Abstract

Background: This study aimed to investigate the optimal surgical techniques in reduction malarplasty by comparing the difference between the L-shaped osteotomy with vertical and oblique bone resection.

Methods: A total of 120 patients who visited the authors' department for L-shaped osteotomy with either vertical (group I) or oblique bone resection (group II) from 2015 to 2021 were reviewed retrospectively. The preoperative and postoperative spiral computed tomographic data were analyzed. The preoperative computed tomographic data were also used to simulate the virtual and model surgery.

Results: The results showed that a broken bridge-like structure with a bony gap of 2.86 ± 1.03 mm at the zygomatic arch root was observed in group I, and a mortice-and-tenon joint structure with a bone overlap of 2.28 ± 0.58 mm was formed in group II. The zygoma in group I displaced significantly in the vertical direction and horizontal direction during the follow-up. Simultaneously, the incidence of complications was higher in group I. In the mechanism analysis through virtual and model surgery, the zygomatic segment was shifted anteriorly and inferiorly in group I, and a bony gap was detected at the zygomatic arch root. Conversely, a superior and posterior movement was performed in group II and it maintained the zygomatic complex integral with bone overlap at the zygomatic arch root on repositioning.

Conclusion: This study suggested that L-shaped osteotomy with oblique bone resection could be the optimal choice for reducing zygomatic prominence.

Clinical question/level of evidence: Therapeutic, III.

L型颧骨缩小术与斜切或垂直切除术:哪一种是最佳选择?
背景:本研究旨在通过比较 "L "形截骨术与垂直截骨术和斜向截骨术的差异,探究减瘤成形术的最佳手术方法:本研究旨在通过比较L形截骨与垂直和斜向骨切除术之间的差异,研究还原假体成形术的最佳手术技术:回顾性分析2015年至2021年到我科就诊的120例L形截骨加垂直(Ⅰ组)或斜向骨切除(Ⅱ组)的患者。对术前和术后螺旋计算机断层扫描(CT)数据进行了分析。术前 CT 数据还被用于模拟虚拟手术和模型手术:结果显示:Ⅰ组颧弓根部出现了2.86±1.03 mm的断桥状骨间隙结构,Ⅱ组颧弓根部形成了2.28±0.58 mm的骨重叠的榫接结构,Ⅲ组颧弓根部出现了2.86±1.03 mm的断桥状骨间隙结构,Ⅳ组颧弓根部形成了2.28±0.58 mm的骨重叠的榫接结构。随访期间,Ⅰ组颧骨在垂直方向和水平方向均有明显移位。同时,Ⅰ组并发症的发生率较高。通过虚拟手术和模型手术进行机制分析,Ⅰ组的颧骨节段向前方和下方移位,在颧弓根部发现骨性间隙。相反,Ⅱ组进行了上后移动,并在复位时保持了颧骨复合体的整体性,颧弓根部有骨重叠:结论:这项研究表明,L 型截骨术配合斜骨切除术是减少颧骨突出的最佳选择。

期刊介绍: For more than 70 years Plastic and Reconstructive Surgery® has been the one consistently excellent reference for every specialist who uses plastic surgery techniques or works in conjunction with a plastic surgeon. Plastic and Reconstructive Surgery® , the official journal of the American Society of Plastic Surgeons, is a benefit of Society membership, and is also available on a subscription basis. Plastic and Reconstructive Surgery® brings subscribers up-to-the-minute reports on the latest techniques and follow-up for all areas of plastic and reconstructive surgery, including breast reconstruction, experimental studies, maxillofacial reconstruction, hand and microsurgery, burn repair, cosmetic surgery, as well as news on medicolegal issues. The cosmetic section provides expanded coverage on new procedures and techniques and offers more cosmetic-specific content than any other journal. All subscribers enjoy full access to the Journal''s website, which features broadcast quality videos of reconstructive and cosmetic procedures, podcasts, comprehensive article archives dating to 1946, and additional benefits offered by the newly-redesigned website.
