Abstract

Background:  Muscles affected by postparetic synkinesis have imbalanced tonicity that limit perioral mimetic movement and inhibit the ability to smile. The depressor anguli oris (DAO) muscle has been a common myectomy target for the treatment of perioral synkinesis. While addition of buccinator myectomies to DAO myectomies has risen, no studies have analyzed the effects of buccinator myectomies. The goal of this study was to evaluate and compare the effects of a DAO myectomy with and without concomitant buccinator myectomy through objective facial metrics and subjective patient-reported outcomes.

Methods:  This study is a retrospective review of patients with postparetic synkinesis who underwent DAO myectomy (DAO myectomy group) or DAO myectomy with buccinator myectomy (DAO + Buccinator myectomies group). Outcomes included postoperative differences in objective smile measures (smile angle, excursion, and dental show) using validated software and patient-reported outcomes using the Facial Disability Index (FDI) questionnaire and a myectomy-specific questionnaire.

Results:  After chart review, 18 patients were included in the DAO myectomy group and 19 in the DAO + Buccinator myectomies group. There were no significant postoperative differences between the groups in (1) smile excursion, angle, or dental show at resting, closed smile, or open smile (p > 0.05), (2) FDI physical and social scores, p = 0.198 and 0.932, respectively, or (3) myectomy-specific questionnaire responses (p > 0.05).

Conclusion:  The addition of a buccinator myectomy to a DAO myectomy does not provide significant clinical benefit when compared with an isolated DAO myectomy, based on objective measures and subjective patient-reported outcomes.

瘫痪后的同步运动:下压角肌(DAO)切除术与下压角肌和颊肌切除术的客观和主观比较。
背景:受疼痛后同步肌影响的肌肉具有不平衡的强直性,从而限制了口周模仿运动并抑制了微笑能力。口角下压肌(DAO)一直是治疗口周肌张力障碍的常见肌肉切除目标。虽然在 DAO 肌肉切除术的基础上增加了颊舌肌切除术,但还没有研究对颊舌肌切除术的效果进行分析。本研究的目的是通过客观面部指标和患者主观报告结果,评估和比较在进行 DAO 肌肉切除术的同时进行和不进行颊侧肌肉切除术的效果:本研究是一项回顾性研究,研究对象是接受了DAO肌切除术(DAO肌切除术组)或DAO肌切除术联合颊侧肌切除术(DAO+颊侧肌切除术组)的麻痹性滑膜炎术后患者。结果包括术后使用有效软件进行的客观微笑测量(微笑角度、偏移和牙齿显示)的差异,以及使用面部残疾指数(FDI)问卷和颌骨切除术专用问卷进行的患者报告结果:经过病历审查,18 名患者被纳入 DAO 骨髓切除术组,19 名患者被纳入 DAO+Buccinator 骨髓切除术组。两组患者术后在以下方面无明显差异:1.微笑偏移、角度或静态、闭合微笑或开放微笑时的牙齿显示(P>.05);2.FDI生理和社交评分,分别为P=.198和P=.932;3.颌骨切除术特定问卷回答(P>.05):结论:根据客观测量和患者主观报告结果,与单独的DAO myectomy切除术相比,在DAO myectomy切除术的基础上增加颊侧myectomy切除术不会带来显著的临床益处。

期刊介绍: The Journal of Reconstructive Microsurgery is a peer-reviewed, indexed journal that provides an international forum for the publication of articles focusing on reconstructive microsurgery and complex reconstructive surgery. The journal was originally established in 1984 for the microsurgical community to publish and share academic papers. The Journal of Reconstructive Microsurgery provides the latest in original research spanning basic laboratory, translational, and clinical investigations. Review papers cover current topics in complex reconstruction and microsurgery. In addition, special sections discuss new technologies, innovations, materials, and significant problem cases. The journal welcomes controversial topics, editorial comments, book reviews, and letters to the Editor, in order to complete the balanced spectrum of information available in the Journal of Reconstructive Microsurgery. All articles undergo stringent peer review by international experts in the specialty.
