<h2><strong>Background: </strong>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.</h2><p><strong>M</strong><strong>aterials and Methods: </strong>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.</p><p><strong>R</strong><strong>es</strong><strong>ults: </strong>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.</p><p><strong>C</strong><strong>onclusion: </strong>local injection of Lidocaine/Adrenaline solution immediately before lateral osteotomy could not reduce postoperative edema and ecchymosis in rhinoplasty.</p>
