An Osteoma of the Middle Ear Presenting with the Tullio Phenomenon.

Abstract

The Tullio phenomenon is an extremely rare condition in which loud noise induces a brisk vestibular response. Osteomas of the middle ear cleft are also uncommon. We report a patient with an osteoma of the middle ear cleft that became symptomatic with progressive facial palsy and mixed hearing loss. The onset was heralded by the Tullio phenomenon, which she had experienced for 10 years. The differential diagnosis of the Tullio phenomenon and the management of middle ear osteomas are discussed.
