Three operative strategies now prevail: percutaneous procedures, gamma knife radiosurgery (GKRS), and microvascular decompression (MVD). Ninety percent of patients are pain-free immediately or soon after any of the operations, though relief lasts far longer with MVD. Pain-free intervals last on average 1.5–2 years after two of the percutaneous procedures (percutaneous retrogasserian glycerol rhizotomy [PRGR] and percutaneous balloon microcompression [PBM]), 3–4 years after GKRS, 4–5 years after another percutaneous procedure (radiofrequency trigeminal gangliolysis),  and 10–12 years after MVD.
