About

Satoshi Koyama is a pioneering surgeon whose work has fundamentally advanced the field of transoral robotic surgery (TORS) for head and neck cancers, particularly in Japan. His research focuses on expanding the feasibility and safety of minimally invasive approaches for pharyngeal, laryngeal, and thyroid cancers, aiming to preserve critical functions like speech and swallowing without compromising oncologic outcomes. Koyama’s landmark 2015 study, cited 17 times, was among the first to demonstrate the potential of the da Vinci Surgical System for pharyngeal cancer in Japan, laying the groundwork for broader adoption. He further refined patient selection by identifying preoperative predictors of difficult hypopharyngeal exposure (12 citations), a key technical barrier to TORS. Notably, Koyama introduced an innovative ultrasound-guided transoral approach for retropharyngeal lymph node metastasis from thyroid cancer (9 citations), offering a less morbid alternative to traditional open surgery. Most recently, his 2021 work used high-resolution manometry to objectively evaluate post-operative swallowing function, providing crucial data to validate functional outcomes. Through these contributions, Koyama has established himself as a leading voice in the evolution of transoral surgery, directly impacting how surgeons approach complex head and neck tumors.
