ObjectiveThis study was aimed at investigating the correlation between intraoperative blood loss and operation-related factors in the treatment of bimaxillary protrusion with four different procedures.Study DesignNinety-four patients were separated into the following four surgical groups: group 1: anterior subapical osteotomy of the maxilla (ASO Mx) + bilateral parasymphyseal osteotomy of the mandible (BPsO Md) + genioplasty (GeP); group 2: ASO Mx + BPsO Md; group 3: ASO Mx + ASO Md + GeP; and group 4: ASO Mx + ASO Md. Patient- and operation-related factors (age, intraoperative blood loss, operation time, and preoperative and postoperative blood parameters) were compared among the four groups.ResultsThe mean operation time and intraoperative blood loss were 438.7 minutes and 369.9 mL in group 1; 432.5 minutes and 356.5 mL in group 2; 393.3 minutes and 387.3 mL in group 3; and 353.5 minutes and 289.5 mL in group 4. Intergroup differences in intraoperative blood loss were not significant. A significant correlation between intraoperative blood loss and operation time was found in group 4 but not in the other groups.ConclusionsNo significant differences in blood loss were found among the four different surgical procedures in the treatment of bimaxillary protrusion.
