32 How to choose the right procedure?
Trigeminal neuralgia – MVD? Multiple sclerosis – RF PTG? Elderly patients – SRS? Anesthesia dolorosa – MCS? Atypical facial pain – no surgery?

33 Rationale for algorithm
Facilitates decision making Aimed at maximal improvement / minimal side effects Individually tailored approach Standardization Eliminates uncertainty Patient and physician education

48 Facial pain treatment algorithm

49 Current Algorithm of Facial Pain Treatment
~ 100 new patients with facial pain/year ~ 65% - trigeminal neuralgia ~35% - typical idiopathic TN ~15% - atypical idiopathic TN ~15% - secondary TN (MS, neoplasms, etc.) ~ 15% - trigeminal neuropathic pain ~ 5% - other cranial neuralgias / syndromes ~ 15% - atypical facial pain

50 Current Algorithm of Facial Pain Treatment
~ 70 surgeries for facial pain /year ~20-30 microvascular decompressions ~15-25 percutaneous RF gangliolysis ~2-3 balloon compressions ~5-15 GK radiosurgery ~1-3 trigeminal peripheral nerve stimulation ~0-1 motor cortex stimulation

51 Current Algorithm of Facial Pain Treatment
96% pain relief (at the time of discharge) 23% overall recurrence rate ~15% need another procedure 98% patient satisfaction

52 Current Algorithm of Facial Pain Treatment
The proposed treatment algorithm for intractable facial pain that includes open and percutaneous procedures, radiosurgery and neuromodulation, appears to be effective for patients with a wide variety of painful conditions and may be recommended for use in other institutions.
