Arch Otolaryngol. 1962;75(5):422-423. doi:10.1001/archotol.1962.00740040433008
Abstract

The report by Ventry, Chaiklin, and Boyle of 2 cases of collapse of the external auditory canal during audiometry1 serves to emphasize a previously more or less neglected phenomenon and also to underline the importance of close professional interaction between otologist and audiologist. We began an investigation of the phenomenon of ear canal collapse during August, 1960. We were prompted to an investigation of this phenomenon more by observed and unexplained discrepancies between tuning fork observations and audiometric test results than by the inconsistencies in test results referred to by the previous writers.

The possibility of ear canal collapse during audiometry was first suggested to us by a number of cases in which air-conduction bone-conduction gaps indicated by routine audiometry exceeded 20 db. but were not accompanied by negative Rinne responses when tuning forks were used. When a plastic stopple of the type used in preliminary hearing-aid evaluations was
