[Protects stapedectomy from increasing otosclerotic inner ear deafness? (author's transl)].

The favourable influence--first shown by Shambaugh--of fenestration operation used in cases of the otosclerosis which cause a rapid sensorineural hearing loss can also be stated for stapedectomy. A negative influence of stapedectomy on inner ear stability was not determined. Especially the ears whose inner ear function is very bad were favoured by this operation.
