Bilateral sudden sensorineural hearing loss following unilateral temporal bone fracture.

Temporal bone fractures usually cause unilateral sensorineural hearing loss (SNHL) by fracture that violated otic capsule of that side. Bilateral SNHL from unilateral temporal bone fracture were rarely seen. Labyrinthine concussion was considered to be the pathogenesis in these cases. This article reports an additional case of bilateral SNHL from unilateral temporal bone fracture but in a different pattern of SNHL which may result from an occlusion of the internal auditory artery.
