华西口腔医院正颌外科专科医师规范化培训改革探索

专科医师培训是我国临床医师培训的一个重要内容。正颌外科是口腔颌面外科的亚专业之一,也是口腔颌面外科专科医师培训中不可或缺的一部分。目前我国的正颌外科专科医师的数量匮乏,在正颌外科专科医师培训方面存在各种困难和不足。本文通过分析目前国内正颌外科专科医师培训的现状和困难,介绍我们在建立正颌外科专科医师规范化培训体系方面的尝试与经验,并为最终培养出规范、标准、具有完整专科知识体系的正颌外科专科人才提供有价值的参考。     

牙颌面畸形外科治疗的术前术后正畸

牙颌面畸形外科治疗的术前术后正畸傅民魁张丁当代正颌外科学发展的一个重要特点是，在进行外科手术矫治的同时，需要术前、术后正畸治疗的配合，以达到高水平的临床治疗效果。因此，正颌外科有别于单纯的整形颌骨，而且，牙颌面畸形的正颌外科治疗，应由口腔颌面外科医师...     

正颌外科围手术期准备

正颌外科是近几十年来口腔颌面外科和口腔正畸学共同发展所取得的最新成果之一,即通过口腔颌面外科与口腔正畸学的密切结合,共同矫治牙、颌、面畸形,同时解决咬合的问题。它包括牙齿的矫正,也包括颌骨的矫治,使牙、口、颌面功能和形态达到完满、协调和统一。与一般意义上的治病救人概念有所不同,正颌外科一方面使患者的牙、颌功能得到矫治,而另一方面是改善患者的容貌,使患者更加容貌美。所以,面对需要正颌外科矫治的患者,医生必须从以下几方面着手考虑问题。此也是正颌外科围手术期准备的最基本程序。1　常见的牙颌面畸形根据颌骨畸形的受…

随着口腔正畸学的发展与成熟,口腔正畸医生和颌面外科医生通过良好的合作,有效地将口腔正畸学与颌面外科学紧密地结合起来,形成口腔正畸-正颌外科联合治疗骨性错耠畸形的治疗手段。正颌外科对于颌面部和牙弓形态学的改善已经得到学术界的普遍认可,并且获得越来越多患者的接受。正颌手术治疗后,患者颌骨和牙齿均有移动,打破了原有的口颌系统,重建咬合平衡。近些年来,关于患者正颌手术治疗后口颌系统功能改变的研究一直受到广泛关注并存在很多争议。本文就近年来正颌手术治疗后口腔生理功能变化的相关研究进展做一综述。

Assessing the economic return of specializing in orthodontics or oral and maxillofacial surgery.

BACKGROUND: The authors determined the economic returns from an educational investment in the specialties of orthodontics and oral an maxillofacial surgery. They also addressed problems found in previous studies. METHODS: The marginal return for specializing in orthodontics or oral and maxillofacial surgery was determined using net present value and internal rate of return, or IRR, with the income of the general dentist serving as the common opportunity cost. Extreme scenario, threshold and one-way sensitivity analyses were used to account for variation in the data. RESULTS: The median group of orthodontists broke even 5.9 years after specialty training and had a working lifetime net return of $271,536 above that of general dentists; the IRR for them was 10.36 percent. The median group of oral and maxillofacial surgeons broke even 2.3 years after training and had a working lifetime net return of $587,563 above that of general dentists; the IRR for them was 25.30 percent. CONCLUSIONS: Under the most likely conditions, the authors found a positive economic return to dentists in both specialties from their additional dental training. PRACTICE IMPLICATIONS: The positive financial returns brought by specialization indicate that the demand for additional dental education should continue within an environment of increased educational investment costs.     

Characteristics of an oral and maxillofacial radiology department: Report of the ad hoc Department Characteristics Committee of the American Academy of Oral and Maxillofacial Radiology

Oral and maxillofacial radiology is a dynamic and multifaceted discipline that plays a critical role in patient care, the education of general dentists and dental specialists, and the academic health of the dental school. Diagnostic and treatment advances in temporomandibular joint disorders (TMD), implants, trauma and orthognathic surgery, and craniofacial abnormalities depend heavily on conventional and advanced imaging techniques. Oral and maxillofacial radiology contributes to the education of pre- and post-doctoral dental students with respect to biomedical and clinical knowledge, cognitive and psychomotor skills, and the professional and ethical values necessary to properly prescribe, obtain, and interpret radiographs. The development of an active and successful oral and maxillofacial radiology department, division, or section requires the committment of institutional resources. This document may serve as a guide to dental schools committed to excellence in oral and maxillofacial radiology.     

