This intimate 3-day dissection-centered course forces on complex skull base approaches including the fronto-orbitozygomatic, pericavernous, middle fossa anterior petrosectomy, translabyrinthine, far lateral. All material is presented in an immersive 3D format in Weill Cornell’s state-of-the-art Neurosurgical Innovations and Training Center. Participating surgeons work at 3-D interactive cadaver workstations, where they watch cadaveric dissections and review surgical anatomy—all in 3D—before and during their own dissection. The combination of the 3-D virtual reality environment and the cadaveric hands-on dissection affords surgeons excellent preoperative training and rehearsal of current, complex approaches in cranial base surgery.
