How does a novel, flexible, single-port robotic surgical system for transoral tongue base resection compare to the current multiport, rigid-arm robotic surgical system?
Surgical workflow was more streamlined with the da Vinci Sp system, and the new capabilities of simultaneous dissection, traction, and counter traction allowed for improved dissection and vessel control.

Background: Currently, transoral robotic surgery, designed for cardiac and abdomino-pelvic surgery, is the only commercially available robotic surgical system for multidisciplinary treatment for oropharyngeal squamous cell carcinoma. The da Vinci Si surgical robot’s dimensions are larger than what would be ideal for head and neck surgery, and it utilizes three rigid instrument arms that must approach transoral anatomy from a sometimes troublesome trajectory outside of the surgical field. The newer da Vinci Sp provides three fully articulating instruments delivered through a single 25-mm cannula entry port.
Study design: Preclinical anatomic study of four human cadavers using the da Vinci Si and the da Vinci Sp surgical robots.
