Transoral surgery using a novel single-port flexible endoscope system

Area of Science:

• Otolaryngology
• Surgical Robotics
• Minimally Invasive Surgery

Background:

• Transoral tumor resection is challenging due to narrow anatomical spaces.
• Effective visualization and access are critical for successful pharyngeal and laryngeal procedures.

Purpose of the Study:

• To evaluate a novel computer-assisted flexible endoscopic robotic system for transoral visualization and resection.
• To assess the feasibility and effectiveness of the Medrobotics Flex System in cadaveric models.

Main Methods:

• Six human cadavers were used for the study.
• Two surgeons performed four basic procedures: tonsillectomy, base of tongue resection, hemi-epiglottectomy, and false vocal cord resection.
• The Medrobotics Flex System, an operator-controlled flexible endoscope robotic system, was utilized.

Main Results:

• Successful visualization and resection were achieved in all procedures.
• The system provided appropriate exposure and access within the pharynx and larynx.
• Surgeons noted a learning curve associated with operating the system and performing procedures.

Conclusions:

• The Medrobotics Flex System is a promising tool for transoral resections in the pharynx and larynx.
• The system offers advantages in visualization, access, and resectability compared to conventional methods.
