Abstract

Objective: This study aimed to investigate the effects of structured orofacial muscle rehabilitation training (OMRT) on the recovery of facial expression muscles in patients with skeletal Class II malocclusion after orthognathic surgery.

Study design: This randomized controlled trial enrolled 56 skeletal Class II malocclusion patients who underwent orthognathic surgery. The intervention group received structured OMRT, while the control group received standard postoperative care. Preoperative and postoperative assessments were performed at postoperative day 2, 14, 1 month, and 3 months, including linear angle measurements and relevant recovery indices. Data were analyzed using IBM SPSS 25.0 and R 4.1.2 software.

Results: The OMRT group exhibited significant improvements in facial function indices, specifically ChL-ChR, Ls-Li, and ∠ChL-Sn-ChR at one month postsurgery, with values either close to or aligned with preoperative levels. The recovery curve demonstrated rapid improvement from postoperative day two to one month, indicating that early structured training was associated with enhanced facial expression recovery, improved self-image, and faster psychological and functional restoration.

Conclusion: Structured OMRT significantly improves the recovery of facial expression muscles in skeletal Class II malocclusion patients following orthognathic surgery. These findings provide valuable clinical insights and may inform rehabilitation strategies for this patient population.

结构化口面肌康复训练对骨ⅱ类错颌正颌术后面部表情肌恢复的影响。

目的：探讨结构化口面肌康复训练（OMRT）对骨ⅱ类错颌正颌术后面部表情肌功能恢复的影响。研究设计：这项随机对照试验招募了56例接受正颌手术的骨骼II类错颌患者。干预组采用结构化的OMRT，对照组采用标准的术后护理。分别于术后第2天、第14天、第1个月和第3个月进行术前和术后评估，包括线性角度测量和相关恢复指标。采用IBM SPSS 25.0和R 4.1.2软件对数据进行分析。结果：OMRT组术后1个月面部功能指标（ChL-ChR、Ls-Li、∠ChL-Sn-ChR）均有显著改善，与术前水平接近或一致。从术后第2天到第1个月，恢复曲线显示快速改善，表明早期结构化训练与增强面部表情恢复，改善自我形象以及更快的心理和功能恢复有关。结论：结构化OMRT可显著改善骨ⅱ类错颌患者正颌手术后面部表情肌的恢复。这些发现提供了有价值的临床见解，并可能为该患者群体的康复策略提供信息。

期刊介绍： Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology is required reading for anyone in the fields of oral surgery, oral medicine, oral pathology, oral radiology or advanced general practice dentistry. It is the only major dental journal that provides a practical and complete overview of the medical and surgical techniques of dental practice in four areas. Topics covered include such current issues as dental implants, treatment of HIV-infected patients, and evaluation and treatment of TMJ disorders. The official publication for nine societies, the Journal is recommended for initial purchase in the Brandon Hill study, Selected List of Books and Journals for the Small Medical Library.
