BACKGROUND AND AIM: The auriculotemporal nerve (ATN) is one of the branches of the mandibular division of the trigeminal nerve, which gives rise to many branches to the retromandibular and temporal regions. Of these, the superficial temporal branch can occasionally be the cause of migraine headaches and auriculotemporal neuralgia. The purpose of this study was to elucidate the anatomy of the superficial temporal branch, which has never been described in detail. METHODS: A total of 14 sides of cadaveric heads were used for this study...

Three-dimensional (3D) printing is a rapidly advancing technology in the field of surgery. This article reviews its contemporary applications in 3 aspects of surgery, namely, surgical planning, implants and prostheses, and education and training. Three-dimensional printing technology can contribute to surgical planning by depicting precise personalized anatomy and thus a potential improvement in surgical outcome. For implants and prosthesis, the technology might overcome the limitations of conventional methods such as visual discrepancy from the recipient's body and unmatching anatomy...

In recent years there has been an exponential increase of fillers use in aesthetic medicine. The popularity of this anti-wrinkle product is based on their capacity to offer significant improvement in the aesthetic field, particularly to skin rejuvenating processes with non-invasive and less expensive techniques, if compared to the surgical methods (i.e. surgical lifting). The great number of fillers on the market is composed of a large heterogenic number of biomaterials. The aim of this review was to provide an overview and a classification of the filling materials that are most commonly used...

BACKGROUND: The two major perforators supplying the superficial circumflex iliac artery perforator (SCIP) flap are the medial (superficial) and lateral (deep) perforators but lacks detailed description. The purpose of this study was to clarify the anatomy. MATERIAL AND METHOD: In a prospective analysis of 142 patients, CT angiograms of 284 SCIP regions were evaluated and 142 SCIP flaps were surgically correlated. The origin of the SCIA, the origin of the medial perforator, the location where it penetrates the deep fascia, and its pattern of pathway after penetration of the superficial fascia were evaluated...

BACKGROUND: -Spinal arteriovenous shunts are a common spinal vascular disorder. However, they can have a misleading clinical presentation and poor prognosis. They are classified into 4 types according to shunt points and drainage route, among which extradural arteriovenous fistula (eAVF) is the most rare, comprising only 1% of all spinal arteriovenous shunts. Here, we report an extremely rare case of coexistent eAVF at the craniocervical junction and soft tissue arteriovenous malformation (AVM) within the same metamere...

The vermilion zone of the lips (also called red lip or zone of Klein) has peculiar characteristics, different from the surrounding skin, which make it one of the most important parts of the lips. It can be considered a tactile organ, with an essential role in the body's anatomy and functions. Together with the lips, the vermilion zone represents one of the typical characteristics of mammals and its evolutionary appearance seems to be linked to the source of nutrition of these animals (especially breastfeeding), to the articulation of sounds, to their facial expression and to their sexual function...

Fitness is known to have beneficial effects on brain anatomy and function. However, the understanding of mechanisms underlying immediate and long-term neurophysiological changes due to exercise is currently incomplete due to the lack of tools to investigate brain function during physical activity. In this study, we used time-domain near infrared spectroscopy (TD-NIRS) to quantify and discriminate extra-cerebral and cerebral hemoglobin concentrations and oxygen saturation (SO2) in young adults at rest and during incremental intensity exercise...

BACKGROUND: In the normal human penis, the glans wings merge in the midline ventrally, but are separated by the 'septum glandis' in conjunction with the frenulum. The frenulum is also included in the formation of the distal (glanular and subcoronal) urethra, which has a special part known as the 'fossa navicularis'. This has inspired a hypospadias repair technique that simulates the development of the glanular and subcoronal urethra, which can be incorporated into the repair of all cases of hypospadias...

BACKGROUNDS: Various flaps elevated from the palm have been widely used for finger and hand reconstruction. Recently, perforator-based free flaps or venous free flaps have received popularity due to several advantages. The cutaneous venous system has been chosen as the circulatory outlet when designing and harvesting the flap from the palmer area due to the small size and thin nature of the flap. However, there have been few descriptions about the anatomy of the palmar cutaneous veins...

Among extinct ichthyosaurs the Jurassic forms Ichthyosaurus and Stenopterygius share a number of anatomical specializations with lamnid sharks, characterized in the white shark, Carcharodon carcharias These features allow their inclusion within the mode of high-speed thunniform swimming to which only two other equally distinctive phylogenetic groups belong, tuna and dolphins-a striking testaments to evolutionary convergence. Jurassic ichthyosaurs evolved from reptiles that had returned to the sea (secondarily adapted) about 250 million years ago (MYA) while lamnid sharks evolved about 50 MYA from early cartilaginous fishes (originating ca...

One of the most impressive soft tissue injuries is the facial degloving, normally associated with industrial machines and traffic accidents. This injury is characterized by the separation of the skin and cartilage from the bones, compromising the soft tissues correlated in the trauma area, nerves, and blood vessels. A 28-year-old patient, male, was referred to Araçatuba's Santa Casa Hospital, after a motorcycle accident, hitting his face on the sidewalk. The patient was conscious, oriented, denying fainting and unconsciousness during the accident, and complaining of pain in the nasal region of the face...

BACKGROUND: Conventional reconstructive methods fail to achieve satisfactory results in total eyelid defect cases. Vascularized composite tissue allotransplantation might provide both good appearance and function for these patients. The structure of the eyelid is exceptional because it simultaneously consists of skin, connective tissue, the striated muscle, fiber structure, aponeuroses, and mucosa. Thus, before clinical application of eyelid allotransplantation, more experiments are needed to clarify the impact of ischemia, immunal suppressive agents, and deinnervation effects on these sophisticated structures...
