The treatment of a fractured skull depends on the type and severity of the fracture. In some cases, such as a small linear fracture, they may be able to heal on its own without the need for surgery. More severe fractures, such as depressed fractures, will usually require immediate surgery in order to protect the brain. Doctors may be able to salvage the bone, or they may have to fit the patient with a metal plate in order to keep their brain protected.
