Trigeminal neuralgia (TGN) is a debilitating pain syndrome. Various theories have been postulated to explain the origin of TGN [1–3]. The first-line of management includes medications such as carbamazepine, oxycarbamazepine, phenytoin, gabapentin, pregabalin, and baclofen. It is quite common that the patients become resistant to these drugs over period of time. That is the reason why many patients would require some other management strategies. The alternative treatment modalities include different surgical options which can be divided as ablative or non-ablative procedures. Microvascular decompression (MVD) is the only non-ablative surgical procedure available. The ablative procedures lead to pain relief by lesioning of the trigeminal nerve; and include percutaneous techniques such as balloon compression, retrogasserian glycerol rhizotomy, and radiofrequency lesioning. Gamma Knife radiosurgery (GKRS) is a minimal invasive technique used to control TGN.
