Galen氏袢是喉上神经和喉返神经之间的吻合点,其解剖及生理仍不清楚。据传统解剖记载,人类有30～60％存在此袢。由于以往的解剖均在防腐尸体标本上进行,所以不可能分离出很细的神经末梢。本文对来自30个病人的47个新鲜半喉进行显微解剖,解剖过程标本始终保持湿润,对有疑问的神经组织进行组织学检查加以确定。方法:从后面正中切开下咽及 Galen’s fistula is an anastomosis between the laryngeal nerve and the recurrent laryngeal nerve, and its anatomy and physiology remain unclear. According to traditional anatomical records, humans have 30 ~ 60% of this 袢. Due to the previous anatomy were preserved on the corpse specimens, it is impossible to isolate very fine nerve endings. In this article, 47 fresh hemifacients from 30 patients were dissected microscopically and the anatomical specimens remained moist. Histological examination of the suspected neurological tissue was performed. Method: From the back of the middle cut under the swallowing and
