Using perioperative computed tomography (CT) guidance, ablation of the descending spinal trigeminal nucleus and trigeminal tract can be performed precisely to mitigate damage to surrounding structures. These patients are subsequently followed with postoperative imaging and clinical visits to assess long\u2010term pain relief.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this report, we present a series of four patients with trigeminal neuralgia who were had refractory disease after prior medical and surgical interventions. These patients underwent CT\u2010guided percutaneous trigeminal tractotomy for pain relief. The patients underwent postoperative MRI and were followed for up to 6 months for long\u2010term clinical outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For intraoperative CT, we find that preprocedure lumbar contrast injection enables better visualization of the cord during placement of the ablation probe. On postoperative imaging, we find that all four patients have hyperintense lesions on T2\u2010weighted MRI that correspond with the location of the trigeminal nucleus and tract.
