The arterial anatomy of the ear was investigated using seven auricles of seven fresh cadavers that had been injected systematically with a lead oxide-gelatin mixture. The blood supplies of the upper portions of the helix, antihelix and scapha, triangular fossa, tragus and lobule were from the branches of the superficial temporal artery. The blood supplies of the chonca, the middle and lower portions of the helix and scapha, the lower part of the antihelix and most of the posterior auricular surface except the lobule were from the branches of the posterior auricular artery. The posterior auricular artery found to be the dominant blood supply for the ear.
使用七具新鲜尸体的七个耳廓，通过系统注射氧化铅 - 明胶混合物来研究耳部的动脉解剖结构。耳轮、对耳轮和耳舟、三角窝、耳屏和耳垂上部的血液供应来自颞浅动脉的分支。耳甲、耳轮和耳舟的中下部、对耳轮下部以及除耳垂外的大部分耳后表面的血液供应来自耳后动脉的分支。发现耳后动脉是耳部的主要血液供应。