Risk of surgical glove perforation in oral and maxillofacial surgery

Oral and maxillofacial surgery, which involves several sharp instruments and fixation materials, is consistently at a high risk for cross-contamination due to perforated gloves, but it is unclear how often such perforations occur. This study aimed to address this issue. The frequency of the perforation of surgical gloves (n=1436) in 150 oral and maxillofacial surgeries including orthognathic surgery (n=45) was assessed by the hydroinsufflation technique. Orthognathic surgery had the highest perforation rate in at least 1 glove in 1 operation (91.1%), followed by cleft lip and palate surgery (55.0%), excision of oral soft tumour (54.5%) and dental implantation (50.0%). The perforation rate in scrub nurses was 63.4%, followed by 44.4% in surgeons and first assistants, and 16.3% in second assistants. The odds ratio for the perforation rate in orthognathic surgery versus other surgeries was 16.0 (95% confidence interval: 5.3-48.0). The protection rate offered by double gloving in orthognathic surgery was 95.2%. These results suggest that, regardless of the surgical duration and blood loss in all fields of surgery, orthognathic surgery must be categorized in the highest risk group for glove perforation, following gynaecological and open lung surgery, due to the involvement of sharp objects.     

上颌平面偏斜对牙列中线与正中矢状面吻合度影响

目的:针对颌面部不对称畸形患者,在计算机上应用正颌手术模拟软件,重建三维头颅模型并模拟正颌手术,通过对术前上颌平面偏斜的角度和模拟正颌术后上颌牙列中线与正中矢状面夹角的分析,得出二者之间的关系,为正颌手术提供参考。方法:选择在中国医科大学附属口腔医院口腔颌面外科就诊的20位颌面部不对称畸形患者进行研究,首先用三维CT影像重建出头颅模型,测量上颌平面与水平参考面的夹角,再利用软件模拟上颌Le FortⅠ型截骨,测量上颌牙列中线与正中矢状面的夹角,最后应用统计学软件进行统计分析,得出两个角度间的关系。结果:颌面部不对称畸形患者,上颌平面和水平参考面的夹角与上颌牙列中线和正中矢状面夹角存在正相关的线性关系,经过统计学分析,得到上颌平面和水平参考面的夹角X与上颌牙列中线与正中矢状面夹角Y的直线回归方程,为Y=1.997+12.109X。结论:颌面部不对称畸形患者,上颌平面偏斜对牙列中线与正中矢状面的吻合度存在相关性,该相关性可为正颌手术的整复提供原则性的参考。     

812例牙外科正畸术的疗效观察

目的 探讨牙外科正畸术在矫治成年人牙He畸形中的临床价值。方法 对812例牙源性错He畸形患者，采用牙外科正畸术矫治。结果 术后3月、6月、1月的观察，总有效率90％，手术适应症选择及术者操作的熟练程度，决定了手术的成败。结论 牙外科正畸术对成年人牙He畸形的矫治具有临床实用价值。     

A mini-residency program in orthognathic surgery

A method of teaching major orthognathic surgical techniques is presented. One hundred hours of instruction in laboratory, practical, clinical, and operating room experiences were presented over two months, on alternate weekends. These intervals allowed for assimilation of new didactic material, readings, and study and laboratory exercises at home. Four teams of three oral and maxillofacial surgeons rotated to the operating rooms during each weekend session to experience hands-on training. The protracted period of follow-up observations enabled participants to witness most cases from start to finish and learn to anticipate and manage sequellae. Experienced oral and maxillofacial surgeons demonstrated a quick grasp of newer techniques of orthognathic surgery, and most translated the mini-residency experience into their practices.     

Practice patterns of oral and maxillofacial surgeons in Australia: 1990 and 2000

This study was undertaken to describe practice patterns of oral and maxillofacial surgeons in Australia and compare trends over time. All registered oral and maxillofacial surgeons in Australia were surveyed in 1990 and 2000 using mailed self-complete questionnaires. Data were available from 79 surgeons from 1990 (response rate = 73.8%) and 116 surgeons from 2000 (response rate = 65.1%). In both 1990 and 2000 the majority of surgeons worked 80+% of the time in the private sector (64.1 and 71.4%), had 80+% referrals from dental versus medical sources (74.0 and 74.7%), and had 80+% of patients from dentoalveolar rather than major maxillofacial surgery (70.7 and 69.7%). The percentage of dual qualified (dental plus medical degree) surgeons increased from 2.5% in 1990 to 17.1% in 2000 (P < 0.05; chi2). In 2000, surgeons who worked less than 80% in the private sector were more likely to report being overworked (57.9%) and that more surgeons were required in the public sector (65.0%) than those who worked 80% or more private (17.0 and 24.0%, respectively). Multivariate linear regressions of annual non-dentoalveolar surgical procedures per surgeon showed (P < 0.05) higher provision of implant (beta = 0.362), TMJ (beta = 0.267) and bone graft surgery (beta = 0.208) in 2000 compared to 1990, and higher provision of orthognathic (beta = 0.199), implant (beta = 0.194) and bone graft surgery (beta = 0.289) by dual qualified surgeons compared to those with only dental qualifications. Despite the mix of cases remaining predominantly dentoalveolar there was some change over time for selected non-dentoalveolar surgical procedures, with growth in the percentage of medically qualified surgeons and differences in surgery rates by qualification.
