摘要:  

目的：通过3D打印辅助自体肋软骨隆鼻术更好地重建唇裂修复后的鼻形，特别是对鼻根填充需求的患者。方法：2016年7月至2021年11月，20例唇裂修复后继发鼻畸形且需鼻根填充的患者接受手术治疗。10例采用3D打印辅助自体肋软骨隆鼻术，10例采用传统方法。根据鼻畸形特点，雕刻自体肋软骨并植入鼻背。结果：3D打印辅助自体肋软骨隆鼻术治疗唇裂后继发鼻畸形，切口愈合良好，胸软骨供区无并发症。鼻形满意，鼻尖高度和形状及双侧鼻孔大小基本对称，鼻小柱延长，原鼻尖扁平、鼻翼塌陷改善满意，鼻唇角接近正常。结论：3D打印辅助自体肋软骨隆鼻术是唇裂后继发鼻畸形的理想治疗方法。  

Abstract:

Objective: to better reconstruct the nasal shape after cleft lip repair with 3D printing assisted autologous costal cartilage augmentation rhinoplasty, especially for patients with radix augmentation needs. Method: 20 patients with nasal deformity secondary to cleft lip repair and radix augmentation needs had received surgical treatment from July 2016 to November 2021. A total of 10 cases were treated with autologous costal cartilage augmentation rhinoplasty for nasal deformity after cleft lip repair, and 10 cases were treated with the help of 3D printing. According to the characteristics of nasal deformity, autologous costal cartilage was carved and implanted into the nose back. Results: 3D printing assisted autologous costal cartilage augmentation in the treatment of nasal deformity after cleft lip repair, the incision healed well, and there were no complications in the thoracic cartilage donor area. The shape of the nose is satisfactory, the height and shape of the nose tip and the size of both nostrils are mostly symmetrical, the nasal columella is elongated, the original nose tip is flat, the collapse of the nose wing is satisfactory, and the nose lip angle is close to normal. Conclusions: 3D printing assisted autologous costal cartilage augmentation is an ideal treatment for nasal deformity after cleft lip repair.
