S04.9: Injury of unspecified cranial 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.
Injuring a cranial nerve can cause a range of symptoms. You may have problems with your sight, hearing or sense of smell. You may also no longer be able to feel anything in certain parts of your face. You may no longer be able to move certain muscles properly.
