We present a 43-year-old male patient who developed a giant cholesteatoma with lateral sinus obliteration and involvement of the posterior cranial fossa. The only complaints were left-sided aural discharges and total sensorineural hearing loss. Examination revealed a mass lesion consistent with cholesteatoma within the left middle ear. Computed tomography and magnetic resonance imaging showed a...

BACKGROUND Patients who undergo radiotherapy (RT) for nasopharyngeal carcinoma (NPC) may develop external auditory canal cholesteatoma (EACC). METHODS The records of patients with newly diagnosed NPC who had received concomitant chemotherapy and RT in a tertiary referral center from 1997 January to 2012 July were retrospectively reviewed. RESULTS RT-related external auditory canal cholestea...

Fibrous dysplasia is a slowly progressive benign fibro-osseous disease, rarely occurring in temporal bones. In these cases, most bony lesions developed from the bony part of the external auditory canals, causing otalgia, hearing impairment, otorrhea, and ear hygiene blockade and probably leading to secondary cholesteatoma. We presented the medical history of a 24-year-old woman with temporal mo...

Labyrinthine fistula, defined by a destruction of the bony labyrinth is one of the most feared complications during the evolution of a chronic otitis media with cholesteatoma. Relatively common, it represents 4-12% cases of chronic otitis media with cholesteatoma and essentially occurs in the lateral semi-circular canal (70-80% of cases). The abnormal opening of the bony labyrinth in the middle...

INTRODUCTION Congenital cholesteatoma is thought to be caused by inadequate folding of the epidermoid formation inside the middle ear cleft. During development of the middle ear mucosa, stratified squamous epithelium accumulates in the embryonic life. Its typical appearance is a "pearl" beneath the anterosuperior quadrant of the tympanic membrane. PRESENTATION OF CASE We report 28 years-old c...
