摘要
目的探讨应用耳后乳突区皮管转移修复外伤性耳轮部分缺损的经验及效果。方法依据耳轮缺损的部位及范围，在耳后乳突区预构皮管，皮管长度与缺损长度比例为1．2～1．5：1，形成皮管的皮瓣长宽比例为3～4：1。手术全程分3期：一期预构皮管，2～3周后二期手术将皮管一端断蒂转移，再过2～3周后三期手术将皮管完全转移修复缺损。结果1998年1月至2006年6月．共收治外伤性耳轮部分缺损患者47例，年龄16～58岁，平均27岁，缺损时间1个月～15年。术后所有病例移植皮管全部成活，无血运障碍、感染及坏死等并发症发生。随访时间2个月～5年,效果满意。结论耳后乳突区皮管转移修复外伤性耳轮部分缺损具有术式简单、移植成活率高、形态逼真、供区隐蔽、痛苦小等优点，是修复外伤性耳轮部分缺损的理想术式。
Objective To investigate the effect of postauricular tube flap for repairing traumatic partial helical defect. Methods The tube flaps were designed according to the site and size of helical defects, The length of tube flaps was 1,2 - 1,5 times as the length of the defects. The length-to-width ratio of tube flap was 3 4： 1. The proceduces required three stages for completion： ① fabrication of tube flap; ② 2 ～3 weeks later, division of one pedicle and insetting the flap; ③ 2 ～ 3 weeks later, complete division of pedicle and repairing the defects. Results From January 1998 to June 2006, 47 cases of traumatic partial helical defects were treated with postauricular tube flaps. All the tube flaps survived completely with no vascular disturbance, infection or necrosis, The patients were followed up for 2 months to five years with satisfactory results. Conclusions Postauricular tube flap is a reliable and simple procedure for traumatic partial helical defects with good cosmetic result and less donor site morbidity.
