Introduction: One of the most important problems during cosmetic nose surgery is excessive bleeding. Controlled hypotension is an appropriate technique for reducing intraoperative bleeding as well as satisfactory and non-bloody surgical field. Different drugs, such as dexmedetomidine and remifentanil, are used to control hypotension. The aim of this study was to compare the effect of dexmedetomidine and remifentanil on the creation of control hypotension during rhinoplasty. Material and Method: This study is a randomized, double-blind clinical trial which was performed on 60 patients randomly divided into two groups D (Dexmedetomidine) and R (Remifentanil). In group D (0.5 mg / kg / h) Dexmedetomidine infusion and in group R (50-100 µg / kg / h) Remifentanil infusion. The study groups were compared in terms of hemodynamics and intraoperative bleeding. The data obtained from completed questionnaires were analyzed using SPSS software, T-test and ANOVA statistical tests and were presented in tables and statistical charts. Results: The results of this study showed that the mean MAP (Mean Arterial Pressure) was significantly lower in remifentanil group patients than in dexmedetomidine group, while the intraoperative bradycardia rate was different at various time. Conclusion: During rhinoplasty surgery, both dexmedetomidine and remifentanil were effective in controlling hypotension and reducing intraoperative bleeding, but the effect of remifentanil was more pronounced than dexmedetomidin
