Glossary

Percutaneous destructive neurosurgical techniques Neurosurgical procedures that require needle insertion through the skin of the cheek, and that cause partial destruction (ablation) of the trigeminal nerve by selectively targeting damage to the small unmyelinated and small myelinated pain fibres of the trigeminal nerve, while ideally sparing the rest of the nerve fibres (e.g., radiofrequency thermocoagulation, glycerol rhizolysis, and balloon compression). Also known as percutaneous ablative surgical procedures.
