OBJECTIVE: To evaluate pelvic floor biometry 3-5 years after first delivery. The effect of a second delivery and mode of delivery were studied. METHODS: Women, who had been assessed at first pregnancy, 8 weeks postnatally and one year after delivery, were invited for follow-up. Positions of the bladder neck (BN), cervix, anorectal junction and hiatal area (HA), were evaluated by translabial ultrasound. The effects of parity, mode of delivery and levator ani muscle (LAM) avulsion were studied...

The development of the nervous system involves the overproduction of synapses but connectivity is refined by Hebbian activity-dependent axonal competition. The newborn skeletal muscle fibers are polyinnervated but, at the end of the competition process, some days later, become innervated by a single axon. We used quantitative confocal imaging of the autofluorescent axons from transgenic B6.Cg-Tg (Thy1-YFP)16 Jrs/J mice to investigate the possible cooperation of the muscarinic autoreceptors (mAChR, M1-, M2- and M4-subtypes) and the tyrosine kinase B (TrkB) receptor in the control of axonal elimination after the mice Levator auris longus (LAL) muscle had been exposed to several selective antagonist of the corresponding receptor pathways in vivo...

Pelvic floor protection is an issue of increasing relevance. This article sought to summarize the session at last year's annual meeting of the German Society of Gynecology and Obstetrics (DGGG) in Stuttgart (10/2016) called "Urogynecology 2020-what is the optimal rate of cesarean section-does urogynecology have to deal with Obstetrics?". The main focus was set on the two important anatomical structures, the levator ani muscle and the anal sphincters. Operative vaginal delivery, epidural anesthesia, and episiotomy are subject to discussion...

A diagnostic feature of temnospondyls is the presence of an open palate with large interpterygoid vacuities, unlike the closed palate of most other early tetrapods, in which the vacuities are either slit-like or completely absent. Attachment sites on neurocranium and palatal bones in temnospondyls allow the reconstruction of a powerful m. retractor bulbi and a large, sheet-like m. levator bulbi that formed the elastic floor of the orbit. This muscle arrangement indicates that temnospondyls were able to retract the eyeballs through the interpterygoid vacuities into the buccal cavity, like extant frogs and salamanders...

We describe a rare case of a 31-year old woman with bilateral ptosis due to localized amyloidosis. She referred a nine-year history of ptosis and surgical treatment with frontalis suspension three years previously. Following complete ophthalmological examination and evaluation of the ptosis we carried out tarsal and fornix biopsy, which revealed accumulation of a weakly eosinophilic amyloid positive substance. We performed surgical correction using the levator aponeurosis-Müller's muscle complex re-adaptation technique and amyloid substance debulking in all the palpebral layers in the left eye...

BACKGROUND: Involutional blepharoptosis is the most common type of acquired blepharoptosis. The etiology is believed to be the degeneration of the levator aponeurosis, and levator superioris muscle function was believed to be normal. However, there are a few studies analyzing levator function (LF) in involutional blepharoptosis. Our study aimed to access the LF abnormality in involutional blepharoptosis and analyze the correlation between LF and ptosis severity in involutional blepharoptosis in Taiwan...

A 78-year-old woman complained of gradual, painless onset of horizontal binocular diplopia associated with progressive axial weakness. Physical examination revealed esotropia that was greater at distance than at near vision, bilateral levator dehiscence, and normal abducting saccadic speeds. Given the age of the patient and compatible clinical findings, the diagnosis of Sagging Eye Syndrome (SES) was made. However, further work-up with a muscle biopsy suggested Sporadic Late-Onset Nemaline Myopathy (SLONM) as the cause of her progressive muscle weakness...

BACKGROUND: Myofascial Trigger points (MTrPs) may be caused or aggravated by many factors, such as mental stress associated with exams and impaired posture. AIM: To compare the prevalence and sensitivity of MTrPs, and forward head position (FHP) during exam period vs. mid-semester among physical therapy students. METHODS: 39 physical therapy students were palpated for MTrPs in neck and shoulder muscles and were photographed laterally for FHP measurement during the academic semester and during the academic examination period...

INTRODUCTION AND HYPOTHESIS: The etiology of pelvic organ prolapse (POP) likely includes over-distension or tears (avulsion) of the levator ani muscle. However, there is a lack of studies evaluating the association between symptoms of POP and these factors. This study was designed to determine the association between POP symptoms and clinical prolapse stage on the one hand, and pelvic floor functional anatomy on the other hand. METHODS: This prospective observational study included 258 patients seen at a tertiary urogynecological unit with symptoms of POP as defined by pertinent ICIQ questions...

