Cranial nerve (CN) injuries may arise as a result of trauma or disease. Any of the 12 cranial nerves may be affected either alone or in combination.

This session will look at CN I to VI in turn, and review:

• The structures each nerve supplies
• Signs of injury to the cranial nerve
• How to test the cranial nerve
• Traumatic causes of injury
• Medical causes of injury
• Situations in which cranial nerves are commonly injured together
