“…But, our finding of SEF looks more or less concomitant to the data of previous 27 studies in the Japanese (21.75%) and the Turkish (28.1%, 28 81/317) popula on. It has been found even higher in other 25,[29][30][31] popula ons ranging from 40 -80% (Table 3), sugges ng it as a common varia on. However, its existence and considera on may help for the safer percutaneous approach to the middle cranial fossa through the foramen ovale, which could be mistaken with the SEF.…”

Introduction: Atlanto-occipitalization(AOZ) is one of the congenital anomalies related to craniovertebral synostosis. The clear understanding of its anatomical features and cranial foraminal variants plays a critical role in finding the possible coping mechanism with its pathogenesis such as segmental instability or neurologic deficits. Objective: This study aimed to investigate the incidence of occipitalization of Atlas and related variant foramina, as the baseline awareness of these conditions among the Nepalese population is yet to be documented. Methodology: A retrospective study was performed for the total 86 dry skulls available in the department of Anatomy in Katmandu University of Medical Sciences, Institute of Medical Science, and B.P. Koirala Institute of Health Sciences. The skulls were examined thoroughly to evidence the occurrence of cranio-vertebral variations. Result: Out of 86 human adult skulls, 2 cases (2.32 %) were found with partial AOZ presenting posterior spina bifida close to the midline. Sphenoidal emissary foramen (SEF) was also observed in 17 skulls (19.76 %), an additional foramen lying anteromedial to the foramen ovale. Moreover, one of the skulls (1.16 %) was found with the presence of pterygospinous bar creating an additional foramen ‘foramen of Civinini’ in the lateral pterygoid plate of the sphenoid bone. Conclusion: The incidence of AOZ and pterygospinous bar seems to be quite low as compared to the cases of SEF. However, the knowledge of such variations and the presence of additional foramina carry great significance for orthopedists and neurosurgeons to have prognostic implications and an accurate surgical approach.

“…In the literature, although the morphology of the FO is mostly described as oval, it is quite diverse in terms of morphological and morphometric features compared to other foramina (Khan). In addition to its oval shape, "almond", "Dshape", elongated oval", "oval", "round", semicircular, "slit", with irregular borders, bordered by bony spurs, spines, and tubercles are also used to describe it, and it has also been expressed in very different terms, such as "pear" and "truly oval" [3].…”

Background/Aim: The foramen ovale (FO) is very important in neurosurgical approaches; however, studies and developments in the literature report that no definite consensus about the cannulation of the FO is available. Therefore, more morphometric information concerning the FO is needed in addition to the previously defined morphological and morphometric features. The aim of this study was to compare the features of the foramen ovale stated in the literature and to analyze the topographic relationship between the FO and the anatomical structures around it to determine its precise location. Methods: The study included 70 sides from 35 dry skulls of unknown age and gender. Skulls with any deformity or pathology that would affect the measurements were not included in the study. All skulls were placed in the horizontal plane with the external occipital protuberance facing posteriorly, the piriform aperture facing anteriorly, and the skull base pointing upwards at a 90° angle after which it was photographed vertically with the length scale. A Nikon D5300 Digital Camera was used for the photography, and digital image processing software (Image J) was used for foramen ovale measurements. In addition, the shape of the foramen ovale was classified as oval, almond, D-shaped, slit-shaped, round, and irregular. SPSS 21.0 was used for the statistical analysis. Results: The mean anteroposterior diameter length of the FO was 6.144 mm, and the transverse diameter length was 2.885 mm. When the distribution of the shape of the FO was examined, oval and almond shapes were most common shapes (34.29%). In addition, round (12.85%), D-shaped (10%), and slit-shaped (8.57%) were obtained. According to Pearson’s correlation analysis, the highest correlation was between the distance from the carotid canal to the foramen ovale and the shortest distance from the foramen ovale to the midline (FO-CC and the FO-ML, respectively; r = 0.427). Conclusion: The morphology of the FO is important in terms of surgical and interventional approaches. In the literature, no significant differences between the right and left sides for the foramen ovale were found in contrast to our study. When the FO shape percentages were examined in most previous studies, it was seen that most of them were oval. In this study, the ratios of oval and almond shapes were the same. Morphometric measurements can give different results in every race due to the structure of the bones, which may vary according to the population. We think that presenting data on the Turkish population in this study will set an example for conducting future studies.

“…Esta comunicación pudiese ser motivo de complicaciones clínicas, tales como el paso de procesos infecciosos desde exocráneo al seno cavernoso, asociado a complicaciones como trombosis séptica de seno cavernoso, meningitis bacteriana, abscesos e infartos cerebrovasculares (Freire et al 2013). También se han reportado complicaciones clínicas asociadas a técnicas neuroquirúrgicas de tratamiento de neuralgia del Nervio trigémino, existiendo terapias que involucran abordajes quirúrgicos que utilizan al AO como vía de acceso al ganglio trigeminal (Ozer y Govsa, 2014), pudiendo la proximidad y presencia del FV al FO provocar complicaciones potencialmente graves (Rossi et al 2010;Natsis et al 2018). Los diversos estudios realizados para investigar morfología de estructuras anatómicas se han centrado principalmente en el estudio de osamentas, mediante visión y medición directa (Ukoha et al 2018); en algunos casos los estudios se complementaron con estudio fotográfico y medición computacional para obtener medidas más precisas (Chaisuksunt et al 2012).…”

Introducción: El Agujero Venoso es un reparo anatómico inconstante localizado en la base de cráneo, específicamente en el ala mayor del Esfenoides, anteromedial al Agujero Oval. Este permite el paso de una vena emisaria esfenoidal, la cual conecta al plexo pterigoideo con el seno cavernoso. Su presencia se ha relacionado con complicaciones clínicas en procedimientos neuroquirúrgicos y es una potencial vía de acceso de procesos infecciosos a la cavidad craneal. Objetivo: Determinar la prevalencia y las características morfológicas más prevalentes del Agujero venoso analizadas mediante tomografía computarizada de haz cónico (CBCT). Material y método: Se estudiaron 126 CBCT de adultos chilenos disponibles en el Departamento de Anatomía de la Universidad Finis Terrae, en un análisis estadístico donde se observaron las variaciones en la incidencia, morfología, permeabilidad y distancia a otras estructuras anatómicas: Agujero Espinoso, Agujero Oval y línea media. Resultados: Se observó la presencia del Agujero Venoso en un 19% de la población. 87.5% se encontró unilateralmente y 12.5% bilateralmente. El 48,1% fueron redondeados y el 51,9% irregulares. El diámetro promedio fue de 2.2 mm, con un 100% de ellos permeables. Las distancias promedio entre el Agujero Venoso y el Agujero Oval, el Agujero espinoso y la línea media fueron 1.72 mm, 10.14 mm y 19.7 mm. respectivamente. Conclusiones: El Agujero Venoso se presentó en el 19% del total, en forma ovalada o irregular, anteromedial al Agujero Oval, presentándose principalmente de manera unilateral. Dichas características anatómicas de este agujero deben considerarse durante las intervenciones neuroquirúrgicas en la fosa craneal media.
