Foramen Of Vesalius

Background: Foramen of vesalius is an inconstant foramen that gives passage to an emissary vein that connects pterygoid venous plexus with cavernous sinus. It lies in the anteromedial side of the foramen ovale. Foramen ovale allows the passage for the mandibular branch of trigeminal nerve, the main site for the trigeminal rhizotomy. The presence and description of anatomical variations about the foramen of Vesalius is important during the surgical procedure on the trigeminal nerve which may injure the emissary vein in the foramen leading to intracranial bleeding. Objectives: The aim of the present study is to report the presence and to enlighten the anatomical variations of foramen vesalius which may serve as a guideline for surgeons. Methods: The study was conducted on 100 dry adult human skulls collected from the department of anatomy at Panimalar medical college hospital & research institute Chennai. The skulls were viewed both extracranially and intracranially to identify the presence of foramen of vesalius. The presence and variation of the foramen was noted and discussed. Result: A total of about 200 sides of 100 skulls were studied. Among them 20% of the skull showed presence of foramen of Vesalius bilaterally, 25% unilaterally and one particular skull showed doubled opening on the left side with the presence of a bony septum. This is a rare variation which was less documented in the literature. Conclusion: The knowledge of variations in foramen of Vesalius may help the surgeons for safer planning and execution of the trigeminal rhizotomy technique.

INTRODUCTION: The foramen ovale is present in sphenoid bone which transmits the mandibular nerve, accessory meningeal artery, emissary vein and the lesser petrosal nerve. This study was conducted on a total 100 si MATERIALS & METHODS: des in 50 dry adult skulls. The shape of foramen will be determined by a visual examination. Margins of foramen were carefully observed for the abnormal bony outgrowths such as sharp bony projections (spine), small blunt bony projection (tubercle), bony plate and bony bar. We obs RESULTS: erved the variations in shape of foramen ovale. We found oval, almond, round, triangular, slit like and irregular shaped in 62%, 20%, 9%, 4%, 3% and 2% foramina ovale respectively. We also observed abnormal bony outgrowths in the foramen ovale like spines, tubercles, bony plate and bony bar. Abnormal bony bar was dividing the foramen ovale in 2 compartments (Anterior and Posterior). The preci CONCLUSIONS: se knowledge of variations of foramen ovale is of valuable contribution for neurosurgeons to development of new and different techniques to approach the middle cranial fossa. In our study we found , 100% tubercles and 80% spines were arising from anterior margin of foramen ovale. These ndings are important for neurosurgeons to approach middle cranial fossa via foramen ovale for neurosurgical and diagnostic procedures like percutaneous biopsy of cavernous sinus tumours, electroencephalographic analysis, microvascular decompression , percutaneous trigeminal rhizotomy and administration of anaesthesia to the mandibular nerve. Surgeons should avoid to go , close to the anterior margin of foramen ovale as spines and tubercles could interrupt the procedures.

Introduction: Computed tomography (CT) has nowadays become the investigation of choice for diagnosis and evaluation of anatomical variations of the nose and paranasal sinuses. Methods: A cross sectional study was conducted in the Department of Radiology of Lumbini Medical College Hospital from June 2019 to May 2020. Total of 130 patients were enrolled for the study. All patients were subjected to Siemens Somatom scope 16 slice CT scan. Each scan was studied for the presence of agger nasi cell, concha bullosa, deviated nasal septum, haller cell, onodi cell, uncinate process variation and type of olfactory fossa. Results: The mean age of patients was 36. 86 ±12.06 years. There were 76 males (58.5%) and 54 females (41.5%) with male: female ratio of 1.4:1 with highest range in age group of 31 to 45 years (46.9%). Anatomical variation between male and female was statistically not significant (p>0.05). The most common anatomical variation noted was nasal septal deviation (73.1%), then agger nasi cell (59.3%), concha bullosa (24.6%), paradoxical medial turbinate (7.7%), onodi cell (6.9%), uncinate process variation (5.4%) and least was haller cell (4.6%). Most of the scans had more than one anatomical variation, which was statistically significant (p<0.05). The most common type of olfactory fossa depth was Keros type II (61.5%). Conclusion: Computed tomography of the paranasal sinus has improved the visualization of anatomical variation hence radiologist must pay close attention to variants.

