Battle sign refers to bruising located where?

• A. Bruising behind the ear
• B. Bruising on the nose
• C. Bruising on the cheek
• D. Bruising under the chin

Answer: (A)

Battle sign is bruising located behind the ear, over the mastoid process. This finding points to a basilar skull fracture, a serious injury that can accompany head trauma. It often appears hours to a day after the injury as blood tracks into the tissue behind the ear. Recognizing it prompts urgent imaging to assess the fracture and careful monitoring for other basilar skull fracture signs, such as clear drainage from the ear or nose or changes in consciousness. In care, anticipate imaging like a CT scan, protect the airway and neurologic status, and avoid nasal instrumentation if a basal fracture is suspected, since nasal tubes or suction can worsen injury.
