ABSTRACT

Intralabyrinthine schwannoma is a rare tumor arising from perineural Schwan cells of 8th cranial nerve. Intracochlear schwannoma(ICS) arising from cochlear nerve can have various type of sensoryneural hearing loss(SNHL) without vestibular symptoms. Hearing loss type of ICS was mostly progressive(48%), but sudden hearing loss was described in 15%.1) The authors experienced a case of ICS expressed by severe sudden SNHL after head trauma. We report this case with a review of the literature. (J Clinical Otolaryngol 2011;22:90–93)
