Round window membrane rupture [PDF]

The Laryngoscope, 1978
AbstractRound Window Membrane Rupture is a surgically correctable cause of sudden hearing loss and vertigo. Reported is a 19‐year‐old male who had proven round window membrane rupture secondary to barotrauma. Surgical exploration revealed an abnormally large round window niche and membrane, possibly predisposing him to this injury.
