Autologous costal cartilage grafts remain the gold standard method for microtia reconstruction. However, reports on its long-term outcomes are limited. We present two cases with >40-year outcomes after auricular reconstruction with autologous costal cartilage. A 56 year-old woman and a 53 year-old man presented to our institution with complaints of wire exposure. In both cases, the reconstructed ear was deformed. A computerized tomography scan revealed calcification of the reconstructed costal cartilage graft framework. To our knowledge, these cases present the longest outcomes (50 and 42 years for the 56 year-old woman and 53 year-old man, respectively) of microtia reconstruction using autologous cartilage grafts. We found that ear frameworks constructed from costal cartilage tended to calcify in the long term, as in the natural course of costal cartilage. Therefore, the possibility of calcification of costal cartilage grafts should be relayed to patients and parents, and lifelong surveillance after reconstruction should be recommended.
自体肋软骨移植仍然是小耳畸形重建的金标准方法。然而，关于其长期效果的报道有限。我们展示了两例自体肋软骨耳廓重建术后超过40年的病例。一名56岁女性和一名53岁男性因导线外露问题前来我院就诊。在这两个病例中，重建的耳朵都出现了变形。计算机断层扫描显示重建的肋软骨移植框架出现钙化。据我们所知，这些病例呈现了使用自体软骨移植进行小耳畸形重建的最长随访结果（56岁女性和53岁男性分别为50年和42年）。我们发现，如同肋软骨的自然病程一样，由肋软骨构建的耳框架长期来看有钙化倾向。因此，应向患者及家长传达肋软骨移植钙化的可能性，并建议重建后进行终身监测。
