Analysis of Factors Affecting Postoperative Drainage After Comprehensive Rhinoplasty

This study aimed to explore and analyze the factors influencing the drainage volume after comprehensive rhinoplasty. The clinical data of 102 patients who underwent comprehensive rhinoplasty at Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine from August 2019 to August 2021 were retrospectively analyzed. The effects of age, sex, body mass index, whether an osteotomy was performed, and whether a nasal septum flap was obtained on the indwelling time of the drainage tube after the operation were analyzed by single factor analysis and multiple logistic regression analysis. Age, body mass index, whether it was a primary rhinoplasty, whether an osteotomy was performed, and whether a nasal septum flap was obtained were the influencing factors for drainage time after augmentation rhinoplasty ( P <0.05). Sex had little effect on the drainage time after comprehensive rhinoplasty ( P >0.05). Body mass index, whether an osteotomy was performed and whether a nasal septum flap was obtained were the independent influencing factors for the postoperative drainage time ( P <0.05). For patients with multiple independent influencing factors, individualized management during the perioperative period should be promoted, and reasonable treatment strategies should be formulated, so as to reduce the indwelling time of the drainage tube after the operation.
