Bilateral sudden sensorineural hearing loss (SNHL) represents a rare disease entity, constituting less than 5 % of all sudden SNHL cases. Unlike unilateral disease, bilateral sudden SNHL appears to be mostly related to serious systemic pathology, and is associated with a more severe degree of hearing loss, poorer prognosis following treatment, and more significant impairment in morbidity and overall quality of life.
