About

Nozomu Matsumoto is a pioneering figure at the intersection of otologic surgery and robotics, whose work is redefining the precision and safety of ear surgery. His research centers on developing robotic and computer-assisted systems for the delicate, restricted operative field of the middle and inner ear. Matsumoto’s major contributions lie in creating human-robot collaborative control systems for mastoidectomy, a technically demanding procedure. His seminal 2011 paper, which introduced an image-guided robotic mastoidectomy system, is a cornerstone of the field. This work implemented a "forbidden-region virtual fixture" to protect critical anatomical structures and a human-robot collaboration mode, allowing surgeons to retain control while benefiting from robotic precision. His 2015 study on semi-manual mastoidectomy further advanced this approach, demonstrating the practical application of collaborative control on temporal bone replicas. With over 30 combined citations for his key works, Matsumoto’s impact is evident. He also authored a comprehensive 2025 review highlighting recent advances in robotic platforms and clinical outcomes, solidifying his role as a leading voice in this emerging field. His early phantom experiments laid the groundwork for automatic mastoidectomy, showcasing his sustained commitment to translating robotic innovation into safer, more effective surgical care.
