Moderns have desire likely to be further good-looking concomitant with a qulitative advancement of the life. Orthognathic surgery for the correction of dentofacial deformities is a common elective procedure. It's possible to occur many complication during the operations and especially, an excesseive bleeding of those may be fatal and so a tranfusion is performing for the prevention and management of that. The most notable of these for reduction of blood loss is the utilization of induced hypotensive anesthetic technique to reduce the mean arterial pressure between 55 and 60 mmHb. Another method for dealing with blood loss following orthognathic surgery is the transfusion of blood obtained as an autologous tranfusion or from banked blood. Some of the disadvantage of banked blood are overcome with the use of predeposited autologous transfusion. But currently, surgeons try so that even autologous transfusion may not transfuse the patients. We made a comparative study of hematologic change and transfusion requirement based on a series of 200 patients who had an orthognathic surgical procedure at Chonbuk National University during the period 2001-2005. This study is to make a comparative analysis of an post-operative hematologic (Hemoglobin, Hematocrit, Red blood cell) change and duration of the procedure under induced hypotensive anesthesia in healthy orthognathic patients.
