OBJECTIVE: To evaluate functional outcomes following transoral robotic surgery for head and neck cancer. STUDY DESIGN: Case series with planned data collection. SETTING: Academic hospital. SUBJECTS AND METHODS: Between March 2007 and December 2008, 54 of 62 candidate patients underwent transoral robotic tumor resection. Outcomes include airway management, swallowing (MD Anderson Dysphagia Inventory), and enterogastric feeding. RESULTS: Tumors were most commonly oropharynx (61%) or larynx (22%) and T1 (35%) or T2 (44%). Many received radiotherapy (22% preoperatively, 41% postoperatively) and chemotherapy (31%). Endotracheal intubation was retained (22%) for up to 48 hours, tracheostomy less frequently (9%), and all were decannulated by 14 days. Most commenced oral intake prior to discharge (69%) or within two weeks (83%). A worse postoperative Dysphagia Inventory score was associated with retained feeding tube ( P = 0.020), age >60 ( P = 0.017), higher T stage ( P = 0.009), laryngeal site ( P = 0.017), and complications ( P = 0.035). At a mean 12 months' follow-up, 17 percent retained a feeding tube (9.5% among primary cases). Retained feeding tube was associated with preoperative tube requirement ( P = 0.017), higher T stage ( P = 0.043), oropharyngeal/laryngeal site ( P = 0.034), and recurrent/second primary tumor ( P = 0.008). Complications including airway edema (9%), aspiration (6%), bleeding (6%), and salivary fistula (2%) were managed without major sequelae. CONCLUSION: Transoral robotic surgery provides an emerging alternative for selected primary and salvage head and neck tumors with low morbidity and acceptable functional outcomes. Patients with advanced T stage, laryngeal or oropharyngeal site, and preoperative enterogastric feeding may be at increased risk of enterogastric feeding and poor swallowing outcomes.
