摘　　要：目的　寻求耳廓复合组织片游离移植时面积受限之解决方法。方法于 2 9具成人灌注尸体标本 ,进行额、鼻、颞部血管解剖观测 ,并进行临床实践。结果　颈内动脉的血流 ,可自滑车上动脉、眶上动脉→前额动脉吻合网→颞浅动脉额支→颞浅动脉主干→颞浅动脉耳支而营养耳廓。根据解剖结果 ,可设计以滑车上、眶上动脉为血管蒂的跨区供血的反流轴型耳廓复合组织岛状瓣 ,修复大面积鼻翼缺损 ,临床上已应用 16例 ,取得满意效果。结论　来自颈内动脉的血液可经前额动脉吻合网进入颈外动脉分布的耳廓及耳前、耳后组织 ,提供血供 ,可据以设计岛状耳廓复合组织瓣 ,修复大面积鼻翼缺损。Objective To evaluate a retro-grade auricular flap for repairing large alar defects. Methods Twenty-nine adult cadavers were anatomically used for vascular investigation of the frontal, nasal and temporal regions by injecting a dye into the main vessels. Based on the anatomical study in these regions, a retro-grade auricular flap was designed for repairing alar defects in 16 patients. Results The blood supply of the auricle could be nourished by the inner carotid artery system from the supratrachlear artery and supraorbital artery through the frontal arterial anastomotical network into the frontal branch of the superficial temporal artery. It is then passing the main trunk of the superficial temporal artery into the ear area through the auricular branches of the superficial temporal artery. The retro-grade auricular island flap could be formed by basing the supratrachlear artery and the supraorbital artery through the vascular network between the superficial temporal artery and the supratrachlear artery or the supraorbital artery. Sixteen patients with large alar defects and half-sized nasal defects were successfully repaired by this technique. Conclusions The retro-grade auricular island flap,based on the inner carotid artery system, could be a good and safe flap for repairing a large alar defect or half-sized nasal reconstruction. ;
