Objective The aims of this study were (1) to evaluate postoperative stability and (2) to examine bone healing in the pterygomaxillary region after total maxillary setback surgery to correct dentofacial deformities. Study Design A total of 27 patients with maxillary protrusion who underwent a 1-piece LeFort I osteotomy and bilateral sagittal split ramus osteotomy were evaluated. The amounts of postoperative relapse were analyzed and compared using cephalometric analysis, and the bone healing in the pterygomaxillary region was evaluated by computed tomography. Results At >6 months after surgery, there was no statistically significant horizontal or vertical relapse. The tendency to relapse did not significantly increase with an extensive amount of maxillary setback. Significant osseous regeneration at the pterygomaxillary region occurred in the early phase of recovery (P < .001). Conclusions This study suggests that total maxillary setback provides a successful outcome with good stability for the correction of maxillary protrusion.
