目的:与传统假体隆鼻术比较，分析自体肋软骨颗粒游离移植隆鼻术患者的效果。方法:2016年3月至2018年5月，河南省省立医院烧伤整形科美容中心收治72例要求行隆鼻术女性患者。采用随机数字表法将患者分为两组，观察组36例，年龄(26.82±5.61)岁，采用自体肋软骨颗粒游离移植术；对照组36例，年龄(25.02±6.93)岁，用假体隆鼻术。观察患者鼻面角、鼻额角、鼻唇角、鼻小柱上唇角、鼻尖突出度，并统计患者满意度。结果:两组术后均未发现感染、隆鼻部位变形、假体外露、折断、歪斜等并发症。两组隆鼻术前测量面部角度各数值差异无统计学意义(n P>0.05)，观察组术后鼻额角相比术前明显增大(n P0.05)，两组鼻面角、鼻唇角、鼻小柱上唇角、鼻尖突出度在手术前后差异均无统计学意义(均n P>0.05)。观察组患者满意度(100.00%)明显优于对照组(88.89%)，两组差异有统计学意义(n P0.05). The nasal frontal angle in the observation group increased significantly compared with that before the operation (n P0.05). Nose angle, nasolabial angle, upper lip angle of nasal column, and nose tip protrusion of the two groups had no difference before and after surgery (n P>0.05). The total satisfactory rate of the observation group (100.00%) was significantly better than that of the control group (88.89%), and the difference between the two groups was statistically significant (n P<0.05). No complications such as infection, deformation of the rhinoplasty site, exposure of the prosthesis, breakage, and skew were found in both groups.n Conclusions:The closed approach of autologous costal cartilage granule transplantation rhinoplasty surgery is a composite application of the patient's autologous tissue, which has the advantages of simplicity, safety and high efficiency. It can effectively improve the clinical symptoms of the patients. The postoperative satisfaction and nasal psychological identity are high, without the complications of artificial implants. Therefore, it is recommended to prefer rhinoplasty with autologous costal cartilage particles free transplantation according to the actual condition.
