External auditory canal atresia (EACA) is a common otologic condition. Etiology can vary from congenital to acquired causes. It causes considerable difficulty to the patient. Bilateral ear canal atresia in children can lead to speech delays due to hearing impairment caused by this condition. Though easily diagnosed it is one of the most difficult conditions to treat. Acquired conditions can affect any age group. Restenosis following treatment is very common. This article focuses on the treatment of EACA due to different etiologies and emphasizes on special points of surgical treatment and follow up...

BACKGROUND: Tsetse flies (genus Glossina) are large blood-sucking dipteran flies that are important as vectors of human and animal trypanosomiasis in sub-Saharan Africa. Tsetse anatomy has been well described, including detailed accounts of the functional anatomy of the proboscis for piercing host skin and sucking up blood. The proboscis also serves as the developmental site for the infective metacyclic stages of several species of pathogenic livestock trypanosomes that are inoculated into the host with fly saliva...

INTRODUCTION: We present an interesting case of a 55 year-old male with a large left chest mass after significant cutaneous bleeding. CT angiogram of the chest revealed arteriovenous malformation with blood supply from subbranches of the left subclavian artery, left internal mammary artery and left external carotid artery. Measuring 5.0x14.0x10.8cm, the mass extended superior to the clavicle and inferior to the third rib with medial and lateral borders at the level of the clavicular head and coracoid, respectively...

Preoperative assessment of tissue anatomy and accurate surgical planning is crucial in conjoined twin separation surgery. We developed a new method that combines three-dimensional (3D) printing, assembling, and casting to produce anatomic models of high fidelity for surgical planning. The related anatomic features of the conjoined twins were captured by computed tomography (CT), classified as five organ groups, and reconstructed as five computer models. Among these organ groups, the skeleton was produced by fused deposition modeling (FDM) using acrylonitrile-butadiene-styrene...

BACKGROUND: The lateral femoral condyle (LFC) flap is a vascularized bone flap based on the superior lateral genicular artery (SLGA). Harvest technique for this flap has not yet been demonstrated. The purpose of this study was to better delineate the blood supply to the bone and skin of this flap to allow for a safe and effective harvest. MATERIALS AND METHODS: Twenty-three lower extremities were injected with latex or a mixture of latex and barium sulfate. The SLGA was identified and dissected, documenting the course, diameter, anatomical relations, length, and branches...

Reduction mammaplasty is the volumetric reduction in the bulk of the breast. Techniques have evolved from primarily reducing the breast bulk to reducing with emphasis on functional and aesthetic outcome. The deeper understanding of the surgical anatomy of the breast has guided this development. While Paulus Aegina (sixth century AD), Dieffenbach (1848) and Gaillard-Thomas (1882) set the pace in glandular reduction; Pousson (1897) and Dehner (1908) focused on breast ptosis. It took quite some time before the enigma of the vascularization to the nipple areolar complex could be solved...

Recent advances in laser surgery and our understanding of wound healing have ushered in a new era of trauma and burn scar management. Traditional therapy has centered around scar excision followed by primary closure or tissue replacement with flaps and grafts. This approach represents a perpetuation of the common fallacy that extensive scar improvement requires extensive surgical intervention. Laser surgery in conjunction with pharmacotherapy and minor tissue-conserving surgery produces well-healed and remodeled existing tissue that provides the most natural appearance and function of the skin...

Mandible angle is considered to be a consistently palpable external landmark for the identification of cervical spinal level by a radiographic study. But this anatomical study aimed to determine the positional relationship between mandible angle and cervical spinal level in cadavers. In this study, the cervical spine of 10 adult cadavers with intact head and neck structure, including 6 males and 4 females, was dissected, and the position of mandible angle (MA) relative to the corresponding cervical spinal level was measured when the head was fixed in the flexion, anatomy position, and extension...

OBJECTIVE: Fournier's gangrene is an infective necrotizing fasciitis of the perineal, genital and perianal regions. Treatment includes aggressive surgical debridement that often results in extensive loss of genital skin. Skin grafts may be used for reconstruction but skin grafting of the male genitalia is diffucult because the penis and scrotum are mobile and deformable. A variety of methods are used to secure skin graft to recipient beds. We used negative pressure therapy (NPT) to secure skin grafts and improve skin graft taking...

INTRODUCTION: Mandibular reconstruction performed after virtual planning has become more common during recent years. The gold standard for extensive mandibular reconstruction is of course a fibular free flap. In designing an osteomyocutaneous fibula flap, poor planning, aberrant anatomy and/or inadequate perforator vessels are the most frequent causes of complications and may force the surgeon to modify the flap design, explore the contralateral leg or harvest an additional microvascular flap...

