These are the veins that penetrate the bones of the skull, forming a connecting network between the veins on the outer surface of the skull and the dural sinuses inside. These veins also serve as a potential pathway for infections to spread from outside the skull to the brain. One particularly crucial vein is located near the base of the nose. Consequently, if an infection, such as a boil, develops on the cheeks, there is a heightened risk that bacteria may travel through this vein into the skull, potentially causing severe damage. This is why the front of the cheeks is considered a high-risk area, and infections in this region are treated with utmost care. Despite the patient’s objections, it is common practice to hospitalize them and ensure they remain quiet and still until the infection is under control.
