INTRODUCTION: Although there have been many studies of the arterial cerebral blood supply, only seven have described the optic chiasm (OC) blood supply and their results are contradictory. The aim of this study was to analyze the extrinsic and intrinsic OC blood supply on cadaveric specimens using dissections and microcomputer tomography (Micro-CT). MATERIALS AND METHODS: Thirteen human specimens were dissected and the internal or common carotid arteries were injected with red latex, China Ink with gelatin or barium sulfate...

INTRODUCTION: Marfan syndrome (MFS) is a rare hereditable disorder of connective tissue caused by mutations in the fibrillin-1 gene FBN1. Timely diagnosis of MFS is essential to prevent life-threatening cardiovascular complications; nevertheless it can be difficult owing to the phenotypic variability of the syndrome. No clear quantitative definition of facial abnormalities associated with MFS is available. The aim of this study was to improve the definition of the facial phenotype associated with MFS and to verify the usefulness of a 3D noninvasive quantitative approach for its early recognition...

PURPOSE: To investigate the topographical relationship between the frontal branch of the superficial temporal artery (FSTA) and the temporal branch of the facial nerve (TFN) with the aim of preventing nerve injury during FSTA biopsy. METHODS: Fifty-seven hemifaces of 33 cadavers were dissected. Vertical lines drawn to the lateral orbital margin (LOM) and the superior root of the helix were used as the anterior and posterior reference positions, respectively. Horizontal lines drawn through the supraorbital margin and lateral canthus were used as the superior and inferior reference points, respectively...

Imaging in the major planes (horizontal, coronal, and sagittal) of the uterus is important for determining anatomy and allowing the findings to be standardized, and for evaluating and diagnosing different pathological conditions in clinical practice. Examination of the coronal plane is an important step in identifying uterine pathologies and their relationships to the endometrial canal. Three-dimensional ultrasound reveals the normal anatomy better and improves the depiction of abnormal anatomy, as the coronal plane of the uterus can easily be obtained using 3D reconstruction techniques...

PURPOSE: Loss of ejaculation can follow transurethral resection of the prostate (TURP). Periverumontanal prostate tissue is preserved in ejaculation-preserving TURP (ep-TURP). Knowledge of ejaculatory duct anatomy in relation to the prostatic urethra can help in ep-TURP. This was evaluated in cross-sections of the prostate using a 3D model to determine a safe zone for resecting the prostate in ep-TURP. MATERIALS AND METHODS: A 3D reconstruction of the ejaculatory ducts was developed on the basis of six prostate gland cross-sections...

INTRODUCTION: Dermatomes are an important component of medical curricula and clinical practice. In addition to the intrinsic complexity of dermatome maps, their discrepancies in the literature make their learning among students even more difficult. These discrepancies are particularly evident in the lower deltoid ("regimental badge" area) and upper back. The aims of our study were firstly to identify and compare published versions of the dermatome map focusing on depictions of the "regimental badge" area and upper back, secondly to assess the perceived confidence and knowledge of dermatomes among medical students, and finally to create and introduce a simplified dermatome map...

BACKGROUND: The general microscopic characteristics of nerves are described in several textbooks of histology, but the specific microanatomies of most nerves that can be blocked by anesthesiologists are usually less well known. Our objective was to evaluate the 3D reconstruction of nerve fascicles from optical projection tomography images (OPT) and the ability to undertake an internal navigation exploring the morphology in detail, more specifically the fascicular interconnections. METHODS: Median and lingual nerve samples were obtained from five euthanized piglets...

INTRODUCTION: Fibromyalgia is a disorder characterized by pain and a spectrum of psychological comorbidities, rendering treatment difficult and often a financial burden. Findings regarding diagnosis, prevalence, comorbidities, and potential pathophysiological links are discussed herein. Fibromyalgia is a complex disorder and there are specific criteria that patients must meet for diagnosis, including scores on fibromyalgia questionnaires, commonalities of age, gender, menopause status, sleep disturbances, and mood symptoms...

INTRODUCTION: Inflammatory etiologies are becoming increasingly recognized as explanations of some neuropathies, especially those occurring in the perioperative period. Although "brachial neuritis" is known to affect extraplexal nerves, accessory nerve palsy following median sternotomy has been attributed to stretch on the nerve. To better elucidate stretch as a potential cause, a cadaveric study was performed. MATERIALS AND METHODS: Two patients who developed accessory nerve palsy following median sternotomy are presented to illustrate features consistent with the diagnosis of a perioperative inflammatory neuropathy...

#11
Colin W Moore, Jacob Fanous, Charles L Rice
INTRODUCTION: Surgical studies describe the palmaris longus (PL) as a synergist in thumb abduction, which may facilitate its use in restoring thumb function using opponensplasty. However, beyond morphological descriptions and isometric thenar abduction strength measures, the evidence supporting the PL as a thenar synergist in-vivo is limited. The purpose here was to determine whether the PL provides synergistic contributions to thenar musculature by: (1) recording PL muscle activity using indwelling electromyography (EMG) during thumb movements; and (2) quantifying changes in PL muscle architecture using ultrasonography...

INTRODUCTION: Transgender reassignment surgeries have become a major topic of interest within the last decade. Although there are numerous surgical techniques for male-to-female reassignment, a physician must assess each patient's anatomy and past medical history to determine the most suitable technique. Additionally, patient preference is important. The neovaginal constructive technique most commonly used in male-to-female reassignment surgery is penile skin inversion, but various other techniques and tissues can also be used including pelvic peritoneum, buccal mucosa, and bowel...

REVIEW
Richard A Santucci
BACKGROUND: Radial forearm free flap phalloplasty (RFFP) is the current standard of care for most FTM gender confirmation surgeries. This procedure is associated with a rate of urethral stricture as high as 51%, which falls only to 23-35% even among the most experienced contemporary surgeons. While some modifications have been proposed to combat this high complication rate, it still remains a major source of lasting morbidity. METHODS: Literature review of RFFP literature...

As the United States of America becomes more socially diverse, it is more important now than ever for health care providers to become more aware of their patients' social identities. It is imperative that providers engage with their patients and see how each of them identifies personally in relation to social construction terminology. As with the terminology of human anatomy, there is a vast and diverse vocabulary concerning the anatomy of society, which is also clinically relevant to health care providers...

R Klaus, D Royer, M E Stabio
Traditionally, medical schools have maintained collections of tissues/organs to engage students in anatomy. Such collections are often stored in volatile and toxic preservatives. Plastination is an alternative tissue preservation technique in which polymers replace water and lipids resulting in benign, dry, and anatomically authentic specimens. Plastination is used in medical education internationally; however, its use within U.S. medical schools is not widely discussed in the anatomical literature. This study aimed to determine the knowledge, use, and perceptions of plastination as a teaching tool among U...

INTRODUCTION: In transgender surgery, the ideal neophallus is one that: (a) is constructed using a reproducible procedure, (b) possesses tactile and erogenous sensation, (c) is large and rigid enough (naturally, or using a prosthesis) to permit penetrative intercourse, (d) leaves acceptable donor site morbidity, (e) results in esthetically satisfactory appearance, and (f) allows for voiding while standing. The musculocutaneous latissimus dorsi (MLD) flap has favorable results in the area of neophalloplasty...
