Objective: To assess the postoperative stability and complications following orthognathic surgeries for patients with skeletal class III deformity with/without cleft lip and palate (CLP). Subjects and methods: The subjects were 34 patients with CLP who underwent orthognathic surgeries, including sagittal split ramus osteotomy in 11 patients, Le Fort I osteotomy in 9 patients, and two-jaw surgery in 14 patients. As a control, 7 patients treated with two-jaw surgery and 18 patients treated with SSRO without clefts were used. Retrospectively, the amount of jaw movement and intra- and postoperative complications were analyzed, and then compared among the five groups. Furthermore, the pre- and postoperative facial landmarks and relapse distances were measured based on lateral cephalograms. Results: There were no significant differences in the amount of jaw movement, operation time, or intraoperative bleeding. Cephalometric analysis demonstrated significantly greater maxillary hypo-growth in both the anteroposterior and the vertical directions in patients with CLP. No significant differences were observed in the relapse distance in the same operation between with and without CLP by ANOVA or velopharyngeal closure among the five groups by χ square test. Conclusions: Our orthognathic surgeries provided the same levels of stability and intraor postoperative complications for patients with skeletal class III with or without CLP
