PERCUTANEOUS RETROGASSERIAN GLYCEROL RHIZOTOMY - CURRENT TECHNIQUE AND RESULTS

Despite the establishment of the vasculoneural compression as a freque nt cause of trigeminal neuralgia, minimally invasive surgical techniqu es to treat medically refractory trigeminal neuralgia are needed in or der to minimize the risks associated with craniotomy. Percutaneous ret ro gasserian glycerol rhizotomy (PRGR) is one of Me alternative surgic al treatments to microvascular decompression. Technical simplicity, le ss chance of trigeminal sensory loss, no need of intraoperative sensor y testing, and no attempted deliberate destruction of the trigeminal n erve are advantages over other percutaneous trigeminal operations.
