More otolaryngologists are being approached by both patients and colleagues in collaborative departments to help them with endoscopic skull base surgery. Participants will be refreshed on complex skull base anatomy, then see examples of not only basic sellar approaches, but then also expanded, complex skull base procedures which reinforce the anatomic lessons learned at the beginning. Although a rhinology fellowship is the best method to gain the expertise needed for such surgeries, this expert lecture can give you the necessary knowledge of anatomy, surgical corridors, tools and techniques to begin your endoscopic skull base practice.
