Shunt surgery in Meniere's disease: a follow-up report.

Between December 1969 and May 1986, 140 patients were treated for Menière's disease using the endolymphatic sac subarachnoid shunt. The technique and results are contrasted with an earlier report. The surgical technique described includes modifications of the originally described procedure. A microcomputer was used for the storage and manipulation of data based upon 1972 Academy criteria. Control of vertigo was accomplished in 83% of patients; 51% of patients were graded class A or B, according to the 1972 Academy criteria. No serious complications occurred. Problems included the potential for serious complications, the lack of specific criteria for patient selection, and the continued deterioration of hearing with the passage of time. Comparison of data with those presented in 1973 indicates a lower overall success rate, but continued success in the management of vertigo and imbalance. The endolymphatic sac subarachnoid shunt is worthy of consideration in the management of Menière's disease when surgery is indicated and retention of hearing is desirable.
