S04.3: Injury of trigeminal nerve
Various nerves run from the brain to the sensory organs in the head, and to organs in the body. These nerves are called cranial nerves. These nerves are important in seeing, tasting or hearing, for example. But the cranial nerves also control important functions in the body, such as in the lungs and heart.
You have injured your trigeminal nerve. The trigeminal nerve is on each side of the body, starting in your brain and coursing down the face to the masseter muscles (chewing muscles). The trigeminal nerve enables us to feel sensations on the skin of the face and on the tongue. These sensations include, for example, touch, heat and pain. The trigeminal nerve also runs to the chewing muscles so that we can chew. If the trigeminal nerve is injured you may no longer be able to feel anything in certain areas of the face. You may also no longer be able to feel anything with the front of your tongue. You may also have pain in certain parts of your face. You may not be able to chew properly.
