Simultaneous and Sequential Bilateral Sudden Sensorineural Hearing Loss: Are They Different from Unilateral Sudden Sensorineural Hearing Loss?

Abstract

Simultaneous BSSHL, sequential BSSHL and USSHL may have a completely different profile and should not be managed as one disease. Hearing loss, underlying autoimmune diseases, antinuclear antibodies, and improvement/recovery of hearing loss vary in a degree that implies different pathophysiology and prognosis.
