BACKGROUND: Blepharoplasty is a common aesthetic surgery performed worldwide. In Asians, too high eyelid folds after blepharoplasty cause an unsatisfactory aesthetic outcome that is difficult to correct. In this article, the authors propose surgical techniques to correct the high eyelid fold after blepharoplasty. METHODS: During a 4-year period, 213 secondary blepharoplasties were performed to correct high folds. Postoperative results were reviewed, graded, and analyzed...

BACKGROUND: The ability to correct unnatural-appearing, high, and deep double eyelid folds has been limited by the lack of redundant upper eyelid skin and the presence of prior incision line scars in patients. METHODS: From January 2000 to September 2011, 256 patients with high and deep double eyelid folds underwent our fold-lowering procedure. The first dissection was made at the superficial layer between the orbicularis oculi muscle and orbital septum/retroorbicularis oculi fat...

BACKGROUND: Sciatica has been classically described as pain in the back and hip with radiation in the leg along the distribution of the sciatic nerve, secondary to compression or irritation of the sciatic nerve. Spinal abnormality being the most common etiology, is one of the most common indications for MRI of the lumbosacral spine. Here we describe imaging findings secondary to a supralevator perianal abscess causing irritation of the sciatic nerve, which was diagnosed on MRI of the lumbosacral spine...

Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men...

INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle rehabilitation is a widely utilized, but often challenging therapy for pelvic floor disorders, which are prevalent in older women. Regimens involving the use of appendicular muscles, such as the obturator internus (OI), have been developed for strengthening of the levator ani muscle (LAM). However, changes that lead to potential dysfunction of these alternative targets in older women are not well known. We hypothesized that aging negatively impacts OI architecture, the main determinant of muscle function, and intramuscular extracellular matrix (ECM), paralleling age-related alterations in LAM...

OBJECTIVES: Postlaparoscopic shoulder pain (PLSP) remains a common problem after laparoscopies. The aim of this study was to investigate the correlation between pressure pain threshold (PPT) of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT. MATERIALS AND METHODS: The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery...

Myotonia congenita is a non-dystrophic skeletal muscle disorder characterized by muscle stiffness and an inability of the muscle to relax after voluntary contraction caused by a mutation in the gene encoding skeletal muscle chloride channel-1 (CLCN1). We encountered a case of Thomsen disease with ptosis. A short tau inversion recovery MR imaging demonstrated high-intensity lesions in the levator palpebrae superioris muscles. Molecular genetic testing revealed a heterozygosity for the c.1439C>A (p.P480H) mutation in the CLCN1 gene...

Introduction: Defects of the levator ani muscle complex could represent a pathophysiological link between vaginal birth trauma and urogynecological symptoms many years later. The aim of our study was to determine the prevalence of levator ani muscle defects using 3D or 4D ultrasound and palpation in urogynecological patients. Material and Methods: Urogynecological patients were retrospectively investigated using 3D or 4D ultrasound. Clinical examination consisted of palpation and 3D or 4D imaging of the levator ani muscle...

BACKGROUND: The trapezius muscle consists of three parts that are capable of functioning independently. Its superior part together with the levator scapulae and rhomboids elevate the shoulder, the middle part retracts the scapula, while the inferior part lowers the shoulder. OBJECTIVES: The present study aimed to supplement numerical data and to provide growth dynamics of the trapezius in the human fetus. MATERIAL AND METHODS: Using methods of anatomical dissection, digital image analysis (NIS Elements AR 3...

The aim of this study was to examine the superoinferior extension of the postlevator aponeurosis fat pad in the upper eyelids of Japanese cadavers. Twenty-six upper eyelids (12 right and 14 left) from 15 Japanese cadavers (6 men and 9 women; average age at death, 82.1 years) were used in this experimental anatomical study. After an orbital exenteration, the tissues were cut sagittally through the center of the orbit, and the superoinferior extension of the postlevator aponerosis fat pad was microscopically examined on the sections...

Compression of the dorsal scapular nerve (DSN) is associated with pain in the upper extremity and back. Even though entrapment of the DSN within the middle scalene muscle is typically the primary cause of pain, it is still easily missed during diagnosis. The purpose of this study was to document the DSN's anatomy and measure the oblique course it takes with regard to the middle scalene muscle. From 20 embalmed adult cadavers, 23 DSNs were documented regarding the nerve's spinal root origin, anatomical route, and muscular innervations...

INTRODUCTION AND HYPOTHESIS: During vaginal delivery, the levator ani muscle (LAM) undergoes severe deformation. This stress can lead to stretch-related LAM injuries. The objective of this study was to develop a sophisticated MRI-based model to simulate changes in the LAM during vaginal delivery. METHODS: A 3D finite element model of the female pelvic floor and fetal head was developed. The model geometry was based on MRI data from a nulliparous woman and 1-day-old neonate...

Vaginal delivery is the primary cause of levator ani muscle injury, which is in turn the leading factor contributing to pelvic floor disorders including pelvic organ prolapse and urinary stress incontinence. Existing biomechanical models of childbirth have provided some understanding of pelvic floor function during delivery and have helped in the investigation of preventative strategies. The modeling frameworks for childbirth simulation are described with emphasis on (1) the recent advances in medical imaging quality and computational power; (2) improvements in the anatomical representation of the pelvic floor and fetal head; (3) more realistic boundary conditions for delivery; and (4) mechanical properties determined from experiments...
