Case 2. 7 years old girl. Patients right ear was totally deaf and the left ear showed percepti- ve deafness with 35db. hearing loss. X ray irradiation of Eustachian tube was done on the left side. After the treatment her hearing improved, and audiometrical test proved her left ear had the normal hearing. Reviewing the literature, there are some reports that after tonsillectomy or sinus operation for the patients with the innerear deafness, their hearing remarkably improved.
