Sudden Sensorineural Hearing Loss

Sudden sensorineural hearing loss is hearing loss that results from damage to either the cochlea or the cochlear nerve.

Overview of Sudden Sensorineural Hearing Loss

Typically, patients with atraumatic sudden hearing loss experience a sudden loss of hearing in one ear. It may be related to a viral infection just prior to the event or completely without any provoking event (idiopathic). Associated symptoms can include tinnitus, disequilibrium, and/or vertigo. The disequilibrium/vertigo almost always resolves as the vestibular system in the brain compensates and adapts. This condition resolves more rapidly in patients who take less "anti-dizzy" medications such as Valium or meclizine.
