In addition, affected patients with a deformity of the condylar head have increased risk of these complications. We report a case of skeletal maxillary protrusion associated with hypoplasia of the bilateral mandibular condyles, in which a favorable outcome was attained by utilizing a combination of Le Fort I osteotomy and anterior segmental maxillary osteotomy procedures along with planned mandibular autorotation. A 26-year-old woman visited the Department of Orthodontic Dentistry at our hospital with complaints of maxillary protrusion and anterior open bite. The patient was diagnosed with hypoplasia of the bilateral mandibular condyles and maxillary protrusion associated with an open bite of the anterior teeth by several radiographic and orthodontic examinations, and was referred to our department for surgical correction. Preoperative orthodontic treatment was initially performed for 1 year 8 months, after which she underwent orthognathic surgery. The operation was two segmental Le Fort I osteotomy (a combination of Le Fort I and anterior segmental maxillary osteotomy), along with mandibular autorotation. At more than 2 years after surgery, the patient expressed satisfaction with changes in facial appearance and stable occlusion also remained. Accordingly, we consider that these surgical procedures may be effective for patients with maxillary protrusion associated with hypoplasia of the bilateral mandibular condyles.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123176549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Orthodontic tooth movement is much easier and more physiologically favorable after surgical elimination of the skeletal disharmony. For a successful SF orthognathic treatment, a proper collaboration between surgeons and orthodontists is believed to be essential. It is because surgical occlusion is constructed based on orthodontic simulation. Present presentation will present rationale of SF orthognathic treatment and suggest a clinical protocol for the success of ortho-surgical treatment.

Fourteen subjects (2 males and 12 females; average age 27.6 years) underwent orthognathic surgery at Oita Oka Hospital between November and the end of December 2017. The questionnaire had nine questions, including on the appearance of meals and so on. The patients were asked to fill in the questionnaire before being discharged. We recorded the dietary intake rate of meals provided for 3 days after surgery to calculate the amount of energy consumed and the nutrient adequacy based on the required amount of energy. This gave us an accurate picture of the dietary and nutritional intake situation. According to the questionnaire, 92% of patients said that the meals provided were easy or somewhat easy to eat. Regarding satisfaction with the diet, all patients answered that they were satisfied. However, regarding the appearance, 44% of the patients said that the meals provided were not very visually appealing, and 47% said the dietary amount was too much. The average amount of energy consumed for the 3 days after surgery was 705 kcal and the average nutrient adequacy was 35%. These results showed that the nutritional intake situation of patients who underwent orthognathic surgery was about three out of ten in terms of nutrient adequacy. Many patients felt the meals were easy to eat and were satisfied with the food currently offered by our department, but they felt that they had physical difficulties eating, and that the meal volume was large, which is considered to be a low nutrient adequacy.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131379038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
