聴神経腫瘍術後顔面神経麻痺の治療—アンケート及び筋電図による検討

Treatment of the Postoperative Facial Palsy:Follow up Study by Questionaires and EMG

Ⅰ．はじめに

　聴神経腫瘍摘出手術の際合併する顔面神経麻痺は，この腫瘍が良性で長期生存例の多いこと女性に多いこと，また外見上ばかりでなく発語障害を来すこと等大きな問題である．

　もちろん近年のmicrosurgeryらの手術法の発達により顔面神経の機能を損わずに腫瘍の全摘が可能な例も増えて来ているが，顔面神経が腫瘍に埋没し不離である症例，また術中解剖学的には神経の連続が保たれているにもかかわらず顔面神経機能の回復が起らない例等，術後顔而神経麻痺患者はいまだ多い．

1) The long term results of the facial nerve paresis after removal of the acoustic neurinoma were followed up in 292 cases, operated on between 1933 and 1972. 12. at Tokyo University Hospital. Questionarires were used in 115 alive cases., including out-patient consultation in 42 and electromyographic investigation in 24.

2) Among the patients whose facial nerve was anatomically disconnected during the tumor surgery, the hypoglosso or accesso-facial nerve anastomosis is defintely helpful not only by the cosmetic but also by the functional sense: speech, mastication etc..
