AIM
The aim of this study was to assess the electrical activity of temporalis and masseter muscles in children with cleft lip and palate (CLP) and pain-related temporomandibular disorders (TMD-P).
METHODS
The sample consisted of 31 CLP patients with a TMD-P (mean age 9.5 ± 1.8 years) and 32 CLP subjects with no TMD (mean age 9.2 ± 1.7 years). The children were assessed for the presence of temporomandibular disorders (TMD) using Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD). Electromyographical (EMG) recordings were performed using a DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) in the mandibular rest position and during maximum voluntary contraction (MVC).
RESULTS
The rest activity of the temporalis and masseter muscles was significantly higher in TMD-P group compared with non-TMD children. A significant decrease in temporalis muscle activity during MVC was observed in TMD-P patients. There was a significant increase in the Asymmetry Index for temporalis and masseter muscle rest activity in the TMD-P group.
CONCLUSION
Cleft children diagnosed with TMD-P have altered masticatory muscle activity, and this can affect their muscle function.
目的
本研究旨在评估唇腭裂（CLP）患儿及疼痛相关颞下颌关节紊乱病（TMD-P）患儿颞肌和咬肌的电活动情况。
方法
样本包括31例患有TMD-P的CLP患者（平均年龄9.5±1.8岁）和32例无TMD的CLP受试者（平均年龄9.2±1.7岁）。使用颞下颌关节紊乱病研究诊断标准（RDC/TMD）的轴I对儿童进行颞下颌关节紊乱病（TMD）评估。使用DAB蓝牙仪器（德国Zebris Medical GmbH公司）在下颌休息位和最大自主收缩（MVC）期间进行肌电图（EMG）记录。
结果
与无TMD的儿童相比，TMD-P组颞肌和咬肌的静息活动明显更高。在TMD-P患者中，观察到MVC期间颞肌活动显著降低。TMD-P组颞肌和咬肌静息活动的不对称指数显著增加。
结论
被诊断为TMD-P的腭裂患儿咀嚼肌活动发生改变，这可能会影响其肌肉功能。
