The normal flexibility in morphology and topography of body structures may be termed as an anatomical variation. This manuscript, aims to present a unique discovery of 'coronoid foramina' bilaterally along with bilateral accessory foramina over the 'lateral aspect of the ramus of the mandible' which has never been seen or documented in the literature so far in a live patient. It is noteworthy to realize a trait of phylogenetic context in these discoveries.

PURPOSE: The aim of the study was to investigate the anatomy and histology of Linburg-Comstock variation, or the anomalous connection between flexor pollicis longus and flexor digitorum profundus to the index finger, in Thai population. METHODS: One hundred and thirty cadaveric upper limbs were dissected. Skin and superficial fascia on the anterior distal forearm and hand were removed. The tendons of the flexor pollicis longus and flexor digitorum profundus to the index finger were identified for the possible occurrence of the intertendinous connection...

PURPOSE: The extensor indicis proprius (EIP) is a muscle of the forearm that originates from the posterior surface of the ulna and the adjacent interosseous membrane and attaches to the index finger. Many anatomical variations of this muscle have been reported in the literature. The extensor digitorum brevis manus (EDBM) is a variant muscle found on the back of the wrist and hand. These muscle variants should be considered in the context of clinical syndromes and reconstructive hand surgery...

PURPOSE: The aim of this study was to determine whether the alar fascia is a distinct layer of the deep cervical neck fasciae. The present study also aimed to elucidate the anatomical limits of this fascia. METHODS: Neck dissections of ten adult cadavers were performed, layer by layer, in the retropharyngeal region, under a powered operating microscope. Detailed dissections revealed the anatomical limits of the deep neck fasciae. Histological descriptions were also performed on large tissue samples collected from three cervical dissections...

The glenohumeral ligaments (GHLs), localized thickenings of the anterior joint capsule, are important passive stabilizers of the shoulder joint. A 29-year-old man was admitted for evaluation of left shoulder pain. The conventional magnetic resonance (MR) imaging showed a thickened anterior labroligamentous complex. MR arthrography revealed a multiplication anomaly of all the GHLs. The purpose of this study was to demonstrate the MR arthrography findings of this unusual anatomic variation of the GHLs.

PURPOSE: To determine the frequency of circumportal pancreas (CP), and accompanying ductal and vascular anatomy variations. METHODS: Thin-section multidetector computed tomography of 6813 consecutive patients was retrospectively reviewed. Two radiologists evaluated CP presence with consensus. Concomitant pancreatic ductal and vascular variations were recorded. The course of the pancreatic duct was classified according to the portal vein as anteportal and retroportal, and pancreas fusion level classified according to splenic vein as suprasplenic, infrasplenic and mixed type...

Accessory rectus muscles have rarely been reported as muscular 'bands' or 'slips' originating from the common tendinous ring (annulus of Zinn) and inserting in atypical location. This group of muscles is innervated by the inferior branch of the oculomotor nerve, lies on lateral side of the optic nerve and inserts in rectus muscles. Since there are only few descriptions of such unusual findings in the medical literature, the anatomical data on accessory rectus muscles is limited. Furthermore, existing reports vary in terms of studied objects (cadavers or living subjects), medical history (absence or presence of ocular movement disorders or eye movement abnormalities) and details of anatomical description...

OBJECTIVE: The aim of this study was to investigate the imaging anatomical characteristics and clinical significance of the ethmomaxillary sinus (EMS). METHODS: The study included a total of 280 ENT Outpatient Department patients with nasal symptoms whose paranasal sinus CT scans were analyzed from January 2012 to December 2016. The anatomical imaging characteristics of EMS were observed. RESULTS: EMS was observed in 23 of 280 patients, with an incidence of 8...

INTRODUCTION: This study was designed to quantify the important anatomical landmarks and the path of the inferior alveolar nerve (IAN) within the human mandibular body and ramus, in particular with reference to the bilateral sagittal split osteotomy (BSSO). MATERIALS AND METHODS: Four hundred and eleven CT scans were studied, 299 of these were involved in determining the position of lingula; and 230 were involved in determining the course of IAN in the mandibular molar region, namely from the mesial of the mandibular first molar to the distal of the mandibular second molar; 118 were involved with both measurements...

PURPOSE: We evaluated the risk of cochlear implantation through the round window membrane in the facial recess through a preoperative analysis of the angle between the facial nerve-round window and the cranial midline using high-resolution temporal bone CT. METHODS: Temporal bone CT films of 176 patients with profound sensorineural hearing loss at our hospital from 2013 to 2015 were reviewed. The preoperative temporal bone CT scans of the patients were retrospectively analysed...

Very rarely, a persistent hypoglossal artery supplies only the posterior inferior cerebellar artery without connection to the basilar artery. Few cases diagnosed by catheter angiography have been reported. We diagnosed a case using magnetic resonance angiography.

PURPOSE: Superimposed three-dimensional (3D)-models obtained from CT-images have been used to evaluate displacement of femoral neck fractures, but this method assumes symmetrical anatomy of normal femurs. The present study aimed to compare the spatial orientation of the left and right proximal femur, thus establishing if 3D models can be used as a reference standard for the evaluation of fracture displacement. METHODS: We generated 3D-CT-models of 20 patients with no skeletal pathology of the proximal femurs...

The mental foramen is an important anatomic landmark located on the buccal aspect of the mandible, typically near the apex of the second premolar. Mental foramina exhibit many anatomical variations, including differences in size, shape, position, and number. The most frequent type of variation in number is the presence of double mental foramen, which has a reported incidence ranging from 1.4 to 12.5%. The incidence of triple mental foramen ranges from 0.7 to 1.2%. The frequency of accessory mental foramina varies among ethnic groups, with a low incidence in white Caucasian populations...

A double left brachiocephalic vein is an uncommon anatomic variation. Among these, a accessory branch with preaortic course is extremely rare. In this case, both branches of the left brachiocephalic vein were anterior to the aortic arch. We describe the computed tomography findings with volume-rendering imaging of this rare anatomic variation.

PURPOSE: Microsurgical reconstruction in a vessel-depleted neck is a challenge due to the lack of reliable vessels in or nearby the host site. The use of the internal thoracic pedicle (ITP) by rib section or sparring is a limited option due to the small length of the pedicle of some flaps. However, in cardiac surgery, the internal thoracic artery (ITA) is widely used for myocardial revascularization, providing a long and versatile pedicle. We aimed at determining precise anatomical bases for the use of the ITP, approached by sternotomy and rerouted in the neck, as recipient vessels for free-flap facial reconstructions...

PURPOSE: There are only two descriptions of posterior longitudinal ligament (PLL) at the lumbar spine level but its morphologic characteristics are different to cervical and thoracic levels. METHOD: Spine explantation (from Th12 to L5) followed by resection of the neural arch and the dural sheath in 13 fresh cadavers was performed. The PLL was isolated from other epidural structures and its width was measured and compared to the vertebral body width at each vertebral levels...
