Background:
Free flap reconstruction of head and neck defects is routinely performed with a high success rate nowadays. However, postoperative complications are still commonly observed. The aim of this study is to investigate risk factors correlated with postoperative complications following free flap reconstruction of head and neck defects.
Methods:
A retrospective study of all patients undergoing free flap reconstruction of head and neck defects between January 2018 and January 2020 at Sun Yat-sen Memorial Hospita, Guangzhou, China was performed. Preoperative, intraoperative, and postoperative data were collected retrospectively. The primary outcome variables were postoperative complications, which were divided into medical and surgical complications. All patients were grouped by either complications or no complications. Univariate and multivariate logistic regression models were used to identify risk factors predicting complications.
Results:
850 patients underwent free flap reconstruction of head and neck defects during the study period (Male: 65.29%; Mean [SD] age: 54.90 [13.78] years). Postoperative complications developed in 125 (14.71%) patients, among which, 101 (11.88%) patients developed surgical complications, 29 (3.41%) patients developed medical complications and 5 (0.59%) patients developed both surgical and medical complications. Total flap necrosis was observed in 11 (1.29%) patients. After multivariate analysis, several risk factors incluing postoperative ICU admission, coronary heart disease, post radiotherapy surgery and flap types were identified correlated with postoperative complications.
Conclusions:
Our study identified related variables for a higher risk of postoperative complications development following free flap reconstruction of head and neck defects. Early detection of these risk factors will improve prognosis.
