摘要

的相关性。痉挛性脑瘫是脑瘫最常见的形式之一,其中肌肉强直,包括下颌肌肉,存在。到目前为止,对于肌肉强直没有通用的算法。诊断是基于主诉和肌电图研究的数据。本文描述并证明了将超声和激光多普勒血流测量(LDF)纳入附加诊断方法的基本原理。材料和方法。我们对84例脑瘫患儿进行了超声和LDF检查,研究了咀嚼肌的状态。超声检查确定咬肌和颞肌的结构和厚度,检测触发点和浸润部位。LDF在休息和咬合测试后进行,可以评估咀嚼肌肉的储备能力。我们将收到的数据与一组相同年龄的健康受试者进行比较。超声参数和LDF数据与对照组不同。超声检查首次发现触发点,患者无主诉。由肌肉细胞损伤引起的充血是脑瘫患儿局部血流的特征。咬合试验结果证明了咀嚼肌代偿能力,临床医生在制定治疗方案时应考虑到这一点。接收到的数据将帮助牙医诊断和治疗肌肉强直症,从而防止病理恶化。

Ultrasound and laser Doppler flowmetry assessment of jaw muscle hypertonia in children with cerebral palsy
Relevance. Spastic cerebral palsy is one of the most common forms of cerebral palsy, in which muscular hypertonia, including jaw muscles, is present. To date, there is no universal algorithm for muscle hypertonia. The diagnosis is made based on complaints and data from an electromyographic study. This paper describes and proves the rationale for including ultrasound and laser Doppler flowmetry (LDF) in additional diagnostic methods.Material and methods. We examined 84 children with cerebral palsy using ultrasound and LDF to study the state of the mastication muscles. The ultrasound examination determined the structure and thickness of the masseter and temporal muscles and detected trigger points and the infiltration site. LDF was performed both at rest and after an occlusal test, which allows assessing the reserve capacities of the mastication muscles. We compared the received data with a group of healthy subjects of the same age.Results. Ultrasound parameters and LDF data differed from the control group. The ultrasound examination revealed trigger points for the first time without patients’ complaints. Congestion caused by damage to muscle cells is characteristic of the local blood flow in children with cerebral palsy. The results of the occlusal test evidenced the mastication muscle compensation abilities, which clinicians should consider during treatment planning.Conclusion. The received data will help dentists diagnose and treat muscle hypertonia, which will prevent pathology deterioration.
