Trigeminal neuralgia (TN) is a facial pain disorder that can be a source of significant disability. Percutaneous balloon compression (PBC) has low cost, high efficacy, and minimal invasiveness. Complications can occur due to the balloon inflation or the needle placement itself. In this paper, we describe for the first time the clinical use of robotic-assistance to perform a PBC for TN, presenting our experience in two patients. The stereotactic planning targeted the foramen ovale (FO) establishing a safe and seamless needle trajectory. This yielded a streamlined, single pass needle placement and eliminated the need to "search" for the FO. There were no immediate complications and post-operatively both patients improved their symptoms. Robotic assistance is potentially a useful tool to reduce needle placement related complications, radiation exposure and PBC learning curve.
