[Augmented Reality in head and neck surgery]

Augmented Reality (AR) is an emerging technology that supports surgeons in spatial reasoning during clinical procedures. The most fascinating applications include visualizations of anatomical structures, cross-sectional images or surgical approaches, which can be displayed directly on the patient in combination with the real world. The aim of this narrative review is to outline the state of the art and future directions of AR in head and neck surgery. Particular attention is paid to explaining the potential and the difficulties that still need to be solved with this new technology.
