Yes, a head injury is a common cause of tinnitus. Tinnitus is a condition that causes individuals to perceive sound that is not present in the environment. The damage to the auditory system resulting from head injury can lead to abnormal signals being sent to the brain, which can trigger the perception of tinnitus. The severity and type of head injury can determine the likelihood of developing tinnitus, with more severe injuries such as skull fractures and traumatic brain injuries carrying a higher risk. Tinnitus caused by head injury can be temporary or permanent, and its symptoms can vary from mild to severe.
