Adenoid cystic carcinoma (ACC) is a malignancy of the secretory epithelial cells of the salivary glands and constitutes less than 1% of all head and neck tumors. Metastasis occurs frequently and most commonly affects the lungs at a rate of 35 to 50%. In this case report, we present a rare case of nasopharyngeal ACC with distant metastasis to the li...

... FO shows racial and ethnic differences in shape and size in different populations [15]. In the present study the FO is generally oval (70%) in shape. ...
The importance of the location of the foramen ovale (FO) is particularly evident in external approaches to the skull base. Neighboring structures are of great importance in surgical interventions such as approaches used for trigeminal neuralgia (percutaneous trigeminal rhizotomy), transfacial fine needle aspiration in perineural spread of the tumor, and electroencephalographic analysis for seizures. This study aimed to investigate the morphometry, morphology and anatomical relations of the FO.
Eighty hemicraniums of osteological collection of the Department of Anatomy, Faculty of Medicine, Istanbul University, in Turkey were investigated. In the study, the morphological features of the foramen ovale and their distance to the surrounding anatomical structures were measured.
Oval (70%), almond (18.75%), slit (6.25%), round (5%) shaped foramen ovale were observed. The average length of foramen ovale on the right side was 7.09+1.07mm and 7.06+1.01mm on the left side, while the width was 4.16+0.79mm and 4.15+0.5mm, right and left respectively. The transverse distance of posterolateral edge of foramen ovale to lateral edge of articular tubercle was 33.06+3.25mm, the transverse and vertical distances of foramen ovale to mastoid proccess were, 17.36+3.09mm and 32.40+3.43mm. Finally, measurements of foramen ovale to the carotid canal, the inferior orbital fissure, and the pterygopalatine fossa were 16.70+1.9mm, 27.94+3.2mm and 14.88+1.91mm, respectively. Regional differences in morphometric and morphological analysis of foramen ovale are of clinical and anatomical significance for medical practitioners in neurosurgical procedures, treatment of trigeminal neuralgia, and diagnostic detection of tumors.

... Khan et al. [11] and Khairnar and Bhusari [12] reported the presence of bony growths in the margin of FO but did not describe the bony outgrowths near FS. Sharma et al. [13] observed bony spicules between FO and FS in 6.66% of cases, but they did not clearly describe the location and direction of the bony spicules. In the present study, we observed spinous bony outgrowths in the region of FS in 60% of cases. ...
Objectives: Ossification of the various ligaments at the base of the skull is quite common. Ossified pterygospinous and pterygoalar ligaments have been extensively described in the literature. We observed some bony outgrowths extending from the bar of bone between foramen spinosum (FS) and foramen ovale (FO). The objective of the present study was to report the incidence of these bony outgrowths near the FS. Materials and Methods: Fifty-five dried adult skulls and 20 sphenoid bones were examined for the bony outgrowths (if present) near the FS. Results: Bony outgrowths extended posteriorly from the bar of bone between FO and FS in 60% of cases. These bony outgrowths when long were seen meeting the spine extending from the spine of the sphenoid, forming a complete or incomplete bar of the bone. At times, a thick bony plate joined the bar of bone between FO and FS to the spine of the sphenoid. Conclusions: The bony outgrowths near FS become clinically important in surgeries involving middle meningeal artery. In spite of such implications, these bony outgrowths are neither named nor have they received the due attention in the literature. Detailed studies of these bony outgrowths could be of interest to radiologists, anesthetists, and neurosurgeons.

KEYWORDS Identification, Foramen ovale morphology and morphometery, Gender identification. Anatomical variations of the skull foramens have been of interest for anthropologists, forensic scientists and neuroanatomists. This study aimed to determine the effectiveness of the morphometric measurements foramen ovale to proof its anatomical variations for sex determination in Egyptian dried adult skulls. This study included 25 dry adult human skulls (50 FO); 13 males and 12 females. A digital caliper was used to measure the dimensions of the FO (Length and width); these measurements were taken by two researchers separately. All measurements were conducted bilaterally and repeated three times, the data were statistically analyzed and a comparison between both sides (right and left) FO in skulls of both sexes were done. It was found that there wane differences between the averages meas ±SD length and the width of both sides of FO (left and right) in male skulls with no statistical significance. The same results were found in female skulls. Based on the gender, the linear metric measurements of F.O in skulls of both sexes showed statistical significant difference on the average means ± SD in the length and width of the right and left sides. Various shapes of the F.O were observed in the studied skulls, and the most common shape was the oval shape followed by the almond shape. It can be concluded that, the metric analysis of FO can be useful as a supplement to other skeletal measurements aiming at establishing gender identity of individuals. Also the foramen ovale has a great variation in different countries.
