Core tip: Neuronavigation-assisted neuroendoscopic surgery has been remarkably advancing. Furthermore high definition video recording system becomes its basic visualization system to facilitate the differentiation between normal tissue and abnormal tissue of hypothalamic hamartomas. Neuroendoscopic disconnection has been suggested to reduce the Gelastic seizure by the isolation of hypothalamic hamartomas (HHs) from surrounding structures. We are getting more powerful tools for performing sophisticated endoscopic disconnection surgery. Neuroendoscopic disconnection surgery used to be an optional surgery, but it becomes the first choice of surgery for HH with Gelastic seizure.
