摘要目的 探讨膨体聚四氟乙烯鼻整形术后局部感染的相关危险因素,为降低术后感染风险提供依据.方法 回顾分析923例鼻整形术中置入膨体聚四氟乙烯假体的病例,以患者的性别、年龄、术式、既往鼻部手术史、鼻部有否毛孔粗大皮脂分泌过盛的情况、是否行鼻尖表现点软骨帽移植、是否行鼻小柱支撑抬高、是否行鼻中隔软骨切取、是否行鼻中隔延伸移植、是否行鼻尖脂肪垫切除、是否行鼻翼软骨处理、是否行鼻翼缩小缩窄、术后有否严重肿胀、术后应用抗生素预防感染时间、术后鼻部有否发生毛囊炎、术后鼻部有否碰撞、术后有否鼻前庭黏膜损伤、手术切口有无愈合不良等相关危险因素,构建多因素logistic回归模型,分析导致术后感染的独立危险因素.结果 鼻部毛孔粗大皮脂分泌过盛、鼻翼软骨处理和术后鼻部碰撞均为术后感染的独立危险因素(P＜0.05).结论 鼻部毛孔粗大皮脂分泌过盛者,术后容易诱发感染;鼻翼软骨分离和部分切除以及术后鼻部碰撞,会增加术后感染风险.

abstractsObjective to investigate the risk factors of postoperative local infection in patients with polytetrafluoroethylene implant in rhinoplasty , and to provide evidence for reducing the risk of postoperative infection.Methods Retrospective analysis of 923 cases of rhinoplasty implanting ePTFE prosthesis were conducted , those related factors included were as follows : gender,age,operation,history of nasal surgery, nasal pore bulky excessive sebum secretion , cartilage cap on the tip-defining points, columella support, nasal septum cartilage harvest , extend the septum cartilage transplantation , interdomal fat pad resection, adjust the alar cartilage , reduce the ala nasi , severe postoperative swelling , prevention of postoperative infection duration , postoperative folliculitis, nasal vestibular mucosa was damaged postoperative,whether the surgical incision has abnormal healing and so on are being investigated and recorded,all of which were established as multivariate logistic regression model analysis of the risk factors for independent prognosis of postoperative infection .Results The excessive sebum of the nasal pores , adjustment of the alar cartilage and the postoperative nasal collision are the independent risk factors for postoperative infection(P＜0.05).Conclusions Patients with large nasal pores and sebum secretion are more likely to render infection after operation .Partial separation and partial nasal resection of nasal alar cartilage and postoperative nasal impact will increase postoperative risk of infection .
