Menière's disease: results of treatment with the endolymphatic subarachnoid shunt compared with the endolymphatic mastoid shunt.

The senior author has performed 346 endolymphatic sac operations since 1971. Questionnaires were sent to these patients to evaluate the results of this surgery. One hundred ninety-six questionnaires were returned and formed the basis for this report. The results of surgery are reported by the new American Academy of Otolaryngology--Head and Neck Surgery criteria as well as by the older method of reporting. There is no significant difference in results between the endolymphatic subarachnoid shunt and the endolymphatic mastoid shunt. Because of the lower morbidity of the latter procedure the authors prefer the endolymphatic mastoid shunt. The new method of reporting is superior to the older method.
