自体肋软骨+medpor耳基复合耳廓支架一期全耳再造

Autogenous costal cartilage with Medpor:a compound auricular framework applied to one-stage total ear reconstruction

目的 介绍一种制作简便 ,立体感强 ,不易吸收变形 ,柔韧性良好的复合耳廓支架。方法 采用外形细圆 ,有一定拱形弧度的自体第 9肋软骨制作外耳轮 ,以medpor做耳基形成复合耳廓支架 ,依照健侧耳廓模型塑形固定 ,覆盖颞浅筋膜及皮片 ,行一期全耳再造术。结果 临床应用 9例均效果满意 ,再造耳廓形态自然 ,立体感强 ,质感柔韧 ,术后随访 3个月～ 2年无一例支架外露或吸收变形。结论 自体肋软骨 +medpor耳基复合耳廓支架综合了自体肋软骨及medpor耳支架二者优点 ,弥补了肋软骨耳支架易于吸收变形、雕刻塑形困难 ,而medpor外耳轮偏硬 ,容易出现支架外露等各自不足 ,具有实用性强、操作简单、创伤小和并发症少等优点 ,是目前全耳再造术中较为理想的耳廓支架。

Objective To introduce a compound external ear framework characterized by few complications.simplicity and very low rate of implant exposure or absorption.Methods Acompound auricular framework,being composed of the ninth autogenous costal cartilage as ear rim and Medpor ear base,was used in one-stage total ear reconstruction.All patients were followed up postoperatively.Results Nine cases have been performed clinically using this compound framework and all of them achieved satisfactory efficacies.The reforged ears looked natural and achieved superior cosmesis,and none of them experienced ear rim fracture or implant exposure or distortion.Conclusion This compound auricular framework has advantages of practicability,simplicity and minimal complications.It may be an ideal framework for the reconstruction of total external ear at present.
