Comparison of the Levator Hiatal Area

Abstract

Objective: To determine the relationship of the levator hiatal area
 among nulliparous, primiparous, and multiparous women so that
 we can assess the prevalence of avulsion.
 
 Method: A cross-sectional study design was used by evaluating the
 transperineal ultrasound results of all nulliparous, primiparous, and
 multiparous women in the Obstetrics and Gynecology Clinic of
 Dr. Cipto Mangunkusumo hospital from May to December 2015. We
 analyzed the data through SPSS using one way ANOVA to compare
 the levator hiatal dimension among the groups of women during
 Valsava maneuver and at rest.
 
 Result: There were significant differences in levator hiatal area
 among nulliparous, primiparous, and multiparous women during
 Valsalva maneuver and at rest, which the mean (SD) was 22.26
 (5.45) cm2 (p=0.028) and 10.70 (2.26) cm2 (p=0.012), respectively.
 Levator ani muscle avulsion was occurred in 1 out of 46 (2.2%)
 women from the primiparous and multiparous group.
 
 onclusion: There are significant differences in levator hiatal area
 during Valsalva and at rest among the groups.
