title: Percutaneous retrogasserian glycerol rhizotomy. Current technique and results.
abstract: Despite the establishment of the vasculoneural compression as a frequent cause of trigeminal neuralgia, minimally invasive surgical techniques to treat medically refractory trigeminal neuralgia are needed in order to minimize the risks associated with craniotomy. Percutaneous retro gasserian glycerol rhizotomy (PRGR) is one of the alternative surgical treatments to microvascular decompression. Technical simplicity, less chance of trigeminal sensory loss, no need of intraoperative sensory testing, and no attempted deliberate destruction of the trigeminal nerve are advantages over other percutaneous trigeminal operations.
