Levator plate descent correlates with levator ani muscle deficiency

Aims Measurements such as the minimal levator hiatus dimension, levator plate angle, iliococcygeal angle, and anorectal angle have been used for assessing the impact of levator damage on static and dynamic imaging features. The primary aim of this study was to investigate the association between lev...

Description
Summary:Aims Measurements such as the minimal levator hiatus dimension, levator plate angle, iliococcygeal angle, and anorectal angle have been used for assessing the impact of levator damage on static and dynamic imaging features. The primary aim of this study was to investigate the association between levator ani muscle deficiency (LAD) and the position of the levator plate. Methods 3D endovaginal ultrasounds of 186 women were reviewed. The levator ani muscle groups, the puboanalis, puborectalis, and pubovisceralis, were scored for abnormalities, (0 no defect and 3 total absence of the muscle). The levator plate descent angle, minimal levator hiatus dimensions, and the anorectal angle were measured. Levator plate descent towards the perineum was assessed and correlated with levator ani muscle deficiency. Results The correlation between puborectalis scores and minimal levator hiatus area, anorectal angle and levator plate descent angle were 0.43 (P
