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.
