Abstract

True midfacial deficiency is defined as a hypoplasia of various components of midface such as maxilla, orbit, zygoma and nasal bone. For treatment of these anomalies Le Fort III osteotomy and its modifications have been used traditionally. Le Fort III osteotomy is the method which advances maxilla with nasal bone and zygomatic bone at a time. At first midfacial osteotomy was introduced by Gillies to treatment of dentofacial deformity in 1950. In 1967 Tessier designed Le Fort III osteotomy according to Le Fort III midfacial fracture line and popularized to treat midfacial deficiency using coronal incision to appoach osteotomy sites. This is a case of patient who had mandibular prognathism with midfacial deficiency with severe discrepancy in maxillomandibular interrelation. First we performed Le Fort III osteomomy for zygomaticomaxillary advancement, and then carried out simultaneous two jaw surgery with Le Fort I osteotomy and BSSRO three months after first surgery.
