We made a retrospective study on the usefulness of autologous blood transfusion conducted by using stored autologous blood with or without blood dilution in orthognathic surgery. Ninety-six patients had received autotransfusion in our department from 1985 through 1991.<BR>Their mean age was 19.8 years.Females predominated over males in the ratio of about three to one.The main disorder of the patients was prognathism (90cases);the major method of operation was a sagittal splitting ramus osteotomy.The average volume of autologous blood donation was 525.1ml, and 72% of blood loss was covered by autologous blood transfusion.Hematologically postoperative anemia of the patients was recovered with autotransfusion, and serum erythropoietin levels in autologous donors increased significantly (P<0.05).No complications were observed and clinical courses of all cases were satisfactory.<BR>The above results indicate that autologous blood transfusion is quite safe and can be recommended for use in orthognathic surgery.
