesteatoma. Radiologists should pay attention for evaluation of ossicles especially in patients presented with conductive hearing loss.
