Abstract Infrahyoid muscles are usually supplied by muscular arteries, originating from the superior and inferior thyroid artery and the internal thoracic artery. In this work, we reported a unilateral anatomical variation of the branching pattern of the lingual artery, which was observed during dissection studies at the University of Brescia. We found an accessory branch arising from the root of the lingual artery that run down medially and supplied the infrahyoid muscles. A similar...

Introduction The appearance of the face is one of the most important factors influencing our perception of beauty. However, few studies have attempted to quantitate what one perceives as beauty. Therefore, this study was conducted with the goal of providing physicians with anatomical data that demonstrate which facial traits most influence our perception of one's attractiveness. Material and methods In the first phase of the study, faces of 60 participants (30 males and 30 females) were photographed....

Introduction The arachnoid membranes’ anatomy is a controversial topic in the literature, and the rhomboid membrane at the craniovertebral junction is an element of this system that has been described poorly. Hence, our study's objective was to examine this membrane's anatomy and histology. Materials and Methods 45 fresh formalin‐fixed human cadaveric heads were examined, and anatomic dissections and histologic examinations using standard staining methods were performed. Results The...

It is generally accepted that primary spontaneous pneumothorax (PSP) is found mostly in tall, thin young males. However, the precise etiology of PSP is unclear. We compared some thoracic structural angles of PSPs and controls in young males to determine the predominant factor. CT data of 43 male PSPs (age 21.88 ± 5.30) and 30 controls (age 21.47 ± 5.47) were collected. The angle of thoracic vertebrae slope (∠α), sternal slope angle (∠β), and tracheal‐sternal stem angle (∠γ) were measured in the sagittal...

INTRODUCTION We aimed to assess the relationship of the rotational position of the aortic root to its underlying ventricular support, and to the position of the inferior margin of the membranous septum, which serves as a surrogate of the atrioventricular conduction axis. MATERIALS AND METHODS We analyzed 40 normal heart specimens (19 children, 21 adults). The inferior margin of the membranous septum was measured relative to the virtual basal ring. The rotational position of the aortic root...

Introduction Multiple medical interventions require percutaneous instrumentation of the anterior abdominal wall, all of which carry a potential for vascular trauma. We assessed the presence, position and size of the anterior abdominal wall superior and inferior (deep) epigastric arteries to determine the safest site with respect to vascular anatomy of the rectus sheath. Materials & Methods In a review of 100 arterial phase, contrast‐enhanced abdominal computed tomography scans, anterior...

Introduction A standard relationship of the median nerve to neighbouring tendons in the carpal tunnel has been described but descriptions of normal variations are limited. The aim of this study is to describe the variation in position of the median nerve within the carpal tunnel and the variability in relation to adjacent tendons on clinical MR studies. Methods A retrospective study was performed, analyzing 37 wrist MR examinations performed on a 3 T MR machine. Primary endpoints involved...

Objective Our goal was to clarify the relationship between the superior wall of the mandibular canal and the presence of teeth. We also sought to study the structural changes of the mandibular canal after tooth loss. Methods Twenty sides from ten dry mandibles derived from six males and four females were used for this study. The age of the specimens at the time of death ranged from 57 to 91 years. The mandibles were cut in the midline resulting in twenty hemi‐mandibles. The presence of teeth...

Introduction For various clinical/surgical procedures, it is important to accurately understand the location of the sinuatrial node (SAN). Therefore, this study's goal was to develop a new and simple method to visualize the SAN in human hearts. Methods Sixteen formalin‐fixed human hearts were used in the study. After the epicardium was removed, the fat tissue on the myocardium's surface was brushed and removed in a solution of 40°C water with a surfactant to show the SAN's location. Once the...

INTRODUCTION Our goal was to evaluate a new air dissection technique for the spaces of the head and neck using fresh‐frozen cadavers. METHODS Eight sides from four fresh‐frozen Caucasian cadavers were used in this study. Compressed air was initially placed into the pterygomandibular space while simultaneously observing the spaces of the head and neck. Subsequently, the pterygomandibular space on the contralateral side of the specimen was insufflated and observations made. For these methods,...

Abstract Purpose Several skull-base foramina including foramen meningo-orbitale, craniopharyngeal canals, canaliculus innominatus, foramen vesalius, palatovaginal canals, and canalis basalis medianus are visible on cone-beam computed tomographs. A good understanding of the anatomical variants of these foramina is important to accurately diagnose fractures, understand the paths that infections may take, and identify associated anomalies....
