메니에르병에서 내림프낭 수술과 전정신경절단술의 치험

Abstract

Meniere's disease is a disorder of the membranous labyrinth that is characterized by vertigo, gearing loss, tinnitus and ear fullness without the definitive causes. Surgical intervention of Meniere's disease is indicated when symptoms persist in spite of an adequate trial of medical therapy. This study reviewed eighteen cases of endolymphatic sac surgery and seven case of vestibular neurectomy which had been conducted from 1989 to 1992. Complete and substantial groups of vertigo grading were 61%(eleven cases) of decompression cases and 100%(seven cases) of neurectomy cases. Improved and unchanged groups of hearing change were 84% (fifteen cases) of decompression and in all of neurectomy cases. No disabillity was 63%(eleven cases) of decompression cases and 86%(six cases) of neurectomy cases. According to 1972, AAOO criteria, group A and B were 50%(nine case) of decompression group and 100%(six cases) of the neurectomy group. Five cases of sac surgery group required the second surgical trial due to recurrent vertigo.
