• Change of Auditory Function before and after Vestibular Neuretomy

抄録

Retrosigmoid vestibular neurectomy was performed on 12 patients being suffered form intractable vertigo during past 4 years. These included 11 Meniere and 1 delayed endolympahtic hydrops patients. Control for vertigo was satisfactory in all subjects. Long term follow up of their hearing revealed that it was preserved in 90.9% of patients. Their auditory function was also examined by the electro-cochleo graphy (ECoG). There was no change in -SP/AP ratio before and after the surgery. -SP/AP ratio measure on the affected side decreased when white noise was applied on the contralateral intact ear before RSVN. However, the reduction was no more found after the surgery. It was concluded that the crossed olivo cochlear bundle was also severed by RSVN.
