To treat trigeminal neuralgia, your doctor usually will prescribe medications to lessen or block the pain signals sent to your brain.
- Antispasmodic agents.
- Botox injections.
Cases not responding to medical management and lifestyle modification ,are advised to go for:-
Radiofrequency thermal lesioning. This procedure selectively destroys nerve fibers associated with pain. While you’re sedated, your surgeon inserts a hollow needle through your face and guides it to a part of the trigeminal nerve that goes through an opening at the base of your skull.
Once the needle is positioned, your surgeon will briefly wake you from sedation. Your surgeon inserts an electrode through the needle and sends a mild electrical current through the tip of the electrode. You’ll be asked to indicate when and where you feel tingling.
When your neurosurgeon locates the part of the nerve involved in your pain, you’re returned to sedation. Then the electrode is heated until it damages the nerve fibers, creating an area of injury (lesion). If your pain isn’t eliminated, your doctor may create additional lesions.
Radiofrequency thermal lesioning usually results in some temporary facial numbness after the procedure. Pain may return after three to four years.
A few resistant cases may need to consider surgery.
Brain stereotactic radiosurgery (Gamma knife)
