[Advances in Intraoperative Neurophysiological Monitoring Techniques in Transnasal Endoscopic Skull Base Surgery]

Abstract

Transnasal endoscopic skull base surgery has been increasing in volume in recent years and its indications are constantly expanding. The potential occurrence of intraoperative and postoperative neurovascular complications deserves special attention from neurosurgeons. Multimodal intraoperative neurophysiological monitoring technology allows neurosurgeons to monitor cerebral perfusion and the functional status of the associated cranial nerves in real time, thereby enabling surgeons to make prompt adjustments in surgical procedures and strategies and reduce the risks of postoperative neurological complications in patients. Based on available literature, we reviewed how appropriate monitoring strategies were optimized for different key components of transnasal endoscopic skull base procedures, intending to provide reference for clinicians.
