OBJECTIVES
The main objective of this study was to compare the actual distribution and thickness of aponeuroses in cadavers with the distribution and thickness as determined by means of magnetic resonance imaging for the sake of evaluating magnetic resonance imaging as a diagnostic modality for assessing masseter muscle aponeuroses.
STUDY DESIGN
The aponeuroses of 26 masseter muscles from 13 intact cadavers were examined by magnetic resonance imaging.
RESULTS
The ratio of concordance between gross findings and magnetic resonance imaging findings was 99.0%, although depiction of thin parts of the aponeuroses on magnetic resonance imaging was poor.
CONCLUSIONS
Magnetic resonance imaging was useful as a diagnostic modality in the assessment of masseter muscle aponeuroses. Aponeuroses were distributed throughout almost the entire masseter muscle, although almost no aponeuroses were seen below the lower half of the anterior margin. This was thought to be a characteristic finding of masseter aponeuroses.
目的
本研究的主要目的是比较尸体中腱膜的实际分布和厚度与通过磁共振成像确定的分布和厚度，以评估磁共振成像作为评估咬肌腱膜的诊断方法。
研究设计
对13具完整尸体的26块咬肌的腱膜进行了磁共振成像检查。
结果
大体检查结果与磁共振成像结果的一致性比例为99.0%，尽管磁共振成像对腱膜薄部分的显示较差。
结论
磁共振成像作为评估咬肌腱膜的诊断方法是有用的。腱膜几乎分布于整个咬肌，但在前缘下半部以下几乎未见腱膜。这被认为是咬肌腱膜的一个特征性表现。
