Analysis of related risk factors for infection after expanded polytetrafluoroethylene rhinoplasty / 中华整形外科杂志

ABSTRACT

Objective@#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.
