About

Dr. Tomomasa Hayashi is a leading figure in head and neck surgical oncology, whose work has significantly advanced the precision of minimally invasive cancer treatments. His primary research focuses on the integration of advanced endoscopic imaging with robotic surgery, specifically for oropharyngeal and laryngopharyngeal cancers. Dr. Hayashi’s most notable contribution is pioneering the use of magnifying endoscopy with narrow band imaging (ME-NBI) to delineate tumor margins during transoral robotic surgery (TORS). This technique directly addresses a critical challenge in TORS: determining the exact extent of resection in the complex anatomy of the laryngopharynx. By enabling surgeons to visualize superficial cancerous changes in real-time, his work has improved the accuracy of tumor removal while preserving healthy tissue, a balance vital for both oncologic control and functional outcomes. His seminal 2014 paper on this method has garnered 23 citations, establishing a foundational protocol for image-guided robotic surgery. Dr. Hayashi’s research bridges the gap between diagnostic endoscopy and surgical intervention, offering a practical, high-impact solution that enhances the safety and efficacy of TORS for patients worldwide.
