Case Discussion

Large vestibular aqueduct syndrome (LVAS) is thought to be one of the most common congenital causes of sensorineural hearing loss (SNHL) and disequilibrium. It is usually sudden after head trauma or progressive during childhood. Cochlear implantation is the surgical effective choice of LVAS if marked hearing loss occured.
