Fracture of the basilar skull This is the most severe form of skull fracture, including a break in the bone near the base of the skull. Bruises around the eyes and behind the ear are common in patients with this type of fracture. Patients may have vomiting, dizziness, loss of consciousness, and seizure activity immediately after the injury or later if not treated properly. The brain must be protected at all times during treatment of these injuries, which usually requires surgery to repair the damage. Bruising around the eye and behind the ear is common in patients with this type of fracture. Concussion A concussion is a traumatic brain injury that causes symptoms such as headache, confusion, memory problems, visual disturbances, and dizziness. These symptoms will resolve themselves, but it is important to receive medical attention if you show signs of multiple concussions. Concussion-related symptoms can be caused by any object that impacts the head, including fists, feet, bats, baseballs, basketballs, hockey pucks, shovels, and knives. Concussions can be difficult to diagnose because there are no specific tests for them.
