Compared with an operative microscope, the ORBEYE has several advantages, including fatigue reduction for the operator in a relaxed and head-up natural position, infinite access, wide working space, and high educational value owing to the 3D images shared by everyone. Microvascular decompression surgery(MVDS)has similar advantages. Although operators need to learn surgical skills using different visual and surgical axes, in my personal experience, 10 cases of MVDS were practical for acquiring the skill in terms of operation time. Moreover, arranging proper ORBEYE settings in the operating room is essential for the assistants' accurate support.