Background: The thinnest portion of the medial wall of the orbit is Lamina orbitalis ossis ethmoidalis which separates the ethmoidal sinuses from the orbit. Congenital bony malformation of orbit and anatomical variation of ethmoidal sinuses are important in terms of the risk of complication development during endoscopic sinus surgery and to understanding the pathophysiology and spread of sinus disease.Materials and Methods: Accordingly the present study was designed to fi nd out the congenital malformation of medial wall of the orbit in relation to lamina orbitalis ossis ethmoidalis. The study was carried out using 100 dried adult human skulls and twenty six human cadavers irrespective of sex were obtained from the Department of Anatomy - Mayo Institute of Medical Sciences-Barabanki, Department of Anatomy - Melaka Manipal Medical College - Manipal and Department of Anatomy - KMCT Medical College, Manassery - Calicut.Results: In three skulls (2.380%) we noted unilateral unusual hole at the junction of medial wall and roof of orbit with dimensions of 2.3 cm long and 1 cm height in two skulls and another unusual vertical hole at the anterior part of medial wall and roof of orbit with dimensions of 2 cm height and 1 cm width. We also noted few ethmoidal cells extended in to the orbital plate and fovea ethmoidalis of the frontal bone.Conclusion: Congenital defective formation of bony orbit and variable anatomy of paranasal sinuses noted in this study is may be due to the defective formation of Lamina orbitalis ossis ethmoidalis from the lateral part of the nasal capsule near the fronto ethmoidal suture such comprehensive knowledge is necessary to understand the various disorders of this region and to avoid complications during surgical procedures involving this area.DOI: http://dx.doi.org/10.3126/ajms.v6i2.10534Asian Journal of Medical Sciences Vol.6(2) 2015 91-94

Introduction. The foramen Vesalius is a variable foramen located at the skull base, anteromedial to the foramen ovale behind and lateral to the foramen rotundum. This foramen is also known as emissary sphenoidal foramen. The aim of the research was to determine the anatomical characteristics of the foramen Vesalius in adult human skulls and foramina classification according to their type, shape, and sex distribution. Material and Methods. The study included 26 dry adult human skulls of both sexes from the collection of the Depart?ment of Anatomy, Faculty of Medicine of the University of Novi Sad. The skulls were macroscopically analyzed according to the presence or absence of the foramen Vesalius. Results. The foramen Vesalius was found in 16 skulls (61.54%) and it was absent in 10 skulls (38.46%). The incidence of bilateral and unilateral foramen Vesalius was 87.5% (14 skulls) and 12.5% (2 skulls), respectively. The foramen Vesalius was found in 10 male skulls (62.5%) and in 6 female skulls (37.5%). Conclusion. Based on the morphological analysis of the skulls, the study showed that the foramen of Vesalius can be unilateral or bilateral. The bilateral foramen was more common and it was usually round and symmetrical. In regard to the sex prevalence, the foramen was more prevalent in male than in female skulls. The results of the study showed that foramen Vesalius is not an uncommon anatomical variation, and its presence and morphological appearance are important information for physicians in various fields.

Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

Background: This study is cross-sectional, observational and comparative study, at Index Medical College, Hospital & Research Centre, Indore, Madhya Pradesh from July 2017 to July 2019 with sample size 100 placentae. Method: The placenta received was evaluated blinded of maternal pregnancy outcome. The pattern of morphology was evaluated both qualitatively (type of lesion) and quantitatively (number of lesions). Result: In Present study 79% of the deliveries were term deliveries and 21% were preterm deliveries. On placental macroscopy, placenta weight was significantly low among the neonates of preterm deliveries (370.00±60.49) as compared to term deliveries (440.89±55.22). Preterm placenta had higher number of abnormal placental lesion compared to term pregnancies. Conclusion: The uteroplacental insufficiency defined as placental infarct, fibrosis of chorionic villi, thickening of blood vessels, and poor vascularity of chorionic villi. Placental histopathological lesions are strongly associated with maternal under perfusion and uteroplacental insufficiency. These are the reasons for preterm birth. Thus, knowledge of the etiological factor can be use to reduce maternal and neonatal morbidity and mortility. Keywords: Placenta, Term & Preterm.
