Effect on Hearing Thresholds of Surgical Modification of the External Ear

Abstract
Modifications of external ear anatomy following tympanomastoid surgery can have significant effects on the hearing threshold. Experiments are described that demonstrate the acoustical effect of changes in the dimensions of the concha and ear canal on external ear sound pressure gain. An attempt is made to correlate these findings with results in 30 post-tympanomastoidectomy ears and develop some basic principles of external ear surgery that might be clinically useful.
