目的：比较肛提肌横截面积作为脱垂和肌肉缺陷status.METHODS的功能：30名妇女脱垂和30名妇女正常盆腔支持被选中从一个正在进行的病例对照研究脱垂。对于两组中的每一组，10名妇女从三个类别中选择提肌缺陷的严重程度：无，轻微，和重大仰卧位磁共振扫描确定。使用这些扫描，使用建模程序（313 Slicer）制作提肛肌的三维（3D）模型，并使用另一个程序I-DEAS计算耻骨部分垂直于肌纤维方向的横截面。结果：与无缺陷组相比，有严重缺陷的女性提上睑肌腹侧部分横截面积减少36%，有轻微缺陷的女性提上睑肌腹侧部分横截面积减少29%（P
OBJECTIVE: Compare levator ani cross-sectional area as a function of prolapse and muscle defect status.METHODS: Thirty women with prolapse and 30 women with normal pelvic support were selected from an ongoing case-control study of prolapse. For each of the two groups, 10 women were selected from three categories of levator defect severity: none, minor, and major identified on supine magnetic resonance scans. Using those scans, three-dimensional (3D) models of the levator ani muscles were made using a modeling program (313 Slicer), and cross-sections of the pubic portion were calculated perpendicular to the muscle fiber direction using another program, I-DEAS. An analysis of variance was performed.RESULTS: The ventral component of the levator muscle of women with major defects had a 36% smaller crosssectional area, and women with minor defects had a 29% smaller cross-sectional area compared with the women with no defects (P
