Therefore, to improve patients’ satisfaction with the treatment, their psychological conditions were surveyed before and after orthognathic surgery. Thirty-four patients with cleft lip and palate completed a psychological test （MINI-124） before orthognathic surgery, and the findings revealed that the majority showed high scores in each scale designed for measuring lie, hysteria, and association problem. Furthermore, the scores of hypochondriasis, hysteria, and bodily symptoms were significantly higher in patients with cleft lip and palate than in 70 jaw deformity patients without any congenital anomalies measured before surgery. In addition, a questionnaire survey on the orthognathic surgery performed at more than 6 months after the surgery, showed that patients with cleft lip and palate were mostly satisfied with their surgeries. However, some of them showed a slightly lower degree of satisfaction and a strong obsession with their lip scars and nasal deformities.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"10 5 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":"130441129","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}

The patient was a female aged 18 years and 5 months at the first visit with the chief complaint of mandibular protrusion and space between maxillary anterior teeth. She had a concave facial profile with slight midfacial concavity. ∠ANB was −6.0°, ∠SNA was 78.5° and ∠SNB was 84.5°. The intraoral view showed anterior and posterior crossbite. The molar relationship was Angle ClassIII. Lower incisors showed lingual inclination because of dental compensation. In the conventional treatment, labial tipping of the lower incisors was likely to generate interdental spaces in the mandibular arch with mild crowding. Subsequently, in the process of closing spaces, retroclination of the incisors was frequently seen. In the present case, we used orthodontic anchor screws to maintain the lower incisor angle during presurgical orthodontic treatment. After 14 months of preoperative orthodontic treatment, Le Fort I osteotomy and intraoral vertical osteotomy (IVRO)were performed. As a result, the mandibular incisors were inclined labially by 7.0°. The posterior part of the maxilla was moved superiorly by 4.5mm and the mandible was set back by 11.5mm at the menton. The crossbite and concave facial profile were improved by the appropriate amount of mandibular set-back. Additionally, condylar movement and incisal paths(opening and closing, lateral excursive movements)were also improved at 25 months after the initiation of retention.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"27 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":"116949606","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}

Herein, we encountered a case of bone resorption and fistula that occurred in a patient who had undergone silicone implantation at another hospital. We removed the implant and performed fistula closure using the rhomboid-to-W technique. A 39-year-old woman visited our hospital because a fistula with pus discharge had developed in the lower portion of the mental region. Computed tomography and magnetic resonance imaging showed the presence of a silicone implant, as well as compression of the bone in the midline of the anterior region of the mandible. The fistula was contiguous with the silicone implant. Based on the medical history and image-based findings, the patient was diagnosed with an infection caused by the silicone implant. For removal of the implant and fistula closure, the rhomboid-to-W technique was applied because of the availability of a secured surgical field and consideration for postoperative esthetics. Two years after surgery, the progress remains favorable.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"131 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":"132186628","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}

Also, we need to grasp the patientʼs pain and anxiety in postoperative management. In nursing research, abstract anxiety is embodied in various ways to help postoperative management. The purpose of this study was to analyze the psychological state using text mining based on a diary written by a patient who had undergone orthognathic surgery. A 24-year-old man was referred to our hospital for orthodontic surgery from a local orthodontic office. We performed sagittal splitting ramus osteotomy followed by nine days of hospitalization including postoperative management. The patient was asked to keep a diary and freely describe changes in mental state and life from the time of entering the operating room to 17 days after the operation. In order to perform qualitative data analysis of the descriptive contents, the text mining software KH-Coder was used to perform morphological analysis, and then the extracted words were classified by cluster analysis and co-occurrence network, respectively. In addition, correspondence analysis was conducted during hospitalization and after discharge, and each characteristic word was read. In the language extracted by morphological analysis, the characteristic words of the diary were “swelling”, “mouth”, “opening”, “big”, and “cheek”. In the cluster analysis, the extracted language was classified into 10 clusters, and in the co-occurrence network, the extracted language was classified into 12 groups. When the classified clusters and groups were interpreted, “opening”, “swelling”, “sleep”, “nasogastric tube”, “pain”, and “surgery” were common. The characteristic words of correspondence analysis were over” and “dinner” in hospitalization and “correcting physician”, “posture”, etc. after discharge from the hospital. Immediately after surgery, consciousness about “nasogastric tube”, “cheek swelling”, “diet”, “pain”, “sleep”, and “opening/closing of mouth” was strong; after discharge, consciousness about “cheek swelling”, “pain” and “opening/closing of mouth” was strong. We found that consciousness of “opening”, “swelling”, “sleep”, “nasogastric tube”, “pain” and “surgery” is strong in the analysis of text mining after orthognathic surgery. Both during hospitalization and after discharge, the patient continued to be conscious of “opening”, “swelling” and “pain”.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"96 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":"122971151","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}

To reduce the risk of unexpected fracture during pterygomaxillary separation, Trimble et al. reported a modification of pterygoid plate separation while performing low-level maxillary osteotomy. On the other hand, recently, there have been some reports that piezoelectric osteotomy could reduce blood loss and inferior alveolar nerve injury during orthognathic surgery. To reduce the complications following pterygomaxillary separation, we have performed Le Fort Ⅰ osteotomy with tuberosity separation using an ultrasonic bone cutting instrument and customized curved osteotome. Thirty-six patients （15 males and 21 females） underwent Le Fort Ⅰ osteotomy with tuberosity separation at the Department of Oral Surgery, Kanagawa Dental University, Yokohama Clinic from October 2017 to March 2019. The mean operation time and blood loss were 213.4±45.3 （mean±SD）min and 155.8±87.2 （mean±SD）ml, respectively. Computed tomography images taken one year after surgery showed a continuous radiopaque area between the pterygoid plate and maxillary tuberosity. The postoperative stability of the maxilla was excellent in all cases. These results show that tuberosity separation in Le Fort Ⅰ osteotomy using an ultrasonic bone cutting instrument and customized curved osteotome is an efficacious and safe surgical technique.","PeriodicalId":102257,"journal":{"name":"The Japanese Journal of Jaw Deformities","volume":"17 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":"128154856","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}
