Cholesteatoma of external auditory canal: a case report

Abstract

Cholesteatoma is a common occurrence in the middle ear. Cholesteatoma of the external auditory canal (EAC) is a rare entity. We report the first case of our department of cholesteatoma of the EAC limited to the posterior wall, in a 14-year-old patient presented with chronic left purulent otorrhea. We performed a canalplasty under general anesthesia. Debris of keratin were removed and the eroded bone was curetted. We repaired the bony erosion with the tragal cartilage. Two years after the surgical procedure, there was no evidence of recurrence. Clinical symptoms of EAC cholesteatoma are not specific. It is therefore important to think about cholesteatoma when a patient presents with chronic otorrhea with intact tympanic membrane.
