Microscopic and Endoscopic Skull Base Approaches Hands-On Cadaver Course at 30: Historical Vignette.

Laboratory-based cadaveric training is essential for the development and refinement of neurosurgical technical skills in the operating room and has become an integral training component around the world. Postresidency fellowship-the first pillar of skull base surgery training-includes both hands-on clinical care and surgery supervised by an experienced skull base surgeon. Time is spent in a skull base laboratory practicing approaches and developing anatomic mastery. The second pillar includes formal skull-base courses-institutional dissection laboratories provide continuous anatomic and surgical education while complementary annual or semiannual cadaver courses gather recognized experts to share their knowledge and experience in an essential 2- to 3-day setting. In this paper, we present the history of the longest running annual skull-base cadaver microsurgical course, which was started by Dr. Ossama Al-Mefty: Annual Surgical Approaches to the Skull Base Course. At the Microscopic and Endoscopic Hands-on Cadaver Workshop, held in St. Louis, Missouri, we celebrated its 30th anniversary in April 2019. We also present the impact this course has had on neurosurgery and skull base surgery and on the professional and scientific developments of its participants in particular.
