Abstract: Cholesteatoma is inflammatory granulation tissue that trigger chronic otitis media with deteriorating adjacent structure and induce several complications such as facial nerve palsy, perilymph fistula and rarely, intracranial problem. About 8% of cholesteatoma, perilymphatic fistula is detected at the time of diagnosis. In case of otorrhea with destructed external auditory canal, cholesteatoma should be considered and also other malignancy couldn’t be excluded. Additional imaging modality such as computed tomography and magnetic resonance imaging with diffusion weighted image are recommended for evaluation of whole structure of temporal bone. We report a case of a giant cholesteatoma who visit with otorrhea and stenosis of external auditory canal which complicated with eroded semicircular canal, facial canal, posterior fossa plate, and removed completely without hearing loss or facial palsy.; Keywords : Cholesteatoma, Facial paralysis, Perilymph, Fistula
