This study aims to quantitatively evaluate the bone quality of orthognathic surgery patients with and without cleft lip and palate. Bone thickness and bone density were measured from standard anatomical points on computed tomography images and compared among cleft orthognathic patients (Group I), non-cleft orthognathic patients (Group II), and a healthy control group (Group III). Each group consisted of 24 patients, and there were no statistically significant differences among the groups regarding gender distribution or age. Group I exhibited significantly lower bone density and thickness in both the medial and lateral buttresses compared to Groups II and III. However, no significant differences in bone density or thickness were observed between Groups II and III. Within Group I, the lateral buttress density and thickness were significantly higher than those of the medial buttress. Additionally, both medial and lateral buttress density and thickness on the cleft side were significantly lower than on the non-cleft side. In cleft patients, the bone quality of both buttresses is decreased, with the cleft side and medial buttress being more affected than the non-cleft side and lateral buttress. Therefore, special attention should be given during the fixation of the medial buttress and cleft side.
