[Variation of the tinnitus on moist tubotympanical catarrh and otosclerosis before and after operation (author's transl)].

The tinnitus on moist tubotympanical catarrh and otosclerosis had been registered before and after the operation in relation to the frequence and the audibility. 222 children ears and 55 adult with a moist tubotympanical catarrh had been studied. Of these 28 children 26 adult ears had a tinnitus. After the operation and after using a "Donaldson silicone Drain Tube" without relation of the tinnitus there had been reached a very good win of hearing and excepted for 6 adults, whose tinnitus only had been lower, and elimination of the tinnitus. In 65 patients from 71 patients with stapedectomy it was able to look out for the tinnitus before and after the operation. Before the operation 44 patients had no tinnitus and 21 patients had a very disagreeable tinnitus; 17 patients from these had after the stapedectomy no longer a tinnitus. The audibility of the tinnitus from 4 patients had been reduced very much. The result of hearing the management of the inner ear after the operation haven't had any relation to the tinnitus before the operation.
