A 45-year-old female complained of right hearing loss with fullness in recent months. She underwent right tympanoplasty type I about 4 years ago. On physical and otoscopic examination, a pearl-like mass about 3 x 4 mm in size over central part of right ear drum was noted. Pure tone audiometry test showed 35 decibel (dB) average hearing loss of right ear, and 20 dB of left ear. Tympanogram test showed bilateral type A. Computed tomography with thin cuts of the temporal bone revealed a 3 x 4 mm soft tissue mass over central part of right ear drum. Excision of the mass under microscope was smoothly done. A cholesteatoma was confirmed by pathology. She was uneventful during a regular follow-up. Cholesteatomas are benign collections of keratinized squamous epithelium within the middle ear. A cholesteatoma usually occurred in middle ear cavity or mastoid region, sometimes in external auditory canal. Tympanic membrane cholesteatomas were seldom reported.
