摘　　要：目的探讨耳廓复合组织块游离移植成活的影响因素。方法对27块耳廓复合组织移植修复鼻翼缺损的病例进行分析。结果早期常规手术方法移植13例,最大宽径1.5 cm,最小宽径0.8 cm,3例部分坏死;改进手术方法移植14例最大宽径2.5 cm,最小宽径1.2 cm,全部成活。结论增加复合组织块与鼻部受区接触面积是提高移植之耳郭复合组织块成活的关键。保留真皮下和软骨膜血管网及术后丹参应用有助于增加移植块远端成活能力。Objective To explore influence factors on survival of auricle composite tissue graft. Methods Analysis was carried in 27 cases repaired defect of alae nosi with auricle composite grafts. Results Among 13 cases used routine operation method, the width of the composite grafts ranged from 0.8 cm to 1.5 cm,the graft partly necrosed 3 case, Among 14 cases used improved operation method, the width ranged from 1.2 cm to 2.5 cm,all graft survived. Conclusion Increasing the contact area of the auricle composite graft and recipient site of nosi are the keys of the survival of auricle composite graft. Retaining subdermal vascular network and cartilage membrane vascular network and using danshen after operation contribute to survival of distal part of graft.
