[Transoral resection of supraglottic laryngeal tumors with the Flex Robotic System].

The Flex Robotic System (Medrobotics, Raynham, MA, USA) allows flexible transoral endoscopic resection of head and neck tumors. The current article presents functional and first oncologic experiences with flexible transoral robot-assisted surgery for resection of supraglottic laryngeal tumors. From July 2014 to February 2020, supraglottic cancers in 32 patients (T1 = 11, T2 = 20, T3 = 1) were resected using the Flex Robotic System in the authors' clinic. Within a prospective clinical study, the feasibility, complications, and oncologic results were assessed. Tumors could be exposed, visualized, and successfully resected in all patients. In difficult-to-reach anatomic regions such as the aryepiglottic fold or petiole, the system provided a very good surgical overview. No serious adverse events occurred. Overall survival and local tumor control after 2 years were 88 and 94%, respectively. In conclusion, supraglottic tumors in difficult-to-reach areas have been successfully resected using the Flex Robotic System, with excellent local tumor control.
