Major difficulties in laryngeal reconstruction are due to laryngeal nerves. A study was conducted of 100 larynges from fresh subjects after vascular injection. Vascularization of superior laryngeal nerves is derived essentially from superior laryngeal and ascending pharyngeal arteries. Inferior laryngeal nerves obtain their vascular supply from inferior thyroid and main carotid arteries. Histomorphometric study of laryngeal nerves used semi-automatic techniques: microscope, numerical table, computer, printer. The number of fibers per nerve varied between 511 and 2.244, the number of nerve fasculi between 3 and 14, and the diameter of myelinated fibers between 2 and 12 micron. Fibers of left inferior laryngeal nerve had a mean diameter (8.9 to 10.2) greater than those of right inferior laryngeal nerve (5.1 to 5.2 micron). Nerve tissue represented 60% to 66% of total. The left recurrent was longer than right nerve but had larger fibers providing more rapid conduction. Cartography of laryngeal nerves from 2 mm serial sections confirmed their plexis structure, this study providing new and objective precisions on laryngeal nerve structure.
喉重建的主要困难与喉神经有关。对100例新鲜尸体经血管灌注后的喉部进行了研究。喉上神经的血供主要来自喉上动脉和咽升动脉。喉下神经的血供来自甲状腺下动脉和颈总动脉。对喉神经进行组织形态计量学研究时采用了半自动技术：显微镜、数字表、计算机、打印机。每条神经的纤维数量在511至2244之间，神经束数量在3至14之间，有髓纤维直径在2至12微米之间。左喉下神经纤维的平均直径（8.9至10.2）大于右喉下神经纤维（5.1至5.2微米）。神经组织占总体的60%至66%。左喉返神经比右喉返神经长，但纤维更粗，传导速度更快。对2毫米连续切片的喉神经进行绘图证实了它们的丛状结构，这项研究为喉神经结构提供了新的客观精确数据。
