ABSTRACT
<p><b>OBJECTIVE</b>To investigate the change of skeleton structure and masseter after mandibular angle osteotomy and its clinical significance in preoperative design.</p><p><b>METHODS</b>3-dimensional CT cephalometry was performed before and after surgery in 18 cases of prominent mandibular angle.</p><p><b>RESULTS</b>Pre- and post-operative data were compared. Significant differences between the pre- and post-operative data were found in the mandibular angle, the distance between mandibular angle, length of ramus, ectropion angle of mandibular angle, triangle Go-Me-Go, the thickness, width and length of masseter.</p><p><b>CONCLUSIONS</b>It indicates the skeleton structure is changed and some kind of atrophy happens in the masseter after operation. So we suggest partial resection of masseter should be unnecessary for mandibular angle osteotomy.</p>
