There are three well-established percutaneous techniques such as radiofrequency rhizotomy, glycerol rhizotomy and balloon compression aimed at the gasserian ganglion or the trigeminal nerve roots in treating trigeminal neuralgia, but no consensus as to which is best. Each method has its relative advantages and disadvantages. All of the procedures share the result of treatments with the risk of complications related to needle placement and lesion making method. They aim to obtain the greatest chance of long-term pain relief with fewest complications. The procedure with the needle to the foramen ovale is done by the help of cutaneous landmarks and radiological guidance. The neurosurgeon must exercise their understanding of the anatomy and radiology. In treating trigeminal neuralgia in an older or frail patient, the percutaneous procedures yield a highly effective results with acceptable morbidity. And they are relatively simple, safe, and cost-effective compared to microvascular decompression. Author describe percutaneous techniques for trigeminal neuralgia including the penetration of foramen ovale, procedures, outcomes, and indications with references.
Key Words: Trigeminal neuralgia, Radiofrequency rhizotomy, Glycerol rhizotomy, Balloon compression.
