摘要： 目的探讨数字化技术辅助下选择性采伐肋软骨以完成耳支架制备的可行性。方法 2016年10月至2017年8月,针对20例先天性小耳畸形患者肋软骨及耳廓的不同生理特征,在数字化技术辅助下,分别采伐不同数量的肋软骨,用于耳支架的雕刻以完成全耳郭再造。结果 20例患者均顺利完成手术,术后随访平均1.3年,再造耳形态令人满意,切口均一期愈合,无皮肤软组织坏死,无软骨移位。结论将数字化技术有效地应用于肋软骨采伐、耳支架的设计与雕刻,可提高自体肋软骨采伐的精确度,并辅助肋软骨的设计、切割,实现耳再造支架的个性化雕刻,是一种安全可靠的方法。

Abstract: Objective To explore the feasibility of using digital technology to assist in selective harvesting of costal cartilage and the preparation of ear scaffolds.Methods From October 2016 to August 2017,20 microtia patients accepted ear reconstruction.According to the different physiological characteristics of the costal cartilage and auricle,different number of the costal cartilages were harvested by digital technology navigation for ear reconstruction.Results All the 20 patients completed the operation successfully.The postoperative follow-up was 1.3 years on average.The shape of the reconstructed ear was satisfactory,the incision was uniform,no skin soft tissue necrosis and no cartilage displacement were observed.Conclusion It is a safe and reliable method to apply digital technology to the cutting of costal cartilage,to the design and engraving of the ear.It can improve the precision of autogenous rib cartilage cutting,assist the design and cutting of costal cartilage,and realize the personalized engraving of the ear support.
