Abstract

Background

Transoral treatment of benign and malignant lesions of laryngopharynx has limitations in exposure and access, partially due to the endotracheal tube (ETT). With a proper airway control to tailor ventilation and maximize exposure, transoral Flex robotic surgery (FLEX), using its 3D camera and instruments, can expand its ability. Choosing the right ETT, including a novel concept of using jet ventilation (JV) in FLEX, and placement technique can allow augmentation of the advantages that robotic surgery offers.

Methods

Chart review of FLEX assisted procedures was performed. Attention was given to demographics, all events of airway manipulation and ventilation type, procedures performed and outcomes including adverse effects.

Results

Fifty-two patients underwent eighty procedures. The airway was manipulated sixty-four times to include 8 JV. All possible FLEX instruments including CO2 laser were used. Three novel possible indications for trans-oral robotic surgery including the feasibility of JV in FLEX procedures were shown.

Conclusions

Lesions of the tongue base, hypopharynx, larynx and trachea have the possibility to be managed with adequate exposure with minimal obstruction from ETT. Robotic HD camera permits both the surgeon and anesthesiologist to observe surgery and safely monitor the airway. An algorithm was developed for selecting ideal ventilation method for different procedures. The FLEX and the utilization of JV allows flexibility of two instruments without obstruction.
