At the spring meeting of the American Neurotology Society, Palm Beach, Fla, John F. Kveton, MD, Lahey Clinic, Burlington, Mass, reviewed two cases of delayed spontaneous recovery of hearing to preoperative levels several months after acoustic tumor resection. He theorized the possibility of a reversible conduction block of the cochlear nerve. While previous theories of transient hearing loss after surgery were attributed to spasm of the internal auditory artery or to direct mechanical trauma of the cochlear nerve during tumor manipulation, Kveton speculated that a conduction block phenomenon might exist. He went on to compare animal data with clinical intraoperative electrophysiologic data to further elucidate this pathophysiology.
