Minimally invasive mastery: transorbital endoscopic excision of the paramedian epidermoid.

Endoscopic minimally invasive skull base surgery using the transorbital neuroendoscopic technique for cavernous sinus epidermoid serves as a pivotal link to open transcranial surgeries. This method involves a minimally invasive transorbital approach, including lateral orbitotomy and drilling the greater sphenoid wing, followed by cutting the orbitomeningeal band, peeling the dura mater, and exposing the tumor. This approach is technically demanding and requires thorough knowledge of anatomy and familiarity with endoscopic instruments. The favorable clinical, cosmetic, and radiological outcomes underscore the effectiveness of this technique, highlighting the role of endoscopy in minimally invasive skull base paramedian pathologies.
