To analyze the relationships between MRI image changes of lateral pterygoid muscle (LPM), disc position and condylar mobility.
Twenty Class II patients were chosen and MRI images of LPM were taken. The relationships between MRI image changes of LPM, disc position and condylar mobility were analyzed.
The rate of MRI image changes of LPM in Class II patients was about 45%. No significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.
MRI image changes of LPM in Class II patients was common but no significant correlations were found between MRI image changes of LPM, condylar mobility and disc position.
分析翼外肌（LPM）的MRI图像变化、盘状位置与髁突活动度之间的关系。
选取20例安氏II类患者，拍摄翼外肌的MRI图像。分析翼外肌的MRI图像变化、盘状位置与髁突活动度之间的关系。
安氏II类患者翼外肌的MRI图像变化率约为45%。翼外肌的MRI图像变化、髁突活动度与盘状位置之间未发现显著相关性。
安氏II类患者翼外肌的MRI图像变化较为常见，但翼外肌的MRI图像变化、髁突活动度与盘状位置之间未发现显著相关性。
