Abstract : A hearing loss brought about by infection after middle ear surgery in a Cebus capucinus monkey was detected on an audiogram elicited by a shock-avoidance technic. Stable prepathology thresholds to five pure-tone frequencies had been established previously, and the course of infection and recovery after treatment was clearly demonstrated. This threshold measurement technic proved valuable in detecting the results of middle ear surgery and in describing changes in hearing during ear pathology. (Author)
