Cochleosacculotomy.

In 1982 and 83, we performed cochleosacculotomies on 12 patients, of which nine have been retained for the present study. The operation was carried out on patients affected by unilateral Ménière's disease with a hearing loss stabilized at 50 dB or more at speech frequencies. All patients were suffering incapacitating vertigo which was perfectly controlled in all the cases operated so far. On the other hand, the hearing results were much les satisfactory in that eight of the nine cases had no serviceable hearing after the operation. It is concluded that, in our hands so far, this cannot be considered as a conservative surgical procedure, but it is an alternative for the control of vertigo in Ménière's disease.
