Introduction: Controlled hypotension during surgical procedure is a way to decrease blood pressure and subsequently, improve field of operation. Clonidine is an antihypertensive agent used for induced hypotension. Correction of maxillomandibular discrepancies may need to perform osteotomy on both jaws in many cases which is associated with significant blood loss. Material and Methods: 30 participants candidate to double-jaw orthognathic surgery were classified into two groups with equal number. In one group, 300microgram oral clonidine premedication, 90 minutes before operation and in the other group a placebo with the same condition as group 1 were administered. Mean arterial pressure (MAP) and heart rate in 10 minutes interval, operation time, blood loss and surgeon's satisfaction were measured. Results: 10 men and 5 women with the mean age of 22.9 ± 2.9 in study group and 13 men and 2 women with the mean age of 22.1± 2.1 in control group were evaluated. The MAP was significantly lower in clonidine group (P value <0.001). Intra-operative bleeding was 508.67± 46.2 milliliter (mL) in placebo group and 287.33±72.06mL in clonidine group and the difference was statistically significant (P <0.05). Significant differences were observed in operation time (P <0.05) and surgeon's satisfaction (P<0.001). Conclusion: The authors of this study suggest clonidine premedication in bimaxillary orthognathic surgery. Hemodynamic stability, bleeding control, decreasing the operation time and enhancing the surgical results are advantages of this method.
