Trismus and TMJ disorders as first clinical manifestations in an intracranial acquired cholesteatoma

Chiara Copelli et al. BMJ Case Rep. .

Abstract

Intracranial extension of acquired cholesteatoma is a rare occurrence that can develop secondary to trauma, chronic otitis media or acquired aural cholesteatoma. The most commonly observed symptoms are headache and hearing loss. The authors report on a rare case of intracranial cholesteatoma presenting with atypic symptoms: swelling and temporomandibular joint disorders.

Keywords: head and neck surgery; neurosurgery; otolaryngology / ENT.
