Isaac Yang, MD, Neurosurgeon at the University of California Los Angeles Health discusses the role of surgical planning for vestibular schwannoma surgery. He begins by candidly telling the story of his “fifteen years of failures” in the study of the treatment of acoustic neuroma, beginning with hearing and facial nerve function preservation. He then shares the outcomes from several studies to demonstrate these “failures” and what he learned over time about the extent of resection of these types of tumors, specifically in relation to Brainlab Adaptive Hybrid Surgery software. He ends his talk with an in depth discussion about how machine learning and big data will work to inform all types of treatments in the future.
