Abstract:
The authors have studied the induced acoustic otoemissions in 53 children with tubal malfunction. Otoemissions were present in 29% of all ears. In cases of retraction of the eardrum, the otoemissions were present in 2 of 23 ears. Some ears had no induced oteomission, with hypoacousia ranging from 10 to 15 dB only. Conversely, there were induced otoemissions in some ears while hypoacousia was as high as 25 dB.
