ABSTRACT

Sudden sensorineural hearing loss (SNHL) develops usually in unilateral ear without known etiology. In contrast, bilateral sudden SNHL is mostly related to serious systemic diseases and have a severe hearing loss and poor prognosis compared than unilateral one. We describe here a 59-year-old man presented with a bilateral sudden SNHL and vertigo possibly attributed to dolichoectasia in vertebrobasilar artery, and discuss the possible mechanism.
