摘要目的:评估保留软骨膜的肋软骨皮质在鼻尖成形中的优点。方法:2017年7月至2018年7月，于郑州美莱医疗美容医院整形外科行肋软骨综合鼻整形的女性患者618例，年龄18～52(27±6)岁。根据鼻尖修饰移植物不同分为保留肋软骨膜皮质组( n＝276)与单纯肋软骨皮质组( n＝342)。术后1个月、12个月随访拍照对比两组鼻尖移位显形情况，分析两者优缺点。 结果:保留肋软骨膜皮质组移位发生率为3.6%，单纯肋软骨皮质组移位发生率为7.9%，保留肋软骨膜皮质组移位率低于单纯肋软骨皮质组(χ 2＝4.95, P<0.05)。保留肋软骨膜皮质组显形发生率为4.7%，单纯肋软骨皮质组显形发生率为9.1%，保留肋软骨皮质组显形率低于单纯肋软骨皮质组(χ 2＝4.38, P<0.05)。将保留软骨膜的皮质用于鼻尖成形术，术后鼻尖突出度良好，远期不易变形、移位及显形。 结论:保留肋软骨膜的肋软骨皮质在鼻尖成形术中可获得良好的鼻尖突出度及稳定的旋转度，是一种较好鼻尖塑形材料，值得临床使用。

abstractsObjective:To evaluate the advantages of cortical perichondrium retention of costal cartilage in tip plasty.Methods:A total of 618 female cases were retrospectively analyzed from July 2017 to July 2018 in Zhengzhou Meilai Medical Beauty Hospital that underwent comprehensive line of rib cartilage rhinoplasty for beauty, aged 18-52 years with mean 27±6 years. According to different modification graft used in plasty, the cases were divided into reserve costal perichondrium cortex group (experimental group) and simple rib cartilage cortex group (control group). Statistical analyses were carried out 1 month and 12 months after operation. The tip displacement visualization was compared between the two groups and the advantages and disadvantages were evaluated in both.Results:After the surgery of the 618 patients, the rate of displacement in the experimental group was 3.6%, and that in the control group was 7.9% (χ 2=4.95, P<0.05). The rate of the implant exposure in the experimental group was 4.7%, and that in the control group was 9.1% (χ 2=4.38, P<0.05). The reserve costal perichondrium cortex used in the nasoplasty kept the prominent and stable nasal tip after the operation, and longterm follow-up showed there were no displacement and deformation occured in the patients. Conclusions:The application of costal cartilaginous cortex retaining costal perichondrium in tip plasty can obtain good nasal tip protrusion and stable rotation. It is an ideal nasal tip shaping material and worthy of clinical application.
