摘要目的:探讨应用外侧脚支撑移植物及软骨间推进移植物矫正外侧型鼻翼退缩的临床效果。方法:回顾性分析2018年10月至2020年6月深圳美莱医疗美容医院美容外科收治的中到重度外侧型鼻翼退缩畸形患者资料。以肋软骨制备术中所需移植材料。术中充分松解卷轴区，游离下外侧软骨外侧脚并植入外侧脚支撑移植物，通过在两侧上外侧软骨和外侧脚支撑移植物之间固定软骨间推进移植物，以矫正不同程度的外侧型鼻翼退缩。手术前后鼻部测量指标以 ± s表示，采用配对 t检验进行统计学分析。 结果:共纳入32例患者，男5例，女27例，平均年龄31岁(18~47岁)；初次鼻整形23例，再次鼻整形9例；术前测量侧面观鼻翼缘最高点距鼻孔长轴的距离为(4.1±0.5) mm (3.2~5.0 mm)。患者术后即刻效果显示外侧型鼻翼退缩得到明显改善。其中20例患者获得6~18个月随访，随访时测量鼻翼缘最高点距鼻孔长轴的距离为(2.1±0.3) mm(1.5~2.8 mm),手术前后该测量值比较，差异有统计学意义( P<0.01)。1例患者术后出现轻度鼻翼外张，其余患者未见鼻翼退缩复发、鼻翼缘挛缩变形，所有患者对鼻翼退缩的矫正效果满意。 结论:应用外侧脚支撑移植物及软骨间推进移植物能有效改善外侧型鼻翼退缩畸形，其远期效果稳定，患者术后满意度较高。

abstractsObjective:To explore the surgical method and clinical effect of correcting lateral type alar retraction with intercartilaginous graft and lateral crural strut graft.Methods:A retrospective study was performed on the data of patients with moderate to severe lateral alar retraction treated in Shenzhen Mylike Medical Plastic Aesthetic Hospital from October 2018 to June 2020. During the operation, lower lateral cartilages was totally dissected and strengthened by lateral crural strut graft while scroll area was released and lengthened with intercartilaginous graft to correct lateral type alar retraction. The preoperative and postoperative distance from the nostril’s long axis to the alar rim was measured from the side view, the nasal measurements were expressed as Mean±SD, and paired t-test was used for statistical analysis. Results:A total of 32 patients were enrolled, including 5 males and 27 females, with an average age of 31 years (18-47 years). Twenty-three cases underwent primary rhinoplasty and 9 cases underwent second rhinoplasty. The preoperative data of distance from the nostril’s long axis to the alar rim was (4.1±0.5) mm (3.2-5.0 mm). The postoperative effect of nasal alar retraction defomity correction was obvious. After a follow-up period of 20 cases from 6 to 18 months, the distance from the nostril’s long axis to the alar rim was 1.5-2.8 mm [(2.1±0.3) mm on average]. Comparison of preoperative and postoperative measured values showed statistically significant difference ( P<0.01). There was 1 patient emerged complication alar flaring, and no contracture and deformation of the nasal rim occurred. All of patients were satisfied. Conclusions:The intercartilaginous graft combined with lateral crural strut graft is an effective new method for correction of lateral type alar retraction. It has stable clinical effect and high satisfaction.
