Abstract
Objective: This study aims to systematically review and meta-analyze the electromyographic activity of masticatory muscles in cleft palate and non-cleft patients, and identify influencing factors.
Design: Systematic Review and Meta-analysis.
Patients and exposures: Patients with cleft lip/ palate.
Comparison: Patients without CL/P.
Main outcome measures: Electrical activity of masseter and temporalis muscles at rest and during peak activation.
Results: After a comprehensive search in MEDLINE, Web of Science, EMBASE, Scopus, and Cochrane's CENTRAL up to December 2022, without language or date restrictions. Eligible trials were selected based on the PECO question and assessed for bias using Cochrane's ROBINS-E tool. Eight clinical trials with 474 participants were included in the review. Then relevant data was extracted from included studies using customized forms. A random-effects meta-analysis was performed to combine the results of the studies, meta-analyses showed that CL/P patients have elevated electrical activity in the masseter (P = .01) and temporalis (P = <.01) muscles at rest compared to non-cleft control patients. During maximum bite force, cleft patients exhibited a statistically significant decrease in electrical activity in both the masseter (P = .03) and temporalis (P = <.01) muscles.
Conclusions: According to our meta-analysis, cleft patients exhibited increased resting muscle activity but decreased activity during maximum bite force, indicating reduced efficiency of masticatory muscles compared to non-cleft patients. These differences can be attributed to anatomical variations, compensatory mechanisms, and previous treatments.
目的:本研究旨在对腭裂和非腭裂患者咀嚼肌肌电活动进行系统回顾和meta分析，并找出影响因素。设计:系统评价和荟萃分析。患者及暴露对象:唇腭裂患者。比较:无CL/P患者。主要观察指标:咬肌和颞肌在休息和激活高峰时的电活动。结果:在MEDLINE, Web of Science, EMBASE, Scopus和Cochrane's CENTRAL中综合检索至2022年12月，无语言或日期限制。根据PECO问题选择符合条件的试验，并使用Cochrane的ROBINS-E工具评估偏倚。8项临床试验纳入了474名参与者。然后使用定制表格从纳入的研究中提取相关数据。随机效应荟萃分析结合研究结果，荟萃分析显示CL/P患者在咬肌(P = 0.01)、颞肌(P = P = 0.03)和颞肌(P = 0.03)的电活动升高。结论:根据我们的荟萃分析，唇裂患者在最大咬合力时肌肉活动增加，但活动减少，这表明与非唇裂患者相比，咀嚼肌肉的效率降低。这些差异可归因于解剖变异、代偿机制和以前的治疗。
