摘要

目的：：近年来，三件式上颌骨截骨术的数量不断增加，但相关文献仍存在争议。本研究的目的是评估这种手术方式与一片式上颌骨截骨术相比的骨骼稳定性：这项回顾性队列研究包括 39 名接受 Le Fort I 上颌骨截骨术的患者，分为两组：第一组（三件式，22 人）和第二组（一件式，17 人）。每名患者的三次锥形束计算机断层扫描（T1，手术前；T2，手术后；T3，随访）用于评估骨骼的三维变化：在手术变化（T2-T1）方面，只有第 1 组的组内差异具有统计学意义，犬齿区域的平均差异为 3.09 毫米，后部区域的平均差异为 3.08 毫米。各组之间或组内手术稳定性无明显差异。组间差异的平均值为 0.05 毫米（后区）和-0.39 毫米（犬齿区）：我们的研究结果表明，单件式和三件式上颌骨截骨术的术后骨骼稳定性相似。

Is three-piece maxillary segmentation surgery a stable procedure?

Objective: : The number of three-piece maxillary osteotomies has increased over the years; however, the literature remains controversial. The objective of this study was to evaluate the skeletal stability of this surgical modality compared with that of one-piece maxillary osteotomy.

Methods: : This retrospective cohort study included 39 individuals who underwent Le Fort I maxillary osteotomies and were divided into two groups: group 1 (three pieces, n = 22) and group 2 (one piece, n = 17). Three cone-beam computed tomography scans from each patient (T1, pre-surgical; T2, post-surgical; and T3, follow-up) were used to evaluate the three-dimensional skeletal changes.

Results: : The differences within groups were statistically significant only for group 1 in terms of surgical changes (T2-T1) with a mean difference in the canine region of 3.09 mm and the posterior region of 3.08 mm. No significant differences in surgical stability were identified between or within the groups. The mean values of the differences between groups were 0.05 mm (posterior region) and -0.39 mm (canine region).

Conclusions: : Our findings suggest that one- and three-piece maxillary osteotomies result in similar post-surgical skeletal stability.

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
