摘　　要：目的为耳廓离断再植提供显微解剖学资料。方法2016年3月至2019年3月,采用25例新鲜成人头部标本,其中20例经颈外动脉灌注ABS充填剂并腐蚀处理制成铸型标本,5例灌注红色乳胶后进行解剖,观察耳后动脉(PAA)和颞浅动脉(STA)耳廓支的发出部位、走行、分布和吻合特点。结果耳廓的血供来源于PAA和STA的耳廓支。PAA发出的耳廓支有耳后上、中、下支,分布于耳廓后面,部分分支穿过耳廓软骨或跨越耳廓外缘,至耳廓前面与STA的耳廓支吻合。STA发出耳前上、中、下支,分布于耳廓前面上、下部和中部内侧。各耳廓支起始部的直径为0.2~0.8 mm。耳廓约80%的血供来自PAA,约20%来自STA。结论PAA耳廓支的血供对耳廓离断再植成活起重要作用,应首先选择,其次考虑STA耳廓支。Objective To provide the anatomical information for auricle replantation.Methods From March,2016 to March,2019,a total of 25 fresh adult cadaveric head were used,20 of these specimens were perfused with plastic and eroded to be vascular cast mold,5 specimens perfused with red latex for anatomy,then observed the origin,course,diameter and arteries anastomose between branches of the posterior auricular artery(PAA)and superficial temporal artery(STA).Results The main blood supply to the auricle were auricle branches of PAA and STA.The auricle branches of PAA and STA both divided into superior,intermedius and inferior branches,and distributed in the auricle posterior surface and anterior surface,respectively.The auricle branches of PAA running across ear cartilage,distributed in the anterior surface,and anastomosed with auricle branches of STA.The diameters of these branches at the initiating portion were 0.2-0.8 mm.Eighty percent of blood supply to earlobe was from the inferior branches of PAA,and 20%from the STA.Conclusion The auricle branches of PAA played an important role to the auricle replantation.The auricle branches of PAA should be the firstly selected vessle in operation,and the auricle branches of STA be the second choice.
