Does Injection of Lidocaine with 1/100000 Epinephrine Immediately before Lateral Osteotomy Reduce Post-Operative Periorbital Edema and Ecchymosis in Rhinoplasty?

摘要

Background: Postoperative periorbital edema and ecchymosis are common after rhinoplasty. We studied the effect of local injection of Lidocaine/Adrenaline immediately before osteotomy on prevention of post-operative periorbital edema and ecchymosis in rhinoplasty. M aterials and Methods: Thirty healthy candidates for rhinoplasty were enrolled in the self-controlled clinical trial study. Lidocaine/Adrenaline solution injected randomly to one side just prior to the lateral osteotomy. The opposite side used as a control. The degree of edema/ecchymosis on both sides was compared on the 1st, 2nd and 7th day postoperatively. R es ults: Mean of severity of edema, 24 hours after operation was 3in both sides, (Mann-whitney U; p=0.829). Mean of severity of edema, 48 hours after operation was 2 in both sides (Mann-whitney U; p=0.867) and it was 1 in both sides 7 days after operation (Mann-whitney U; p=0.756).There was no significant difference between two sides. Mean of severity of ecchymosis, 24 hours after operation was 3 in both sides (Mann-whitney U; p=0.692). Mean of severity of ecchymosis, 48 hours after operation was 2 in both sides (Mann-whitney U; p=0.655) and it was 1 in both sides 7 days after operation (Mann-whitney U; p=0.873). There was no significant difference between two sides. C onclusion: local injection of Lidocaine/Adrenaline solution immediately before lateral osteotomy could not reduce postoperative edema and ecchymosis in rhinoplasty.
