Abstract

The macula utriculi was irradiated with argon laser through the stapedectomized oval window. Singular neurectomy was also done.
After surgery, the patien's symptom disappeared or impproved.
Hearing was preserved in one patient. Unfortunately another patient lost hearing in 3 month. The other patient was already deaf before the operation.
Balance was improved within one week postoperatively. Caloric responce was observed in two patients.
