The patient was a female with mandibular prognathism due to maxillary retroposition and mandibular protrusion, and presented with transverse maxillary deficiency, skeletal asymmetry, and limitation of condylar movement. Rapid Palatal Expansion and further expansion by segmental high LeFort I osteotomy was performed to harmonize the maxillomandibular arch width. Segmental high LeFort I osteotomy also resulted in improvement of the midfacial profile. Furthermore, after IVRO, facial symmetry and a good facial profile were achieved, and the condylar movement increased. The occlusion, esthetics and stomatognathic function were stable after 2 years of retention.
