Paralysis of any of the twelve cranial nerves is referred to as cranial nerve palsies. Symptoms vary according to what nerve has been affected. Some common cranial nerve palsies are: oculomotor nerve palsy, facial nerve palsy, abducens nerve palsy, trochlear nerve palsy, glossopharyngeal and trigeminal neuralgia.
- A cranial nerve examination is useful in identifying a cranial nerve palsy.
- Oculomotor, abducens and trochlear nerve palsies affect directional eye movement.
- Trigeminal and facial nerve palsies affect facial sensation and expression.
- Glossopharyngeal palsies affect swallowing and speech.
