A female patient (aged 26\u00a0years, 2\u00a0months) presented with a chief complaint of dysmasesis caused by scissor bite on the right side. The clinical examination revealed difficulty in lip closure and a convex profile. Overerupted right maxillary premolars and molars and lingual tipping of the right mandibular premolars and molars were indicated before treatment. After 3\u00a0months of presurgical orthodontic treatment, two-jaw surgery involving a combination of HLFO with mid-alveolar osteotomy and BSSRO was performed. A good interdigitation in the right side was established by superior-posterior-medial movement of the dento-alveolar segment of the maxilla. Next, both the maxilla and mandible were moved superiorly and posteriorly to correct the improper lip protrusion, thereby improving the patient's profile. Our results suggest that this new orthognathic surgery technique\u2014achieved by combining HLFO with mid-alveolar osteotomy and BSSRO\u2014is effective for adult patients exhibiting severe unilateral scissor bite and bimaxillary protrusion.<\/jats:p>","DOI":"10.2319\/050513-344.1","type":"journal-article","created":{"date-parts":[[2013,9,25]],"date-time":"2013-09-25T12:17:56Z","timestamp":1380111476000},"page":"374-379","source":"Crossref","is-referenced-by-count":15,"title":["Severe unilateral scissor bite and bimaxillary protrusion treated by horseshoe Le Fort I osteotomy combined with mid-alveolar osteotomy"],"prefix":"10.2319","volume":"84","author":[{"given":"Kazuo","family":"Shimazaki","sequence":"first","affiliation":[{"name":"Assistant Professor, Orthodontic Science, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunihiko","family":"Otsubo","sequence":"additional","affiliation":[{"name":"Director and Head Orthodontist, Otsubo Orthodontic Clinic, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ikuo","family":"Yonemitsu","sequence":"additional","affiliation":[{"name":"Assistant Professor, Orthodontic Science, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sachiko","family":"Kimizuka","sequence":"additional","affiliation":[{"name":"Clinical Fellow, Department of Oral and Maxillofacial Surgery, Yokohama City University Medical Center, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susumu","family":"Omura","sequence":"additional","affiliation":[{"name":"Associate Professor, Department of Oral and Maxillofacial Surgery, Yokohama City University Medical Center, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Ono","sequence":"additional","affiliation":[{"name":"Professor and Chair, Orthodontic Science, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1164","reference":[{"key":"i0003-3219-84-2-374-b01","series-title":"Am J Orthod Dentofacial Orthop","first-page":"728","article-title":"Treatment of a Class II division 1 malocclusion with a severe unilateral lingual crossbite with combined orthodontic\/orthognathic surgery","volume":"117","author":"Cureton\n              SL,","year":"2000","unstructured":"Cureton\n              SL, \n            \n              Bice\n              R, \n            \n              Strider\n              J. \n          \n          Treatment of a Class II division 1 malocclusion with a severe unilateral lingual crossbite with combined orthodontic\/orthognathic surgery.
