In order to evaluate the influence of tympanoplasty upon tinnitus, the pre-and postoperative incidence of tinnitus who underwent tympanoplasty in our clinic was investigated.
Before the operation. 30% of all the patients had clinical symptom of tinnitus, and among those patients the ones with chronic otitis media had the highest incidence (35%). The preoperative tinnitus disappeared after tympanoplasty in 45% of the patients.
On the other hand, there was another type of tinnitus that appeared after tympanoplasty at an incidence of 12% and the frequency was highest (19%) in patients with cholesteatoma. Most of that type of tinnitus disappeared spontaneously a few days after the operation. Patients with tympanoplasty type III and IV had a higher frequency of tinnitus than those with tympanoplasty type I and myringoplasty.
Manipulation of the stapes and its surroundings seemed to cause the tinnitus relatively often.
