Potential future treatments

- Unilateral lancinating facial pains
- Severe, very brief but repetitive pain
- It causes the patient to flinch as it happens with motor tic.

- Antispasmodic agents. such as baclofen
- Botox injections
Following are the Surgical options for trigeminal neuralgia:
- Microvascular decompression
- Brain stereotactic radiosurgery (Gamma knife)
- Glycerol injection
- Balloon compression
- Radiofrequency thermal lesioning
