摘要

简介:本研究旨在利用磁共振成像(MRI)和计算机断层扫描(CT)方法评估不同年龄组患者的颏下肌和咀嚼肌,并探讨肌肉形态、颞下颌关节(TMJ)结构和椎间盘移位之间的潜在关联。材料和方法:回顾性分析共185份MRI扫描,以评估双侧二腹肌、膝舌骨肌、下颌舌骨肌、翼状内侧肌、咬肌和翼状外侧肌的厚度。应用计算机断层扫描(CT)对颞下颌关节硬组织病变进行分类。采用Pearson相关系数分析肌肉厚度与TMJ结构的相关性,p < 0.05为差异有统计学意义。结果:研究人群女性110例,男性75例,平均年龄50.08±20.15岁。最大的年龄组是51-75岁(41%),其次是18-35岁(28%)。肌肉厚度与颞下颌关节结构有显著相关性:右二腹肌与右椎间盘髁位置有显著相关性(p = 0.02)。右下颌舌骨肌与右椎间盘髁位置有很强的相关性(p = 0.004)。左侧翼状内侧肌与左髁病变有显著相关性(p = 0.02)。左咬肌与左髁病变有显著相关性(p = 0.014)。髁突扁平化是最常见的病理,在58%的右髁和53%的左髁中观察到。41%的右侧tmj和34%的左侧tmj出现椎间盘移位。结论:本研究强调了咀嚼肌和颏下肌形态与TMJ结构之间的重要联系,表明肌肉功能可能在髁突定位和椎间盘对准中发挥作用。这些发现强调了在TMJ障碍(TMD)的诊断和治疗计划中需要进行全面的肌肉评估。

Magnetic Resonance Imaging of Submental and Masticatory Muscle Morphology and Its Relationship with Temporomandibular Joint Structures.

Introduction: This study aimed to evaluate the submental and masticatory muscles in patients of different age groups using magnetic resonance imaging (MRI) and computed tomography (CT) methods, and investigate potential associations between muscle morphology, temporomandibular joint (TMJ) structures, and disc displacement. Materials and Methods: A total of 185 MRI scans were retrospectively analyzed to assess the thickness of the digastric, geniohyoid, mylohyoid, medial pterygoid, masseter, and lateral pterygoid muscles bilaterally. TMJ hard tissue changes were classified using computed tomography (CT). Correlations between muscle thickness and TMJ structures were analyzed using Pearson correlation coefficients, with statistical significance set at p < 0.05. Results: The study population included 110 females and 75 males, with a mean age of 50.08 ± 20.15 years. The largest age group was 51-75 years (41%), followed by 18-35 years (28%). Significant correlations were observed between muscle thickness and TMJ structures as follows: Right digastric muscle showed a significant association with right disc-condyle position (p = 0.02). Right mylohyoid muscle exhibited a strong correlation with right disc-condyle position (p = 0.004). Left medial pterygoid muscle was significantly correlated with left condyle pathology (p = 0.02). Left masseter muscle showed a significant correlation with left condyle pathology (p = 0.014). Condylar flattening was the most frequent pathology, observed in 58% of right condyles and 53% of left condyles. Disc displacement was present in 41% of right TMJs and 34% of left TMJs. Conclusions: This study highlights the important associations between masticatory and submental muscle morphology and TMJ structures, suggesting that muscle function may play a role in condylar positioning and disc alignment. These findings emphasize the need for comprehensive muscle evaluation in TMJ disorder (TMD) diagnosis and treatment planning.
