船型聚四氟乙烯鼻假体在鼻整形的效果

Effect of ship-shaped expanded polytetrafluoroethylene nasal prosthesis in rhinoplasty

目的:探讨船型聚四氟乙烯鼻假体在鼻整形的效果。方法:2016年2月至2021年6月,成都高新心悦容医学美容门诊部收治要求鼻整形患者86例,男9例、女77例,年龄18~47(24±5)岁。用聚四氟乙烯雕刻成船型鼻假体结合自体软骨行鼻整形术,评估术后并发症、眉间区饱满度、眉心倒三角、鼻部多边形美学形态及患者满意度;测量并分析手术前后鼻长度、鼻尖高度、鼻额角、鼻面角。结果:86例患者术后切口均一期愈合,鼻前庭瘢痕增生8例。所有患者随访1~5年,84例获得满意的鼻部形态,2例因眉间区过于饱满,于术后半年调整降低假体高度后恢复自然。患者非常满意74例,占86%;满意10例,占11.6%。术前测量鼻长度(4.07±0.20)cm,鼻尖高度(2.66±0.36)cm,鼻额角(106.42±8.04)°,鼻面角(15.90±0.85)°,术后18个月测量鼻长度(4.23±0.20)cm,鼻尖高度(2.59±0.26)cm,鼻额角(113.69±6.34)°,鼻面角(21.57±0.78)°,其中鼻长度、鼻额角、鼻面角治疗前后比较,差异有统计学意义(t=-5.51、-5.96、-52.31,均P<0.01)。鼻尖高度差异无统计学意义(t=1.47,P=0.146)。结论:船型聚四氟乙烯鼻假体能体现鼻背美学,增加了假体稳定性及真实性,值得临床应用。

Objective To investigate the effect of ship-shaped expanded polytetrafluoroethylene(e-PTFE)nasal prosthesis in rhinoplasty.Methods From February 2016 to June 2021,86 patients,including 9 males and 77 females,aged 18-47(24±5)years old,were admitted to Chengdu High-tech Zone Xinyuerong Medical Aesthetic Clinic for cosmetic treatment of rhinoplasty.All patients underwent rhinoplasty with the application of ship-shaped e-PTFE and autologous cartilage.The postoperative complications,glabellar fullness,inverted brow triangle,nasal polygon aesthetic shape and patient satisfaction were evaluated.These data were measured and analyzed,including the nasal length,nasal tip height,nasal frontal angle and nasal facial angle before and after the operation.Results In 86 patients,the incision healed in one stage after surgery,and 8 cases had nasal vestibular scar hyperplasia.All patients were followed up for 1-5 years:84 cases obtained satisfactory nasal morphology,and 2 cases recovered naturally after adjusting and lowering the prosthesis height half a year after surgery because the interbrow area was too full.74 patients(86%)were very satisfied,10 cases(11.6%)were satisfied.The nasal length was(4.07±0.20)cm,the nasal tip height was(2.66±0.36)cm,the nasal frontal angle was(106.42±8.04)°,and the nasal face angle was(15.90±0.85)°before operation.The nasal length was(4.23±0.20)cm,the nasal tip height was(2.59±0.26)cm,the naso-frontal angle was(113.69±6.34)°,and the naso-facial angle was(21.57±0.78)°at eighteen months after operation.There were statistically significant differences in nasal length,naso-frontal angle and naso-facial angle(t=-5.51,-5.96,-52.31,P<0.01),but no statistically significant differences in nasal tip height(t=1.47,P=0.146).Conclusions The ship-shaped e-PTFE can be shaped to reflect the aesthetic of the nose dorsum,which is similar to the anatomical structure of the nose dorsum,increase the stability and authenticity of the prosthesis,and is worthy of clinical application.
