经后颅窝行前庭神经切除术是治疗梅尼埃病最有效的外科手段之一。对7例行此手术的患者行临床及组织学研究。采用迷路后及乙状窦后联合进路切除前庭神经约3mm，标本制成l～Zpm厚神经横断切片，光镜下选择包括整个断面的超薄切片行透射电镜检查。从大约40张放大135o倍的照片重组?
Transtibial cephalactomy is the most effective surgical treatment of Meniere’s disease. Seven patients underwent this operation in clinical and histological studies. After the labyrinthine and sigmoid sinus combined approach to remove the vestibular nerve about 3mm, specimens made of l ~ Zpm thick nerve transection sections, under light microscopy, including the entire section of ultra-thin sections underwent transmission electron microscopy. From about 40 enlarged 135o times the photo reorganization?
