THE EFFECT OF ST. JOHN'S WORT OİL APPLİCATİON ON PERIORBITAL EDEMA AND ECCHYMOSİS AFTER RHİNOPLASTY

Sponsor: Inonu University

Summary

Rhinoplasty is one of the most frequently performed procedures in aesthetic and reconstructive surgery, with steadily increasing demand worldwide. Periorbital ecchymosis and edema are common early postoperative complications, primarily resulting from soft tissue hemorrhage during osteotomy. Although these findings are considered part of the natural postoperative course, they may negatively affect patient comfort and satisfaction, particularly in young individuals with high aesthetic expectations. St. John's Wort (Hypericum perforatum) has been reported to possess anti-inflammatory, anti-edematous, and antispasmodic properties. This study aims to evaluate the effect of topical St. John's Wort oil on postoperative periorbital edema and ecchymosis in patients undergoing rhinoplasty. Methods This randomized controlled experimental study will be conducted in a university hospital setting. The study population will consist of patients scheduled for rhinoplasty, and the sample will include those who provide informed consent. Participants will be randomly assigned to either the experimental group (n = 55) or the control group (n = 55). In addition to routine postoperative care, the experimental group will receive topical St. John's Wort oil application, while the control group will receive routine care alone. Data will be collected using a Personal Information Form, the Upper and Lower Eyelid Ecchymosis Assessment Scale, and the Eyelid Edema Assessment Scale. Assessments will be performed on postoperative Day 0, Day 1 (24 hours), Day 3 (72 hours), and Day 7 (168 hours). Statistical analyses will be conducted using SPSS version 25. Data distribution will be assessed for normality, and appropriate parametric or non-parametric tests will be applied. Statistical significance will be set at p \< 0.05. Results It is anticipated that patients receiving topical St. John's Wort oil will demonstrate significantly lower periorbital edema and ecchymosis scores compared to the control group during the early postoperative period. Conclusion Given the role of soft tissue hemorrhage in the development of postoperative ecchymosis and edema, and considering the documented pharmacological properties of St. John's Wort, topical application may represent a safe and effective adjunctive intervention for reducing periorbital complications following rhinoplasty. Further clinical evidence may support its integration into routine postoperative care protocols. Aim of the Study The aim of this study is to investigate the effect of St. John's Wort oil (Hypericum perforatum) on postoperative periorbital edema and ecchymosis in patients undergoing rhinoplasty. Hypotheses H0a (Null Hypothesis): St. John's Wort oil (Hypericum perforatum) has no effect on postoperative periorbital edema following rhinoplasty. H1a (Alternative Hypothesis): St. John's Wort oil (Hypericum perforatum) has a significant effect on postoperative periorbital edema following rhinoplasty. H0b (Null Hypothesis): St. John's Wort oil (Hypericum perforatum) has no effect on postoperative periorbital ecchymosis following rhinoplasty. H1b (Alternative Hypothesis): St. John's Wort oil (Hypericum perforatum) has a significant effect on postoperative periorbital ecchymosis following rhinoplasty.
