Into the cerebral venous system: monitoring an open approach to the cavernous sinus
Background: Epidermoid cysts of the cavernous sinus are rare benign tumours. Their closeness to neurovascular structures carries a certain morbidity when it comes to plan their radical removal, which has been reduced by the development of minimally invasive approaches, such as modern endoscopic techniques. Still, for cases where wider exposure of the workspace is required, the use of intraoperative neurophysiologic monitoring (IONM) gains value. Methods: We present the case of a 19 years old woman with acute photopsia and headache.
