Which phrase describes an open traumatic brain injury?

• A. An injury in which the skull is fractured
• B. An injury with no skull fracture
• C. Inward indentation of the skull
• D. Hematoma without skull fracture

Answer: (D)

Open traumatic brain injury means there is a breach in the skull that creates an opening to the outside, often with exposure of brain tissue. This typically occurs when the skull is fractured and a wound communicates with the brain, allowing external contamination and a direct pathway to the brain. Because of that, the description that best fits an open injury is the one indicating a skull fracture, since a fracture can create the opening needed for the brain to be exposed. A hematoma without skull fracture describes a closed injury, where the skull remains intact and there’s no external communication. An inward indentation points to a depressed fracture, which may be open or closed depending on whether the dura is breached and brain tissue is exposed, so it isn’t as definitive for open injury.
