Autologous conchal cartilage is becoming increasingly popular as a source of material for secondary reconstruction. The aim of this study was to verify the effect of dichotomous autologous conchal cartilage transplantation in the treatment of unilateral cleft lip nasal deformity.
Eighteen patients (10 males and 8 females) with unilateral cleft lip nasal deformity treated from August 2018 to August 2019 were selected for the study. The cut C-shaped conchal cartilage was trimmed into a strip shape and a shield shape and transplanted into the alar cartilage and the tip of the nose, respectively. The effect of the operation was evaluated in terms of patient satisfaction, two-dimensional linear quantitative results, and three-dimensional spatial differences after the operation.
During follow-up from 6 months to 2 years, the nasal appearance of 18 patients was significantly improved. The postoperative patient satisfaction survey revealed more than 93% satisfaction for each research index. Two-dimensional linear quantitative analysis revealed that the height of the nasal columella and nostril was significantly increased and that the nasal base and breadth were significantly decreased after the operation. Evaluation of the three-dimensional spatial difference between the unaffected side and the affected side before and after the operation revealed a significant decrease in the difference in the soft tissue volume between the unaffected side and the affected side (P < 0.05).
Dichotomous autologous conchal cartilage transplantation is an ideal method for the treatment of unilateral cleft lip nasal deformity.
自体耳软骨作为二次重建的材料越来越受欢迎。本研究旨在验证二分法自体耳软骨移植治疗单侧唇裂鼻畸形的效果。
选择 2018 年 8 月至 2019 年 8 月收治的 18 例单侧唇裂鼻畸形患者（男 10 例，女 8 例）进行研究。将切取的 C 形耳软骨修剪成条状和盾状，分别移植到鼻翼软骨和鼻尖。根据患者满意度、术后二维线性定量结果和三维空间差异评估手术效果。
18 例患者随访 6 个月至 2 年，鼻部外观明显改善。术后患者满意度调查显示，每个研究指标的满意度均超过 93%。二维线性定量分析显示，术后鼻小柱和鼻孔高度明显增加，鼻底和宽度明显减小。术前和术后健患侧三维空间差异评估显示，健患侧软组织体积差异显著减小（P < 0.05）。
二分法自体耳软骨移植是治疗单侧唇裂鼻畸形的理想方法。
