摘要： 目的 探讨运用肋软骨三维形态测量技术,指导成人先天性小耳畸形耳廓再造术中肋软骨采伐的可行性。方法自2014年1月至2014年12月,对46例成年先天性小耳畸形患者,术前运用三维CT分别测量第6、7、8肋软骨的三维形态和CT值,并根据测量结果,选择雕刻耳支架的肋软骨量。所有患者术后随访4~12个月。结果 第6、7、8肋软骨双侧不对称20例(43.48%),肋软骨钙化明显者14例(30.43%),肋软骨采伐术中折断1例(2.17%),术后胸廓轻度畸形2例(4.35%)。结论 术前肋软骨三位形态的测量可以准确评估肋软骨情况,有助于提高成人先天性小耳畸形患者耳廓再造术中,肋软骨采伐的效率及质量,并降低术后并发症。

Abstract: Objective To study the feasibility of 3-dimensional rib cartilage CT measurement on guiding rib cartilage harvest of adult patients with congenital microtia for auricular reconstruction. Methods From Janual7 2014 to December 2014, 46 adult patients suffering congenital microtia were included in this study. The measurements of 3D CT reconstruction on the sixth, seventh, eighth rib cartilage were finished before surgery. The amounts of rib cartilage for carving ear cartilage scaffold were determined by the measurements. All patients were followed up for 4 months to 1 year. Results There were 20 cases （43.48%） with bilateral asymmetry of the sixth, seventh, eighth rib cartilage. Meanwhile, there were 14 patients （30.43%） with significantly calcified rib cartilages. One case （2.17%） suffered rib cartilage fracture during harvesting rib cartilage. And mild chest deformity was observed in 2 cases （4.35%） after surgery. Conclusion Harvest of rib cartilage for adult ear reconstruction can be promoted by preoperative measurements of 3D rib cartilage morphology. Meanwhile, postoperative complications could be decreased.
