Abstract

|
|
Cholesteatoma is a cystic mass that is formed by the keratinizing squamous epithelium in the tympanic cavity and/or mastoid and subepithelial connective tissue and by the progressive accumulation of keratin debris. It is one of the morbid diseases that could be missed by otologists. Cholesteatoma only in the mastoid and not in the middle ear has been reported only rarely in the literature. Mastoid cholesteatoma may be absolutely asymptomatic, and the diagnosis can occur after an incidental finding on imaging, hence the diagnosis is often delayed. In delayed diagnosis cases, the most common symptoms are otalgia, dizziness, or unexplained unilateral hearing impairment. We present a case of a huge, destructive mastoid cholesteatoma in a 43-year-old male who complained of intermittent otalgia and presented with attic retraction. Because the cholesteatoma in the mastoid was not connected with attic retraction, it was very difficult to definitively conclude whether the lesion was congenital or acquired. However, we suggest that it was a primary acquired type.
