外視鏡（ORBEYE）による微小血管減圧術

Microvascular Decompression Surgery Using Exoscope（ORBEYE）

Point

・ORBEYEは微小血管減圧術において，①術者の疲労軽減，②さまざまな方向からの術野観察，③広い術野スペース，④高い教育的効果という長所を有している．

・視軸と操作軸の異なる手術に慣れることが術者にとって必要である．

　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.
