扩张器扩张无需植皮在耳廓再造术中的应用

目的探讨一期采用扩张器扩张、二期无需植皮进行耳廓再造,并总结其优缺点。方法 2008年1月-2010年12月收住30例先天性小耳畸形患者,一期选择80ml肾形扩张器埋置于畸形小耳后外方乳突区,术后定量间断注水,每次注水量为总量的10%-20%,注水完毕后持续扩张2个月,二期取出扩张器,切取、移植、雕塑肋软骨作为耳支架,进行固定后,将扩张的皮瓣完全覆盖在支架的前、后、上、下部。同时与2008年以前选择50ml肾形扩张器的30例小耳畸形患者进行对照。结果选择50ml扩张器组,一期手术后出现1例血肿,二期术后出现1例移植皮片部分坏死,软骨支架外露,经二次手术修复。术后3个月随访,观察再造耳轮及结构欠清晰,耳后瘢痕较明显,胸部切口瘢痕增生明显。选择80ml扩张器的患者,一期手术后出现2例血肿,二期手术耳后颅侧壁及支架上方无需另取皮片移植,无感染及软骨外露等并发症出现,胸部切口愈合良好。术后半年随访,再造耳结构清晰、逼真,耳前、后无皮瓣与移植皮片相互拼接所形成的瘢痕,胸部取肋软骨的切口因缝合时张力较小,故瘢痕明显小于50ml扩张器组,缺点是个别患者再造耳上后部可见少许毛发生长。结论选择80ml肾形扩张器较选择50ml扩张器在耳廓再造一期手术中可扩张出充足的皮肤组织,在二期手术中完全覆盖耳支架,无需植皮,无植皮遗留的瘢痕,胸部取肋软骨处切口瘢痕明显减小,但一期手术由于剥离范围增大,血肿等并发症的发生率可能提高。

Dilator expansion without skin grafting in the reconstruction of the auricle

Objective After an expansion by soft tissue expander,the second procedure without skin grafting for ear reconstruction,to summarize their advantages and disadvantages.Methods From January 2008 to December 2010 admitted to the 30 cases of congenital microtia patients,a kidney-shaped expander selection 80ml embedded in a small defects foreign mastoid area behind the ear,after quantitative intermittent water injection,water injection time For the 10%-20% of the total,the continued expansion of water after 2 mo...
