Ear reconstruction is one of the most challenging surgeries faced by the reconstructive surgeon. Currently, the use of autogenous costal cartilage is still best practice for microtia reconstruction. However, the relative deficiency of thin skin for coverage of the cartilage framework remains a limiting factor. Since 1994, we have used tissue expander in the mastoid area and innovated a technique to fabricate cartilage framework. All these innovations may solve the deficiency of the skin and improve cartilaginous framework definition. In conclusion, tissue expander offers a non-hairbearing, thin, well-vascularised skin to envelope an erect, contour-accentuated framework. Most patients with microtia are satisfied with their ear reconstruction.
耳部重建是整形外科医生面临的最具挑战性的手术之一。目前，自体肋软骨的使用仍是小耳畸形重建的最佳方法。然而，用于覆盖软骨支架的薄皮肤相对不足仍然是一个限制因素。自1994年以来，我们在乳突区使用组织扩张器，并创新了一种制造软骨支架的技术。所有这些创新可能解决皮肤不足的问题，并改善软骨支架的清晰度。总之，组织扩张器提供了一块无毛、薄且血运良好的皮肤来包裹一个直立的、轮廓突出的支架。大多数小耳畸形患者对他们的耳部重建感到满意。
