虽然目前已公认喉返神经分布于同侧除环甲肌以外之所有喉内肌肉,喉部粘膜感觉神经来自喉上神经之喉内支与喉返神经之分支。然而对喉上神经是否有一分支分布于杓间肌的内收肌始终存在着争论。作者首先回顾了过去有关喉部肌肉及粘膜感觉神经分布之各种意见,然后描述在6—25倍手术显微镜下对12例22侧新鲜尸检喉部标本进行的显微解剖和6例3—4个月胎儿喉组织切片的观察结果:(1)喉上神经仅有穿通支经过杓间肌分布于喉后部粘膜,并无分支终止于杓间肌。(2)喉上神经的最下支向下越过环杓后肌与喉返神经感觉支相吻合,形成Galeni攀。
Although it has now been accepted that the recurrent laryngeal nerve is located in all the laryngeal muscles other than the cricothyroid in the ipsilateral, the laryngeal mucosal sensory nerve is derived from the branch of the laryngeal branch and the recurrent laryngeal nerve of the laryngeal nerve. However, there remains a debate about whether there is a branch of the laryngeal nerve distributed in the adductor muscle of the interlayer. The authors first reviewed various past opinions on the distribution of sensory nerves in the laryngeal muscles and mucosa and then described the microdissection of 12 cases of fresh necropsy laryngeal specimens in 12 cases under 6-25 times the surgical microscope and 6 Month fetal laryngeal tissue sections of the observation: (1) laryngeal nerve only through the intercostobrasis distribution in the posterior laryngeal mucosa, there is no branch in the intercostobal muscle. (2) The lowermost branch of the laryngeal nerve goes down over the ciliate and the recurrent laryngeal nerve sensory branch to form a Galeni climb.
