Abstract

Background: Accuracy in neurosurgery is paramount. Referring to 2D screens adjacent to the surgical field costs surgeons time and cognitive effort which could increase the chance of error. Augmented-reality (AR) Microsoft Hololens-based neuronavigation systems hope to aid surgeons by overlaying postoperative and intraoperative information within the surgical field, most notably by providing a 3D hologram of the anatomy with a surgical path to it, hopefully increasing the chance of a successful surgical outcome.

Method: I conducted a literature review to understand the current state-of-play on how the Microsoft Hololens is being used in neurosurgery around the world.

Results: n = 16, 80% of papers in this literature review show that, as expected, accuracy is of vital interest, of which n = 13, 65% focus on accuracy of navigation and n = 3, 15% focus on accuracy of registration. n = 4, 20% focus on user experience of the AR system. Only n = 6, 30% of papers find the AR system is clinically accurate. More research is needed on real patients to test accuracy, with more ecological valid studies and higher participant numbers.

“We loved starting the Brew York Revolution with Chris. He helped us realise our ambitious expansion plan of opening York’s biggest craft beer venue just two years after we opened our brewery. His crowdfunding campaign raised £56k in 21 days with us increasing our target twice. It was amazing to get 41% more than our initial £40k target. He really supported us to take our business to the next level with great creative ideas, which were completely results focused and provided brilliant return on investment.”
