전정파괴와 안면마비가 동반된 진주종성 중이염 1례

Aural cholesteatomas are epidermal inclusion cysts lined by a keratinizing squamous epithelium and have a tendency to destroy the surrounding bony structures. There are many theories of the pathogenesis of acquired cholesteatoma but up-to-date two of them are widely accepted, the invagination and invasion theory. Labyrinthine fistula is one of the most common complications of chronic otitis media(COM) with cholesteatoma and opening of the bony labyrinth often creates inner ear damage through the disturbance of the inner ear environment. Facial paralysis associated with COM may result from cholesteatomatous involvement of the fallopian canal. Cholesteatoma most commonly affects either the tympanic or second genu segments of the facial nerve. But extensive vestibular destruction and facial paralysis associated with COM with cholesteatoma are rare.

We have experienced a case of invasive cholesteatoma which causes vestibular destruction and facial paralysis. So, we report with review of literatures.
