Abstract

Transoral robotic surgery (TORS) has been used as a novel procedure for squamous cell carcinoma of the laryngopharyngeal cancers with encouraging outcomes. The safety, feasibility, and efficacy regarding this approach have previously been demonstrated. There are several studies proposing the benefit of combining TORS with carbon dioxide (CO2) laser in resecting upper aerodigestive tract tumors. We report a series of patients with hypopharyngeal carcinoma treated with primary TORS with or without the flexible carbon dioxide (CO2) laser. All TORS resections were completed without any intraoperative complication. None required conversion to an open procedure. Clinical outcomes in this preliminary analysis indicate that magnified view, 3D visualization with the wristed instruments and tremor reduction technology of robotic experience, allow en bloc resection of early stage hypopharyngeal cancers. TORS with CO2 laser is a promising, minimally invasive surgical alternative for the treatment of hypopharyngeal tumors with comparable oncologic outcomes.
