The foramen ovale: A microsurgical anatomic study. StatPearls Publishing; Treasure Island (FL): Feb 15, 2025. For these networks to traverse and communicate with the entire body, the foramina must provide passage through the skull. This could revolutionize the treatment of conditions like brain tumors or neurodegenerative diseases. While the Central Canal of the Brain: Anatomy, Function, and Clinical Significance is the main highway for CSF, the foramen ovale acts like a local side street, allowing for finer adjustments in CSF flow.

Through the foramen ovale, surgeons can access the trigeminal ganglion and selectively destroy pain fibers, providing relief to patients suffering from this debilitating condition. [PubMed: 30385045]

The human version tends to be more consistently oval-shaped and centrally positioned compared to many other mammals. Its primary function is to serve as a conduit for the mandibular branch of the trigeminal nerve, the largest cranial nerve in our body. It encompasses emissary veins that drain the nasal cavity of blood and reroutes it to the superior sagittal vein.
