了解耳前面的血液供应,对于耳成形和耳廓组织瓣移植术十分重要。作者解剖20具尸体耳廓。通过注射乳汁溶液,以明确耳前面的血供情况,发现耳前面存在两组动脉网,三角窝-舟状窝网和耳甲网(图1),两者最终在对耳轮上沟通。三角窝-舟状窝网起自颞浅动脉(STA)耳上支的一个分支和耳后动脉的分支,后者穿过耳垂、三角窝,并越过耳轮缘达耳前面。耳甲网由2～ Knowing the blood supply to the front of the ear is very important for ear formation and auricular tissue flap transplantation. The author dissected 20 corpses ear. By injecting a milk solution to clarify the blood supply to the front of the ear, two sets of arterial, triangular-shaped boat nests, and velcro (Figure 1) were found in front of the ears, both of which eventually communicated to the ear. Triangular fossa - The fossa nest starts from a branch of the superior branch of the temporal superficial artery (STA) and a branch of the posterior branch of the posterior artery, which passes through the lobe, the trigone, and beyond the front of the ear.
