The Effect of Cold Saline Irrigation of Dissection Planes in Rhinoplasty on Postoperative Edema and Ecchymosis.

[BACKGROUND] Periorbital edema and ecchymosis are frequently encountered after rhinoplasty and may be distressing to patients. Cold therapy is frequently employed in rhinoplasty to reduce postoperative edema and ecchymosis.

[PURPOSE] The aim of this study was to evaluate the effect of cold saline irrigation (CSI) of dissection planes in rhinoplasty on postoperative edema and ecchymosis.

[STUDY DESIGN, SETTING, SAMPLE] The investigators designed a retrospective cohort study. The data of patients who underwent rhinoplasty in our clinic between January 2021 and January 2023 were scanned. Patients who underwent primary open rhinoplasty from the same surgeon and standard rhinoplasty steps were applied in the same way and order were included in the study. Patients who had systemic diseases and previous nose surgery, and patients whose photographs could not be accessed from the photograph archive were excluded.

[PREDICTOR VARIABLE] According to whether CSI was applied to the dissection plans during rhinoplasty, the patients were divided into the CSI group and the control group (without CSI).

[MAIN OUTCOME VARIABLES] Patients' grades of periorbital edema and ecchymosis were the main outcome variables. The differences of outcome variables were compared between the 2 groups.

[COVARIATES] Demographics (age, sex), and surgical detail (duration of surgery) were collected as covariates.

[ANALYSES] The numerical variables were compared between the two groups using the student's t-test and Mann-Whitney U test, whereas the categorical variables were compared using Pearson's χ and Fisher's exact tests. P < .05 was considered statistically significant.

[RESULTS] Among the 167 patients who met the inclusion criteria, 60 patients were randomly selected, 30 patients in each group. No statistically significant difference was found between the two groups in terms of age (P = .45) and sex (P = .27). The mean ecchymosis grade was statistically significant lower in the CSI group than in the control group for all evaluation times (P < .05). Similarly, the mean edema grade was statistically significant lower in the CSI group than in the control group for all evaluation times, with the exception of the 10th and 15th day (P < .05).

[CONCLUSION AND RELEVANCE] CSI of the dissection planes in rhinoplasty reduced the development of periorbital edema and ecchymosis. This procedure is straightforward, inexpensive, and effective.
