目的 观察耳再造患者第8肋软骨的发育情况,根据软骨的质地特点实现个性化的外耳轮美学构建.方法 2013年5月至2016年5月,对415例接受自体肋软骨耳再造患者的第8肋软骨发育情况进行分析,主要关注与外耳轮构建关系密切的长度、宽度、弹性和可塑性.在手术过程中根据上述几个方面的特点,采用4种不同的构建方案来实现外耳轮软骨合理的长度和强度,以及外耳轮与耳垂的自然衔接.结果 总结出了4种不同的第8肋软骨构建外耳轮的方案,获得了个性化的、外观自然的自体肋软骨耳支架.结论 根据患者第8肋软骨发育情况的不同选择相应的外耳轮构建方案,可以获得更为满意的再造耳外观.%Objective To observe the conditions of the eighth costal cartilage in ear reconstructed patients,and accomplish individualized aesthetic helix fabrication according to the texture and features of the cartilage.Methods From May 2013 to May 2016,the conditions of the eighth costal cartilages in 415 patients who received ear reconstruction with autogenous costal cartilage in our hospital were analyzed,during which,the length,width,flexibility,and plasticity that were closely related with the reconstruction of the helix attracted predominant attentions.During the surgery,based on the features of the abovementioned aspects,4 different methods were used to achieve reasonable length and strength of the helix as well as natural jointing between the helix and ear lobe.Results Four possible methods of using the eighth costal cartilage to reconstruct the helix were summarized and an autogenous costal cartilage framework that was individualized and with natural appearance was obtained.Conclutions According to the conditions of the eighth costal cartilage,a more satisfactory appearance of the reconstructed ear than ever before is obtained by choosing relevant helix fabrication programs.
