Purpose: This study investigated the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR) and severe postoperative edema and ecchymosis after open rhinoplasty. Materials and Methods: The study was carried out retrospectively in 165 ASA I-II patients aged 18-45 years who underwent open rhinoplasty in the Department of Plastic and Reconstructive Surgery. The patients were grouped based on their scores on the edema and ecchymosis scales. The degree of edema and ecchymosis was considered “minimal” (Group M) in those scoring 0-2 points and “severe” (Group S) in those scoring 3-4 points. Periorbital edema and ecchymosis of the patients in both groups were scored based on the digital photographs taken on the 1st postoperative day. Results: There was no significant difference in the demographic and clinical characteristics of the patients grouped according to the degree of edema and ecchymosis. The optimal cut-off value of NLR was 2.1 (AUC = 0.747, Sensitivity = 0.666, Specificity = 0.707) for edema and 1.5 (AUC = 0.747, Sensitivity = 0.869, Specificity = 0.470) for ecchymosis. Multivariable analyzes for the development of edema and ecchymosis identified NLR (4.67 [2.38-9.40] and 6.54 [3.02-15.08, respectively) as a statistically significant independent prognostic factor. Conclusion: This study identified preoperative NLR as a predictor value of severe postoperative edema and ecchymosis after open rhinoplasty.
