Most patients with cleft lip and palate receive proper and consistent treatment; however, in some cases, patients are not satisfied with the treatment outcomes regardless of improvements in jaw function and morphology after orthognathic surgery, which is considered as one of the final phases of the treatment. 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.

Anxiety about complications after surgery is a critical factor that heavily influences the patientʼs decision on whether to have orthognathic surgery. 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”.

The most serious complications of standard Le Fort Ⅰ osteotomy occur as a consequence of pterygomaxillary separation. 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.
