Transoral radical tonsillectomy and retropharyngeal lymph node dissection with a flexible next generation robotic surgical system.

Abstract

The purpose of this study was to describe the use of a novel flexible, single-arm robot in performing a transoral radical tonsillectomy and retropharyngeal lymph node dissection. A 63-year-old man with a T1N2bM0 (American Joint Committee on Cancer seventh edition classification) squamous cell carcinoma (SCC) of the left tonsil underwent a transoral robotic radical tonsillectomy and retropharyngeal lymph node dissection, followed by a left selective neck dissection of levels I to IV. The tonsillar tumor was removed completely with a negative margin that was followed by a dissection and removal of a retropharyngeal lymph node, completed with primary closure of the site. A left selective neck dissection was then performed. The patient was tolerating an oral diet on postoperative day 1 and had no robotic or surgically related complications at 30-day follow-up. It is feasible and safe to use this novel, flexible, single-arm robot in performing a transoral robotic radical tonsillectomy and retropharyngeal lymph node dissection.
