purpose: to evaluate the outcomes of ptosis surgery in patients with weak levator function using orbicularis oculi and frontalis muscles. methods: this prospective interventional case series study was conducted over 3 years on patients with ptosis and weak levator function (less than 4mm). in all cases, orbicularis oculi and frontalis muscles were used directly to correct the ptosis. success wa...

Figure 1. Preoperative photograph demonstrating severe ptosis on the right lid with levator function less than 5 mm (measured by blocking the action of the frontalis muscle). The patient is contracting his right frontalis muscle to keep his right eyelid open. Normal levator function is 11 mm.

OBJECTIVE Until recently, magnetic resonance was the only imaging method capable of assessing the levator ani in vivo. Three-dimensional (3D) ultrasound has recently been shown to be able to demonstrate the pubovisceral muscle. The aim of this study was to define the anatomy of the levator hiatus in young nulliparous women with the help of 3D ultrasound. METHODS In a prospective observational...

BACKGROUND Levator trauma is common in parous women. We have recently found a relationship with age at first vaginal delivery in women seen before and after childbirth. AIMS To examine women presenting with symptoms of pelvic floor disorders for such an association. METHODS Eight hundred and one women were prospectively seen for an interview, clinical examination (including for levator inte...

[Purpose] This study examined the measurement of the thickness of the transverse abdominal muscle in different tasks. [Subjects and Methods] The subjects were eleven healthy adult females. Thicknesses of transverse abdominal muscle were measured in seven tasks in the supine position. The tasks were: 1) Resting state, 2) Maximal contraction of transverse abdominal muscle, 3) Maximal contraction ...

OBJECTIVE Develop a method to quantify the cross-sectional area of the pubic portion of the levator ani muscle, validate the method in women with unilateral muscle defects, and report preliminary findings in those women. METHOD Multi-planar proton density magnetic resonance images of 12 women with a unilateral defect in the pubic portion of their levator ani were selected from a larger study ...

OBJECTIVE To estimate changes in levator hiatal dimensions after childbirth in women with and without ultrasonographically visible morphological abnormalities of the levator ani and to correlate those changes with delivery mode. METHODS A total of 296 nulliparous women were recruited. They were examined with four-dimensional translabial ultrasonography at 36-38 weeks of gestation and at 3-4 m...

OBJECTIVE Magnetic resonance imaging techniques have improved the study of female pelvic dysfunction. However, disagreements between magnetic resonance measurements and their derived 3-dimensional reconstructions were noted. We tested the hypothesis that these discrepancies stemmed from variations in magnetic resonance acquisition angle. STUDY DESIGN Images from the pelvis of the Visible Huma...

A young adult male equestrian sustained an avulsion of his levator ani muscle and its bony origin secondary to a horse landing on his groin. Avulsion of the levator ani muscle has, to our knowledge, only been described in obstetric related injuries. We describe the findings on CT imaging of this traumatic blunt injury.
