OBJECTIVES: The current trend in managing laryngeal and hypopharyngeal cancer is to perform organ preservation therapy, which improves quality of life and decreases treatment-related morbidity. Transoral robotic surgery (TORS) can overcome the limit of "line of sight" often met in classic transoral procedure. We utilized a robotic surgical system to evaluate the feasibility and oncologic safety of transoral partial pharyngectomy and laryngectomy. MATERIALS AND METHODS: TORS was performed by using a "da Vinci surgical robot" (Intuitive Surgical, Inc., Sunnyvale, CA). An FK retractor (Gyrus Medical Inc., Maple Grove, MN) was used to expose the cancerous lesion transorally, and an endoscopic arm was introduced through the oral cavity with two instrument arms placed 30 degrees apart from the endoscopic arm. We performed TORS on 1 patient with pyriform sinus carcinoma and 4 patients with glottic carcinoma as a prospective human trial. RESULTS: Average surgical time measured was 39 minutes, including an average of 25 minutes used for locating the robotic surgical system in place and exposing the lesion. TORS can provide a magnified three-dimensional view and overcome the limitation resulting from the "line of sight" that hinders the classic transoral procedure. All surgical resection margins were free of carcinoma. There were no perioperative complications, and also, no mortality due to the surgical procedure. CONCLUSIONS: This study demonstrates that the application of TORS for partial pharyngectomy and partial laryngectomy is technically feasible and safe.
