“…As for sexual dimorphism, the present article did not find any significant difference according to sex, whereas the literature reports that the foramen of Vesalius is more frequent in males [13]. Presence and topographic anatomy of the foramen of Vesalius, and the structures involved, may play an important role in nasopharyngeal tumor spread [13], and the surgical treatment of the middle cranial fossa for the biopsy of lesions of the cavernous sinus [33,37] and transcutaneous intervention for trigeminal neuralgia [38].…”

The sphenoid bone presents several anatomical variations, including accessory foramina, such as the foramen meningo-orbitale, the foramen of Vesalius, the canaliculus innominatus and the palatovaginal canal, which may be involved in tumor invasion or surgery of surrounding structures. Therefore, clinicians and surgeons have to consider these variants when planning surgical interventions of the cranial base. The prevalence of each variant is reported in the published literature, but very little information is available on the possible correlation among different variants. Here, 300 CT scans of patients (equally divided among males and females) were retrospectively assessed to investigate the presence of the foramen meningo-orbitale, the foramen of Vesalius, the canaliculus innominatus and the palatovaginal canal. Possible differences in the prevalence of each accessory foramen according to sex were assessed, as well as possible correlations among different variants through the Chi-square test (p < 0.01). Overall, the prevalence of the foramen meningo-orbitale, the foramen of Vesalius, the canaliculus innominatus and the palatovaginal canal was 30.7%, 67.7%, 14.0% and 35.3%, respectively, without any difference according to sex (p > 0.01). A significant positive correlation was found between the foramen of Vesalius and canaliculus innominatus, both in males and in females (p < 0.01). In detail, subjects with canaliculus innominatus in 85.7–100.0% of cases also showed the foramen of Vesalius, independently from sex and side. The present study provided novel data about the prevalence of four accessory foramina of the sphenoid bone in an Italian population, and a correlation between the foramen of Vesalius and the canaliculus innominatus was found for the first time. As these accessory foramina host neurovascular structures, the results of this study are thus useful for appropriate planning surgical procedures that are tailored to the anatomical configuration of the patient and for improving techniques to avoid accidental injuries in cranial base surgery. Knowledge of the topography, frequencies and the presence/absence of these additional foramina are pivotal for a successful procedure. Clinicians and surgeons may benefit from these novel data for appropriate recognition of the variants, decision-making, pre-operative and treatment planning, improvement of the procedures, screening of patients and prevention of misdiagnosis.

“…The sphenoid emissary foramen (of Vesalius) is a small and inconstant opening that is located medially to the foramen ovale in the roof of the infratemporal fossa [24][25][26][27]. A small emissary vein passes through this foramen.…”

The sphenoid bone, an unpaired, irregular, and pneumatic (air-filled) component of the neurocranium, is a clinically important landmark, particularly in surgery and radiology. This bone is often regarded as one of the most complex bones of the skull. This literature review aims to compile peer-reviewed articles concerning the anatomy of the sphenoid bone while briefly exploring its clinical relevance. The sphenoid bone consists of a centrally positioned body containing the sphenoidal sinus, as well as three pairs of processes projecting from the body, namely the greater wings, lesser wings, and pterygoid processes. The sphenoid is closely associated with five cranial nerves (CNs II, III, IV, V1, V2, and VI) and is adjacent to the pituitary gland. The cavernous sinus, housing the internal carotid artery, lies laterally to the body of the sphenoid. Various neurological conditions, such as injury, inflammation, vascular malformations, aneurysms, and tumors, can either directly impact the sphenoid or occur in close proximity to it. A comprehensive understanding of the anatomy of the sphenoid is indispensable for diagnosing and planning the treatment of these conditions. Therefore, a detailed knowledge of the anatomy of the head, including the sphenoid, is essential in clinical practice. It ensures accurate diagnoses, safe surgical procedures, and effective management of diverse conditions affecting the skull, sinuses, brain, and adjacent structures. Inaccuracies or errors in the diagnosis or treatment of such conditions can lead to adverse patient outcomes, including various complications and delayed management of serious neurological conditions.
