Inner ear barotrauma from scuba diving

Abstract

Inner ear barotrauma among scuba divers is believed to be caused by any of three conditions: a hemorrhage in the inner ear, a tear of the labyrinthine membrane, or a perilymphatic fistula. These injuries may occur concurrently or separately. Hemorrhage and membrane rupture are managed conservatively, while fistula requires surgical repair. In this report, we describe three cases of inner ear barotrauma in scuba divers. We also discuss the proposed etiologies of this injury and the controversy over whether or not divers who have suffered an inner ear trauma can safely resume scuba diving. Although the older literature clearly suggests otherwise, we believe that scuba divers who completely recover from inner (or middle) ear barotrauma may return to diving as long as they exercise caution and care.
