Abstract:Observations in this study tender new anatomic parameters regarding SEF incidence, characteristics, and distances to proximate anatomic structures. Knowledge related to SEF variations will be helpful for neurosurgeons and radiologist.
“…Unlike mentioned studies, Bayrak et al [16] state that the mean diameter on the right side is 2.66 mm, and 2.82 on the left side, which is bigger than the results of our study. To best of our knowledge, there are no possible explanations for the difference in the diameter of the FV in different authors in contemporary literature.…”

“…In their research, Shinohara et al [12] and Shaik et al [13] state that the foramen representation is 33.75% and 36%, respectively, which is less than the results of our study. According to most authors, the incidence of the FV is lower (Table 4) [3,[12][13][14][15][16][17][18][19][20]. There is a significant discrepancy in the incidence of the FV between various authors.…”
Introduction/Objective. The foramen of Vesalius (FV) is a variable foramen
located at the base of the skull, anteromedial to the foramen ovale, and
lateral to the foramen rotundum. Through this foramen, passes one of the
emissary veins, which establishes communication between the cavernous sinus
and the pterygoid plexus. The aim of the study was to determine the incidence
of this foramen in adults depending on gender, along with the number of
foramina, distributions relative to the side of the skull and diameter of the
foramen. Methods. A material used in the study were digital CT scans of adult
paranasal cavities from the archives of the Radiology Center, archived in the
PACS software system. We analyzed axial CT sections of 1 mm thickness. The
research included 500 subjects (250 males and 250 females). Results. The
foramen of Vesalius was present in 67.6% of respondents. In 50.9% cases, the
foramen was bilateral and in 49.1% it was unilateral. The average oblique
diameter of the foramen in men was 1.75 ? 0.59 mm and in women 1.56 ? 0.48
mm. In 22 subjects (6.51%) the foramina were doubled, and 2 (0.60%) were
tripled. Conclusion. There was no statistically significant difference in the
incidence of the foramen of Vesalius concerning gender. The mean diameter of
the foramen was statistically higher in males. The presence of this foramen
is important for neurosurgeons because, during the percutaneous trigeminal
rhizotomy, the needle can pass through this foramen, injure the surrounding
blood vessels, and lead to intracranial hemorrhage.

“…Estos hallazgos no concuerdan con lo observado en nuestro trabajo, donde no se evidenció ningún foramen con diámetro menor a 1 mm. Lazarus et al (2015) afirmó que un diámetro hasta 0,5 mm permitiría realizar técnicas quirúrgicas percutáneas de forma segura; sin embargo, nuestro estudio arrojó que la media de diámetro de los forámenes analizados fue de 2,27mm, muy similar a los resultados obtenidos por do Nascimento et al (2018) y Bayrak et al (2018) en este último las medias de los diámetros fluctuaron entre 2,68 mm y 2,88 mm siendo esto muy superior a otros estudios como Chaisuksunt et al (2012) y Shinohara et al (2010), quienes informaron diámetros de este foramen entre 0,65 mm y 1,93 mm. Con respecto a la forma 48,1% eran redondeados, mientras que 51,9% fueron irregulares.…”

“…1). Su origen se relacionaría con el FO, ya que se formaría producto de la osificación de una espícula ósea que atravesaría al FO dando como resultado dos forámenes con características anatómicas propias, siendo uno de los motivos de la estrecha relación de ambos reparos anatómicos (Bayrak 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). Otro método de utilidad, pero menos usado, es el método imagenológico tridimensional; donde se han reportado análisis de forámenes de base craneal mediante tomografía axial computarizada (Gingsberg et al 1994;Ginat et al 2013 (Bayrak et al 2018;Görürgöz y Paksoy, 2020) siendo una alternativa ventajosa en el análisis del FV. El objetivo de este estudio es determinar la presencia y las características morfológicas más frecuentes del FV analizados en una población chilena mediante estudios imagenológicos tridimensionales.…”
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.
