Improved Intraoperative Visualization Enhances Resection of Skull Base Tumors


Orin Bloch, MD, discusses why image guided surgery is preferable over “look and feel” or navigating from MRI alone during skull base tumor resection. Dr. Bloch uses two cases to demonstrate how visualization benefits minimalist (keyhole cranio-orbital) and maximalist (hyperostosing meningioma) approaches. He explains that visualization during surgery means using image guided navigation to accomplish several goals: Localizing lesions and orienting in the case of small openings as well as anatomy that’s been obscured by tumor, choosing the correct approach both before and during surgery, assessing progress intraoperatively, and minimizing exposure, pain for the patient, as well as surgical time. Dr. Bloch also discusses the importance of intraoperative imaging as well as Adaptive Hybrid Surgery to assess the extent of resection. Finally, he covers the importance of automated registration through intraoperative imaging to achieve accurate results: “The quality of navigation is only as good as the registration”.

Thank you. So actually having seen on an earlier version of the program that I was following Dr. Bederson and knowing, you know, all of the fantastic work that's being done at Mount Sinai with augmented reality and heads of visual display and so forth, I actually decided to build off of that guessing that this is what your talk would be and kind of take it to the next level and show you, you know, kind of simplified a little bit, what we can do with the technologies that we have in the operating room now. So I think...
