膨体联合耳郭软骨移植在降低膨体隆鼻术后鼻尖感染率的作用分析

e-PTFE prosthesisrhinoplasty combined with auricular cartilage transplantation in reduce to the infection rate of nasal tip analysis and prevention

目的:探讨膨体聚四氟乙烯在隆鼻术中的并发症及产生的原因,从而得出解决办法。方法:观察6年来1800例假体的使用方法,并进行随访,了解到e-PTFE合并感染的位置在鼻尖部的占99.8%,通过检测为金黄色葡萄球菌。结果:膨体聚四氟乙烯(e-PTFE)材料为多孔结构,而鼻尖部皮肤薄弱且毛孔粗大,增加了术后感染可能性,因其多孔状结构,感染较易在材料内扩散;而且因为局部血运较差,感染发生后,抗生素的治疗难以凑效。结论:运用e-PTFE进行隆鼻整形时,鼻尖局部采用自体耳软骨或者鼻中隔软骨替换e-PTFE,不仅杜绝了可能引起的感染;而且重塑了鼻尖形态,能取得更佳的美容效果。

Objective To evaluate the reasons of infection in augmentation rhinoplasty using e-PTFE,and the way to prevent infection.Methods 1800 patients were Observed within 6 years using the application method,and follow-up,know the position of e-PTFE amalgamative infection in the tip of the ministry of 99.8％,by examining for staphylococcus aureus.Results e-PTFE materials for porous structure,and the tip of skin weak and pore bulky,increased postoperative infection rates,because of its porous shape structure,infection in materials more easily spread within,and because blood supply is poor,infections occurred after the treatment of antibiotic almost no effect.Conclusions The usage of e-PTFE in nasal plastic can acquire favorable effects,and the tip of autologous ear cartilage or nasal septum cartilages replace e-PTFE,not only to eliminate the such causes of infection,but also to reshape the nasal tip shape.
