Nowadays bilateral sagittal split osteotomy (BSSO) is the most common technique for treatment of mandibular skeletal deformities. One of the most sensitive stages in BSSO is recognition of inferior alveolar nerve entrance. This technical note presents a noble and safe approach for medial osteotomy in BSSO which is based on anatomy of mandible during the surgery. In this approach osteotomy initi...

OBJECTIVE To compare postoperative maxillary stability following Le Fort I osteotomy for the correction of occlusal cant as compared with conventional Le Fort I osteotomy for maxillary advancement. STUDY DESIGN The subjects were 40 Japanese adults with jaw deformities. Of these, 20 underwent a Le Fort I osteotomy and intraoral vertical ramus osteotomy (IVRO) to correct asymmetric skeletal mor...

OBJECTIVES To evaluate the influence of the type of osteotomy in the inferior aspect of the mandible on the mechanical performance. MATERIALS AND METHODS The study was performed on 20 polyurethane hemimandibles. A sagittal split ramus osteotomy (SSRO) was designed in 10 hemimandibles (group 1) with a vertical osteotomy in the buccal side (second molar level) and final osteotomy was performed ...

PURPOSE To evaluate pharyngeal airway volume changes after forward movements of the maxilla or mandible, or both, using cone-beam computed tomography. PATIENTS AND METHODS A retrospective evaluation of 30 patients who underwent maxillomandibular advancement, maxillary advancement, or mandibular advancement was performed. Three groups of 10 subjects each were established: group 1, bimaxillary ...