REVIEW
Kyla Joubert, Jonathan A Laryea
Rectal prolapse is a debilitating condition with a complex etiology. Symptoms are most commonly prolapse of the rectum and pain with bowel movements or straining, with worsening fecal incontinence over time due to progressive stretching of the anal sphincters. Physical findings are fairly consistent from patient to patient-most notably diastasis of the levator ani muscles, deep pouch of Douglas, redundant sigmoid colon, a mobile mesorectum, and occasionally a solitary rectal ulcer. Evaluation includes a physical exam or imaging demonstrating the prolapse, and evaluating for other causes of pelvic floor dysfunction...

Full-thickness rectal prolapse, or procidentia, is the passage of the full-thickness wall of the rectum beyond the anal sphincters. This condition results in pain and fecal incontinence which greatly impairs the quality of life of those afflicted. It is associated with several anatomic abnormalities, including decreased anal sphincter tone, levator muscle diastasis, and a deep anterior cul-de-sac. The diagnosis of rectal prolapse is made based on physical examination, although several other modalities are used to provide additional information about the patients' condition...

Background In cases of blepharoptosis, the upper eyelid either cannot or can only be elevated insufficiently. The aetiology may be myogenic, aponeurotic, neurogenic, mechanical, or traumatic. The most common cause of congenital ptosis is myogenic, due to the improper development of the levator muscle. Methods Frontalis suspension operation as a technique of correction often uses silicone slings or fascia lata. On the basis of 3 cases, we present our method using palmaris longus tendon. Results In all 3 cases, intra- and postoperative courses were without adverse events and all cases are still relapse-free...

A 53-year-old male presented with a chief complaint of dyschezia.Lower gastrointestinal endoscopy confirmed the presence of a type II tumor in the lower part of the rectum, and a biopsy detected a well-differentiated adenocarcinoma.As invasion of the prostate and levator muscle of the anus was suspected on diagnostic imaging, surgery was performed after preoperative chemotherapy.With no clear postoperative complications, the patient was discharged 26 days after surgery. After 24 months, the number of urination ranged from 1 to 6, with a Wexner score of 6 and a mild desire to urinate in the absence of incontinence...

PURPOSE: The aim of this study was to clarify the anatomical relationship of the procerus with the nose, especially focusing on the transverse part of the nasalis, the nasal ala, and the levator labii superioris alaeque nasi (LLSAN). MATERIALS AND METHODS: The 53 faces from Korean cadavers were examined anatomically. RESULTS: The procerus originated from the superficial and deep layers in all specimens. Some fibers of the lateral part of the superficial layer extended to connect to the transverse part of the nasalis, while other such fibers extended to attach to the skin of the upper nasal ala in all specimens...

Both the Müller muscle-conjunctiva resection (MMCR) and levator advancement (LA) procedures can be used to manage ptosis in patients with good levator function. The aim of this article is to evaluate the efficacy and cosmetic outcomes of the two procedures. The clinical records of 29 consecutive eyelids of 26 patients undergoing MMCR and 30 eyelids of 23 patients undergoing LA were analysed. Eleven (42%) in the LA group and 9 (39%) in the MMCR group were male. The preoperative eyelid measurements were significantly different in the LA compared to the MMCR groups, in terms of palpebral aperture (PA) (6...

Facial musculature is divided into masticatory muscles, i.e. M. masseter and M. buccalis, with bony insertions and smaller facial muscles involved in facial expression, which insert into bone and skin. There are four fixed osteocutaneous points of the face, i.e. zygomatic (Mac Gregor), mandibular (Furnas), orbital (Psillakis), and masseteric with an antigravitational effect and functional role in facial expression (1,2). In other body parts, the direct insertion of muscle fibers into skin has not been reported...

BACKGROUND: Pelvic organ prolapse affects half of vaginally parous women. Several animal models are used to study its pathophysiology and treatment. Sheep are interesting because they develop spontaneously prolapse with similar risk factors as women and can be used for vaginal surgery. This study describes ovine pelvis anatomy and compares it to women's pelvis to provide anatomical tools for translational researchers. METHODS: MRI, pelvic dissections, and histology were used for detailed macro- and microscopic analysis of relevant anatomical structures in 6 nulliparous ewes...

Nasal tip reconstruction can be very challenging. It requires close attention to skin texture, colour and thickness matching, with the respect of the nasal aesthetic units and symmetry. Flaps are usually preferred to skin grafts where possible. Based on different donor areas, various flaps have been described for reconstruction of this region. Here we present a new V-Y myocutaneous island flap based on the levator alae nasi muscle (LAN muscle) blood supply. This flap may represent an alternative to the nasalis myocutaneous sliding V-Y flap previously described by Rybka...
