Abstract:
Complications of cholesteatoma result from characteristic inflammatory and resorptive processes that erode the structures of the middle and inner ear with potential to spread locally. Common intratemporal complications include hearing loss, facial nerve palsy, labyrinthine fistula, and dysgeusia. Extratemporal complications, though less common, may be life-threatening, and include cerebrospinal fluid leak and encephalocele, meningitis, epidural and intraparenchymal abscesses, subdural empyema, and otic hydrocephalus.
