Objectives: To assess the feasibility and safety of performing robot-assisted resections of head and neck tumors, and to predict which variables lead to successful robot-assisted resection and better functional outcome. Design: Prospective nonrandomized clinical trial. Setting: Academic tertiary referral center. Patients: Thirty-six patients with oral cavity, oropharyngeal, hypopharyngeal, or laryngeal tumors. Intervention: Robot-assisted resection of indicated tumors. Main Outcome Measures: Ability to perform robot-assisted resection, final pathologic margin status, ability to extubate postoperatively, need for tracheotomy tube, and need for gastrostomy tube. Any clinically significant complications were recorded. Results: Thirty-six patients participated in the study. Eight patients had previously been treated for head and neck cancer. Twenty-nine patients (81%) underwent successful robotic resection. Negative margins were obtained in all 29 patients. Twenty-one of 29 patients were safely extubated prior to leaving the operating room. One patient required short-term tracheotomy tube placement. A total of 9 patients were gastrostomy tube dependent (2 preoperatively, 7 postoperatively). Factors associated with successful robotic resection were lower T classification (P = .01) and edentulism (P = .07). Factors associated with gastrostomy tube dependence were advanced age (P = .02), tumor location in the larynx (P
