There are up to 21 million image-guided surgeries in the United States and 118 million image-guided surgeries performed worldwide each year. Image-guided surgeries include laparoscopic, robot-assisted, or endoscopic, which are modalities commonly used across nearly all surgical specialties. Thus far, applications of AR in surgery have primarily focused either on intra-operative visualization or pre-operative planning. There is currently no AR study focusing on intra-operative streaming during skull base surgery. This study is a crucial step in creating the virtual OR by focusing on streaming the aforementioned display information into an AR headset display, verifying its usability with surgeons on standardized tasks, and validating its clinical effectiveness during skull base surgery.
