目的：探讨耳甲腔型小耳畸形的残耳组织在耳再造术中的合理应用方法。方法2011年8月-2013年6月，我科对85例耳甲腔型小耳患者(88只耳)行扩张器法耳再造术。一期行耳后扩张器植入和残耳耳垂旷置。二期取自体肋软骨做扩张皮瓣耳廓再造术，并利用旷置的耳垂行转位术与再造耳支架衔接。三期将剩余的残耳组织做再造耳的局部修整。结果随访6～15个月，再造耳立体感强，以残耳形成的耳垂外形丰满，覆盖于耳甲腔处的残耳耳甲皮瓣色泽自然，垫于耳支架后方的残耳软骨弹性好，患者及家属均满意。结论耳甲腔型小耳畸形的残耳组织量丰富，在耳再造各期手术中的综合利用方法值得推广。

Objective To study the utility of existing residual ear structures in auricular reconstruction for concha-type microtia. Methods From August 2011 to July 2013, 85 patients with microtia (88 ears) were treated with staged auricle recon-struction treatment using tissue expander. The first stage involved placement of a tissue expander. Reconstruction using the ex-panded skin flap and autogenous cartilage framework was performed in the second stage, completed with linking the existing earlobe to the reconstructed-ear scaffold. In the third stage, unused residual ear structures were exploited to improve final mor-phology of the reconstructed-ear. Results The patients were followed up for 3 months to 2 years with satisfactory aesthetic re-sults. Earlobes appeared natural, the residual flap covering the concha survived well, and the residual auricular cartilage mat-ted behind the scaffold exhibited good elasticity. Conclusion Residual auricular tissues in concha-type microtia is easily available and can be very useful in staged auricle reconstruction.
