AbstractMyofascial pelvic pain (MFPP) of pelvic floor muscles is a common cause of chronic pelvic pain (CPP). The pathological mechanisms and treatments of MFPP are complex and still unclear until now. The levator ani muscle (LAM) is the major pelvic floor muscle. The purpose of this study was to examine the fascia and attachment of LAM through the electromyogram (EMG) and cadaver dissection. Electrophysiological stimulation of the obturator fascia above the arcus tendinous levator ani (ATLA) could trigger contraction and electrophysiological changes in LAM insertion. The LAM of embalmed adult cadavers was examined especially in the area above the ATLA. Some skeletal muscle fibers were found above the ATLA within the obturator fascia and were confirmed by Masson’s trichrome section staining. Our electromyography (EMG) and anatomical data implied that the attachment of LAM aponeurosis extended beyond ATLA to the inferior border of the superior ramus of the pubic bone. The new discovered attachment of LAM could provide a reference position for clinical diagnosis and treatment of MFPP or CPP.

Abstract Background Pelvic floor dysfunction is known to be among the principal factors influencing public health, regarding frequency, cost and effect on women’s quality of life. Radiographic assessment of the pelvic floor function and anatomy plays a vital role in the recognition of pelvic floor defects. The aim of this study is to detect the postpartum-related levator ani muscle changes thus defining the relationship between the vaginal deliveries and the etiology of pelvic floor dysfunction in order to provide guidelines to decrease the incidence of pelvic floor injuries during parturition and guide the treatment plan. Results There was a significant difference in the puborectalis muscle thickness between the case and control groups in the right puborectalis (P value ≤ 0.001) and in the left puborectalis (P value (≤ 0.001) as well as significant midpoint thickness (P value = 0.03) with 46.2% puborectalis muscle injury in the case group compared with none in the control group. Conclusion Pelvic floor MRI is highly recommended as it is a contrast-free modality that allows for both anatomical and functional analysis. Its incorporation in the routine postpartum assessment will allow early detection of abnormalities even in asymptomatic cases thus ensuring proper management and preventing the development of pelvic floor dysfunction predisposed to by repeated vaginal deliveries.

Levator Ani Muscle Avulsion

Pelvic floor dysfunction (PFD) due to vaginal delivery is related to tear of levator ani muscle (LAM) that potentially lead to the impairment of quality of life among women. A number of attempts to predict LAM injury after vaginal delivery had been conducted. This study aims to appraise the accuracy of several prediction index determining LAM injury after vaginal delivery. We conducted a search in Cochrane Library®, Pubmed®, and Medline® with the keywords of “pelvic floor dysfunction” AND “vaginal delivery” AND “prediction.” Critical appraisal determining the validity, importance, and applicability (VIA) was conducted by 2 independent authors. After 6 weeks to 3 months’ duration of follow up, the incidence of LAM avulsion was varied from 15.4% to 35.6% from three studies. Multivariate analysis showed that forceps delivery, OASIS, and active second stage (OR 3.8; 3.1; 1.61; respectively) as the most influential factors for LAM incidence. Maternal age and time spent in active pushing were also contributed to LAM incidence. OASIS and second stage of labor could be used as the most influential components of prediction index for LAM incidence. Prediction indexes for LAM incidence are developed. OASIS and second stage of labor are acknowledged as two most influential variables among three appraised studies.

AbstractThe male pelvic floor is a complex structure formed by several muscles. The levator ani muscle and the perineal muscles are important components of the pelvic floor. The perineal muscles comprise the external anal sphincter, bulbospongiosus, superficial transverse perineal muscles, and ischiocavernosus. Although the connections of the muscles of the pelvic floor have been reported recently, the anatomical details of each muscle remain unclear. In this study, we examined the male pelvic floor to clarify the connection between the muscles related to function. Fifteen male pelvises were used for microscopic dissection, and three male pelvises were used for histological examination. On the lateral aspect, the perineal muscles were connected to each other. Bundles of the levator ani muscle extended to connect to the perineal muscles. In addition, the extended muscle bundle from the levator ani muscle and the perineal muscles surround the external urethral sphincter. On the medial aspect, the levator ani muscle and the external anal sphincter form the anterior and posterior muscular slings of the anal canal. The connection between the perineal muscles and levator ani muscle indicates a possible close relationship between the functions of the urethra and anus.
