Open head injuries occur when an object penetrates the skull, causing a break in the protective barrier of the skull and exposing the brain to the external environment. These injuries can result from accidents, falls, or violent incidents, and they often lead to significant damage to brain tissue and surrounding structures. Symptoms of open head injuries may include bleeding, swelling, and loss of consciousness. Due to the risk of infection and severe complications, immediate medical attention is crucial. Treatment often involves surgery to repair the skull and address any damage to the brain or other affected areas.
