Abstract

Chinchillas were sensitized with human serum albumin (HSA). When circulating antibody-titers were sufficiently elevated as to induce local inflammation, 1 ml of HSA (50, 5, 0.5 mg/ ml) was instilled into the left middle ear cavity from the superior bulla. HSA containing a steroid agent was instilled into the right ear. Non-sensitized animals were used as control. In the sensitized animals, a significant hearing loss occurred at higher frequencies. The loss was dose-related. Less severe hearing loss was found following steroid treatment. We conclude that sensorineural hearing loss can occur in antigen-induced otitis media.
