Labyrinthitis ossificans is fibrosis or ossification of the membranous labyrinth. Tympanogenic, meningogenic, and hematogenous etiologies are more common than trauma in the development of labyrinthitis ossificans. We present a case complaining of right-sided hearing loss and symptoms of otitis media and positional vertigo resulting from perilymphatic fistulization. Imaging revealed labyrinthitis ossificans secondary to temporal bone fracture crossing through the otic capsule.
