Maxillary-malar deficiency is the most frequently occurring midface dentofacial deformity. Clinicaly patients with maxillary-malar deficiency exhibit malar and infraorbital rim deficiency and class III malocclusion. For treatment of these deformities, modified LeFort III osteotomy have been used. Modified LeFort III osteotomy advances maxilla with orbital rims and zygomatic bone anteroposteriorly. This is a case of patient who had severe mandibular prognthism with midface deformity. We performed modified LeFort III osteotomy for maxillary-malar advancement and simultaneous bilateral sagittal split ramus osteotomy for mandibular prognathism and autogenous iliac bone graft.
