PURPOSE: The endoscopic trans-eustachian approach (ETETA) is a less invasive approach to the infratemporal fossa (ITF), providing superior exposure compared to traditional transcranial approaches. The anatomy of the pharyngotympanic (eustachian) tube and adjacent neurovascular structures is complex and requires in-depth knowledge to safely perform this approach. We present a cadaveric and radiological assessment of critical anatomic considerations for ETETA. METHODS: Six adult cadaveric heads were dissected alongside examination of 50 paranasal sinus CT scans...

PURPOSE: The tensor fasciae latae (TFL) muscle is supplied by the lateral femoral circumflex artery (LCFA), arising from the deep femoral artery. However, it has been noted that there is also a consistent vascular anastomotic network. The aim of this study was to describe the accessory vascularization of the TFL muscle through a descriptive anatomical study, in order to hypothesize the feasibility of harvesting a TFL flap in the event of an injury to the main pedicle. In addition, we illustrate this hypothesis with a successful clinical case of Scarpa freconstruction following ligature of the deep femoral artery...

PURPOSE: Pelvic gynecological surgeries, whether for malignant or benign conditions, frequently result in functional complications due to injuries to the autonomic nervous system. Recognizing the deep uterine vein (DUV) as an essential anatomical reference can aid in preserving these structures. Despite its significance, the DUV is infrequently studied and lacks comprehensive documentation in Terminologia Anatomica. This research endeavors to elucidate a detailed characterization of the DUV...

REVIEW
Soo-Bin Kim, Hyewon Hu, Hyungkyu Bae, Kyu-Ho Yi
Hollow temples are not typically considered aesthetically pleasing, and hollowness worsens with the aging process. When filling this region with fillers, there are several anatomical considerations, with injection techniques varying depending on the layer targeted. Specifically, injections between the superficial temporal fascia and the superficial layer of the deep temporal fascia are performed using a cannula, while periosteal layer injections involve the use of a needle to reach the bone before inserting fillers...

The occurrence of variations in human arterial branching of the upper limb has been commonly reported in peer-reviewed literature. However, the variability of upper limb arterial patterns may be underappreciated in medical practice, which can result in clinical and surgical errors. Here we report a case of a rare, unilateral arterial variation of the left upper limb of a 76-year-old Caucasian male cadaver, discovered during a routine educational dissection. Observed characteristics of the variation include a high brachial artery bifurcation into a superficial brachioulnoradial artery and brachial artery continuing as the interosseous artery and then a bifurcation of the superficial brachioulnoradial artery into a superficial radial and a superficial ulnar artery, which eventually contribute to the formation of the superficial palmar arch...

PURPOSE: A right aortic arch (RAA) is a rare vascular anomaly that often coexists with an aberrant left subclavian artery (ALSA). Due to the rarity of RAA, the development of an ALSA is not well understood. METHOD: We describe a case in which a 58-year-old man who was scheduled to undergo posterior decompression and fusion surgery for thoracic ossification of the posterior longitudinal ligament from Th1 to Th3 was found to have a RAA and an ALSA. RESULTS: Preoperative computed tomography angiography demonstrated a RAA and an ALSA...

Intracranial arterial anatomy is lacking for most mammalian and non-mammalian model species, especially concerning the origin of the basilar artery (BA). Enhancing the knowledge of this anatomy can improve animal models and help understanding anatomical variations in humans. We have studied encephalic arteries in three different species of birds and eight different species of mammals using formalin-fixed brains injected with arterial red latex. Our results and literature analysis indicate that, for all vertebrates, the internal carotid artery (ICA) supplies the brain and divides into two branches: a cranial and a caudal branch...
