扩张法耳再造术后支架外露及其防治

The prevention and treatment for the framework exposure following auricular reconstruction

目的通过对全耳再造术后支架外露的部位、时间及原因的统计分析,探讨预防及处理支架外露的方法。方法对32例支架外露的患者进行回顾性分析统计,采用带颞浅动、静脉的皮下组织筋膜瓣转移加中厚植皮、带颞浅动脉的耳前头皮瓣及局部皮瓣转移等方法修复支架外露部位。结果全耳再造术后支架外露多出现在术后一个月内,以耳轮后上缘交界处的外露多见,其次是耳轮缘再造耳与残耳连接处。外露部位张力较大,包扎时压力过大,软骨支架边缘不平滑及扩张皮瓣受损是支架外露的原因。经过上述方法处理,所有采用软骨支架行耳再造的患者伤口均一期愈合,皮瓣及皮片全部成活,未出现再造耳感染及支架再次外露的情况,效果满意。采用Medpor支架行耳再造者6例,其中有2例经两次修复仍出现支架外露,将支架取出后创面愈合,其余4例均一期愈合。结论术中需要特别注意容易出现支架外露部位的处理,术后1月内应对再造耳进行严密的观察,出现支架外露后因地制宜地采用合适的方法进行修复,可以很好地预防并处理再造耳支架的外露。Medpor支架外露的发生率高,处理困难,在肋软骨未钙化的患者中多不主张采用该材料。

Objective By analysis of the region,postoperative period and causality of framework exposure after auricular reconstruction,we want to find the methods for its prevention and treatment.Methods A retrospective analysis was performed for thirty-two patients who suffered from framework exposure after auricular reconstruction.The subcutaneous tissue and temporal superficial fascia flaps combining with split skin graft transplantation,temporal superficial scalp flaps,and neighboring flaps were used in the treatm...
