摘要
耳廓复合组织瓣为修复鼻翼缺损的首选供区。以往用游移植法，其高度超过１ｃｍ时易致坏死失败。笔者根据眶上动脉与颞浅动脉额支之间有恒定吻合支的特点，并经尸体由颈内动脉灌注染料行解剖观察，证明：颈内动脉血流，可自眶上动脉→眶上动脉与颞浅动脉额支的吻合支→颞浅动脉→颞浅动脉耳支而营养耳廓。从而设计了以眶上动脉为蒂的岛状耳廓复合组织瓣，经皮下隧道转移至鼻翼缺损区，Ⅰ期修复鼻翼缺损的新方法。１９９０年以来，我科用本法治疗较大鼻翼缺损者６例，最大面积为３．８ｃｍ×２．８ｃｍ，最小为２．５ｃｍ×２ｃｍ，均获得良好效果。
The auricular composite tissue is a prior option to reconstruct a nasal ala defect. The auricular composite tissue grafts often fail to survive when the height is greater than 1cm. We injected the dyestuff into the internal carotid artery and observed the anastomotic branches between the supraorbital artery and the superficial temporal artery. We found the dyestuff could get into the supraorbital artery, then got into the auriclar branches of the superficial temporal artery through the anastomotic branches. According to this finding, we designed a reversal flow composite auricular island flap based on the supraorbital artery. We have successfully reconstructed 6 cases of nasal ala defects in one stage with this flap since 1990. The dimension of the flaps were 2.5cm×2cm to 3.8cm×2.8cm and the results were satisfactory.
