摘要

目的：本研究旨在评估教学医院使用传统模型手术进行上颌骨复位手术的准确性：共有 73 名患者接受了上颌骨单块 LeFort I 型截骨术和下颌骨双侧矢状劈开截骨术。通过计算机软件（Dolphin3D©）对术前和术后即时锥形束 CT 进行比较。评估了与垂直和水平参考线相对的上颌骨地标。测量了计划位置和实际位置之间的差异。以毫米为单位计算不同上颌运动的距离误差和实现比率（实现位移/计划位移*100）：结果：中线校正和前移是最准确的移动，其总平均距离误差分别为 0.53 毫米和 0.63 毫米，而后入和后退是最不准确的移动，其平均误差分别为 1.38 毫米和 1.76 毫米。只有后移运动的偏差值存在明显差异（P < .05）。虽然后移和下移倾向于矫正不足，但所有其他移动都矫正过度。随着上颌运动幅度的增加，精确度也随之降低。在严重移位（≥ 8 mm）时，准确度显著下降（P < .05）：结论：在教学医院中，传统的石膏手术和手工制作的中间夹板在大多数病例（84.6%）中都能获得准确且可接受的结果。上颌骨复位的准确性随着移位幅度的增加而降低。

Accuracy of maxillary repositioning surgery in teaching hospitals using conventional model surgery.

Purpose: The aim of this study was to assess the accuracy of maxillary repositioning surgery in teaching hospitals using conventional model surgery.

Materials and methods: A total of 73 patients undergoing single-piece LeFort I osteotomies in the maxilla and bilateral sagittal split osteotomies in the mandible were included in the study. Preoperative and immediate postoperative cone-beam CT were compared in computer software (Dolphin3D©). Maxillary landmarks relative to the vertical and horizontal reference lines were evaluated. The difference between the planned and achieved maxillary positions was measured. Distance error in millimeters and achievement ratio (achieved displacement/planned displacement*100) were calculated for different maxillary movements.

Results: Midline correction and advancement were the most accurate movements with an overall mean distance error of 0.53 mm and 0.63 mm respectively while posterior impaction and setback were the least accurate movements with 1.38 mm and 1.76 mm mean discrepancies, respectively. A significant difference was observed only in setback movement regarding the discrepancy value (P < .05). Although setback and down-graft movements tended to under-correction, all other movements were overcorrected. As the magnitude of maxillary movements increases, the accuracy decreases. In severe displacements (≥ 8 mm), the accuracy declines significantly (P < .05).

Conclusion: Classic cast surgery and manually fabricated intermediate splints in teaching hospitals yield accurate and acceptable results in the majority of cases (84.6%). The accuracy of maxillary repositioning decreases as the magnitude of displacement increases.

期刊介绍： Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