In the treatment of traumatic injuries, burns, and ulcers of the eye, inadequate epithelial tissue healing remains a major challenge. Wound healing is a complex process involving the temporal and spatial interplay between cells and their extracellular milieu. It can be impaired by a variety of causes including infection, poor circulation, loss of critical cells, and/or proteins, and a deficiency in normal neural signaling (e.g., neurotrophic ulcers). Ocular anatomy is particularly vulnerable to lasting morbidity from delayed healing, whether it be scarring or perforation of the cornea, destruction of the conjunctival mucous membrane, or cicatricial changes to the eyelids and surrounding skin...

Reconstruction of partial ear defects represents one of the most challenging areas within reconstructive surgery of the head and neck. Each case of auricular reconstruction is unique and warrants a systematic approach that accounts for defect size and location, the quality of the surrounding skin, patient preference, and operator experience. In this article, the authors outline different reconstructive approaches for defects of the upper-, middle-, and lower-third of the auricle. The relevant anatomy is discussed in detail...

INTRODUCTION: Minimally invasive procedures have gained great importance among the treatments for benign prostate hyperplasia (BPH) due to their low morbidity. Prostate artery embolization has emerged as a safe and effective alternative for patients with large volume BPH, not suited for surgery. MATERIALS AND METHODS: Low adverse events rates have been reported following prostate artery embolization and may include dysuria, urinary infection, hematuria, hematospermia, acute urinary retention and rectal bleeding...

BACKGROUND: One promising surgical treatment of lymphedema is the VLNT. Lymph nodes can be harvested from different locations; inguinal, axillary, and supraclavicular ones are used most often. The aim of our study was to assess the surgical anatomy of the lateral thoracic artery lymph node flap. MATERIALS AND METHODS: In total, 16 lymph node flaps from nine cadavers were dissected. Flap markings were made between the anterior and posterior axillary line in dimensions of 10 × 5 cm...

PURPOSE: Most dose calculations for HDR brachytherapy treatments are based on the AAPM-TG43 formalism. Because patient's anatomy, heterogeneities and applicator shielding are not considered, the dose calculation based on this formalism is inaccurate in some cases. Alternatively, Collapsed Cone (CC) methods as well as Monte Carlo (MC) algorithms belong to the model based dose calculation algorithms, which are expected to improve the accuracy of calculated dose distributions. In this work, the performance of a CC algorithm, ACE in Oncentra Brachy 4...

Reconstruction of an aesthetically acceptable and functional upper lip requires a careful consideration of the transverse and vertical soft tissue, muscle and skin, deficiency. This review focuses on the reconstructive aspects of the upper lip.The functional anatomy of the upper lip is considerably complex and includes paired muscles in addition to the orbicularis, elevators of both the upper lip and commissure. The muscular action of facial expression recruits different sets of these paired muscles. Unlike the aesthetic uniform appearance of the lower lip commissure to commissure, the upper lip aesthetics can be divided into a central, the philtrum unit, and a lateral upper lip unit...

C Villa, K B Olsen, S H Hansen
Post-mortem CT scanning (PMCT) has been introduced at several forensic medical institutions many years ago and has proved to be a useful tool. 3D models of bones, skin, internal organs and bullet paths can rapidly be generated using post-processing software. These 3D models reflect the individual physiognomics and can be used to create whole-body 3D virtual animations. In such way, virtual reconstructions of the probable ante-mortem postures of victims can be constructed and contribute to understand the sequence of events...

REVIEW
Stuart R Chipkin, Fred Kim
Transgender people have a gender that is not in agreement with their birth sex. Previous barriers, including lack of provider knowledge, have created significant healthcare disparities for this population. Recent societal changes are increasing the numbers of transgender people seen by primary care practitioners. Ten key principles are provided to help primary care practitioners create more welcoming environments and provide quality care to transgender patients. Overall, all members of the healthcare team (primary and specialty) need to become aware of the transition process and maintain communication regarding risks, benefits, and goals...

The stability of the patellofemoral joint relies on the tenuous interplay of soft tissue and bony factors. Anatomic risk factors for instability include a shallow trochlea, an abnormally lateral tibial tubercle position, patella alta, hypermobility, or a secondary injury to the medial patellofemoral ligament (MPFL). There is an increasing interest in restoring normal anatomy to achieve stability, and at times more than 1 abnormality exists. This article describes the technique for combining a tibial tuberosity transfer and an MPFL reconstruction...
