Background : The coronal incision is versatile surgical approach to upper and middle region of the facial skeletal including the zygomatic arch. The advantages of coronal approach are minimal injury of facial tissue including facial nerve and satisfactory cosmetic result by hidden scar at hair. But wide exposure of scalp, its disadvantages are operation time and massive blood loss. Methods : Thirty patients undergoing elective surgery were divided 3 groups. Group I used only coronal approach, group II used coronal with subciliary approach and group III used coronal with subciliary and intraoral approach. And then retrospected of the preoperative, postoperative red blood cell count, hemoglobin(Hb), hematocrit, transfused red blood cell units and platelet cell units, and the amount of infused crystalloids and colloids, and postoperative hemovac count was estimated. Results: 1. Red blood cell count were decreased in all groups at immediated postoperation and decreased in all group of postoperative first day and decreased in group I, II but increased group III of postoperative third day. 2. Hemoglobin and hematocrit were decreased in all group at immediated postoperation and decreased in all group of postoperative first day and decreased in group I, II., but increased group III postoperative third day. 3. Platelet was decreased in all group at immediated postoperation, and decreased in group II, III but increased in group I of postoperative first day and decreased in group I but increased group II, III of postoperative third day. 4. Mean postoperative hemovac mean drainage group I of first day is $48.63{pm}21.12ml$ and second day is $23.92{pm}19.53ml$ and third day is $7.82{pm}5.32ml$ and group II of first day $60.45{pm}22.65ml$ and second day is $22.14{pm}13.21ml$ and third day is $7.32{pm}6.25ml$. III group of first day $58.16{pm}10.13ml$ and second day is $21.27{pm}11.72ml$ and third day is $7.13{pm}4.90ml$. 5. Infusion of group I is mean PRC $1.08{pm}0.91$ pint, FFP $1.03{pm}0.75$ pint, crystalloid $2562.23{pm}1345.53ml$ and group II is mean PRC $1.05{pm}0.89$ pint, FFP $1.71{pm}0.78$, crystalloid $2650.47{pm}1096.36ml$ and group III is mean PRC $1.79{pm}1.45$ pint, crystalloid $3295.43{pm}1472.432ml$.
