Abstract
Background: Epilepsy is a prevalent chronic neurological disease affecting millions. Many patients respond to medical therapies, but a third of patients does not and potentially requires neurosurgical procedures. These can be used to localize the onset of seizures and subsequently treat patients. Robotic technologies have emerged over the last decades to increase the efficacy and safety of epilepsy surgery. We therefore wanted to describe the role that robotics in epilepsy surgery have taken since their introduction more than 30 years ago. Summary: Robotic assistance in epilepsy surgery has evolved for more than 30 years. Its earliest use in stereotactic EEG (SEEG) implantations has now also become its most widely used application. Multiple studies have demonstrated that robotic guidance increases the accuracy while also making the implantation of electrodes faster. Beyond diagnostics, robotics have also gained widespread acceptance in ablative neurosurgical procedures where robotic systems improve the placement and can even aid in the finetuning of laser fibers for laser interstitial thermotherapy (LITT). Additionally, robotics have been employed in the placement of electrodes for intracranial neuromodulation therapies in epilepsy such as deep brain stimulation (DBS) and responsive neurostimulation (RNS). Ongoing innovations are further expanding the uses of robotic technologies in epilepsy surgery from aiding in endoscopic procedures to automated craniotomies. Key Messages: Robotics in epilepsy surgery have come a long way and have already taken a central role in procedure intended for diagnostic and therapeutic purposes. This narrative review details its many benefits and provides an outlook for future developments.
