Ask about glycerol injection. Glycerol injection is used to treat trigeminal neuralgia that particularly affects the third and lowest branch of the trigeminal nerve.
- During this outpatient procedure, a thin needle is inserted through the cheek into the base of the skull and near the 3rd division of the trigeminal nerve.
- Once the glycerol is injected, it damages the trigeminal nerve, resulting in pain relief.
- This procedure usually results in about 1 to 2 years of pain relief.
