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.
大多数唇腭裂患者得到了适当和一致的治疗;然而,在某些情况下,尽管正颌手术后颌骨功能和形态有所改善,但患者对治疗结果并不满意,这被认为是治疗的最后阶段之一。因此,为了提高患者对治疗的满意度,我们对正颌手术前后患者的心理状况进行了调查。34例唇腭裂患者在正颌手术前完成了一项心理测试(MINI-124),结果显示,大多数唇腭裂患者在谎言、歇斯底里和关联问题的每一项量表上都取得了高分。此外,唇腭裂患者的疑病症、歇斯底里和躯体症状得分明显高于术前测量的70例无先天性异常的颌骨畸形患者。此外,对术后6个月以上进行的正颌手术的问卷调查显示,唇腭裂患者对手术的满意度较高。然而,他们中的一些人表现出稍低的满意度,对他们的嘴唇疤痕和鼻畸形有强烈的困扰。

We report a case of skeletal mandibular protrusion with dwarfed teeth treated by dental decompensation using anchor screws. 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.
我们报告一例骨性下颌骨突出伴矮小牙用锚钉治疗牙失代偿。患者为女性,年龄18岁零5个月,首次就诊时主诉为下颌前牙突出和上颌前牙间隙。她的面部轮廓呈凹状,面部中部略凹。∠ANB为−6.0°,∠SNA为78.5°,∠SNB为84.5°。口内观显示前后交叉咬合。摩尔关系为角级。由于牙齿代偿,下门牙呈现舌侧倾斜。在常规治疗中,下门牙的唇倾可能在下颌弓产生牙间间隙,并伴有轻度拥挤。随后,在闭合间隙的过程中,经常出现门牙的后倾。在本病例中,我们在术前正畸治疗中使用正畸锚钉来维持下切牙角度。术前正畸治疗14个月后,行Le Fort I型截骨术和口内垂直截骨术(IVRO)。结果:下颚切牙唇侧倾斜7.0°。上颌后部上移4.5mm,下颌骨下端后移11.5mm。适当的下颌骨后缩可改善牙合和面部凹形。此外,髁突运动和切径(打开和关闭,外侧漂移运动)在开始固位后25个月也得到改善。

Chin augmentation using silicone implants is often performed in the field of cosmetic surgery, and has been associated with greater bone resorption and postsurgi-cal infections. 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.

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”.
术后对并发症的焦虑是影响患者决定是否进行正颌手术的关键因素。同时,在术后处理中要把握患者的疼痛和焦虑。在护理研究中,抽象焦虑以各种方式体现出来,以帮助术后管理。本研究的目的是分析心理状态的文本挖掘基于日记的病人谁接受了正颌手术。一名24岁男子从当地正畸诊所转介到我院进行正畸手术。我们进行矢状劈裂支截骨术,随后住院9天,包括术后处理。要求患者记日记,自由描述从进入手术室到术后17天的精神状态和生活变化。为了对描述性内容进行定性数据分析,使用文本挖掘软件KH-Coder进行形态学分析,然后分别使用聚类分析和共现网络对提取的词进行分类。并在住院期间和出院后进行对应分析,读取每个特征词。在形态分析提取的语言中,日记的特征词为“肿”、“口”、“开”、“大”、“颊”。在聚类分析中,将提取的语言分为10个聚类,在共现网络中,将提取的语言分为12个组。当分类簇和组被解释时,“开放”、“肿胀”、“睡眠”、“鼻胃管”、“疼痛”和“手术”是常见的。对应分析的特征性词汇为住院时的“过”、“吃饭”,出院后的“矫正医师”、“姿势”等。术后即刻“鼻胃管”、“颊肿”、“饮食”、“疼痛”、“睡眠”、“开/闭口”意识较强;出院后“脸颊肿”、“疼痛”、“开口/闭口”意识较强。我们发现,在正颌手术后的文本挖掘分析中,“开放”、“肿胀”、“睡眠”、“鼻胃管”、“疼痛”和“手术”的意识较强。住院期间及出院后,患者持续有“开口”、“肿胀”、“疼痛”的意识。

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.
标准Le Fort截骨术Ⅰ最严重的并发症是翼颌分离的结果。为了降低翼颌分离过程中意外骨折的风险,Trimble等人报道了在低位上颌截骨时翼状钢板分离的改进。另一方面,近年来也有报道称压电截骨术可以减少正颌手术时的失血量和下牙槽神经损伤。为了减少翼颌分离术后的并发症,我们采用超声截骨仪和定制的弧形截骨术进行Le FortⅠ截骨术并结节分离。2017年10月至2019年3月,36例患者(男性15例,女性21例)在神奈川牙科大学横滨诊所口腔外科行Le FortⅠ截骨术并结节分离。平均手术时间213.4±45.3 (mean±SD)min,出血量155.8±87.2 (mean±SD)ml。术后一年的计算机断层图像显示翼状骨板和上颌结节之间有连续的不透射线区域。所有病例术后上颌骨稳定性良好。结果表明,采用超声截骨仪和定制曲线截骨术进行Le FortⅠ截骨术中结节分离是一种有效、安全的手术技术。
