摘要： 目的介绍一种新的扩张法外耳再造术,应用于外耳再造术后外形不佳的患者。方法从2010年7月至2012年4月,共收治7例外耳再造术后外形不佳患者。手术分为两期:一期取出耳支架,同时行扩张器置入术。二期取出扩张器,植入耳支架。结果 7例全部成功,切口均一期愈合。术后随访6~30个月,再造耳凹凸感明显,耳廓亚单位表达清晰。结论扩张两期法修复形态不佳的再造耳,安全、稳定、创伤少,可以再造出外形良好的耳廓。

Abstract: Objective To introduce a novel two-stage expansion method for secondary total ear reconstruction. Methods From July 2010 to April 2012, 7 cases with undesirable reconstructed ears were repaired by tissue expansion method. Procedures including stage 1 （removal of previous cartilage framework, tissue expander insertion） and stage 2 （removal of tissue expander, cartilage framework insertion regarding local conditions）. Results The follow up ranged from 6 months to 2.5 years. All the eases were well recovered with good three-dimensional forms, symmetrical auriculo-cephalic angle and stable fixation. Conclusion This novel expansion method is safe, stable and less traumatic for secondary total ear reconstruction. With sufficient expanded skin flap and re-fabricated cartilage framework, lifelike appearance of reconstructed ear could be acquired without causing additional injury.
