Transoral robotic surgery with free flap reconstruction: Functional outcomes of 241 patients at a single institution

Abstract

AbstractBackgroundTransoral robotic surgery (TORS) for oropharyngeal malignancy optimizes oncologic outcomes while preserving functionality. This study identifies patterns of functional recovery after TORS with free flap reconstruction (FFR).MethodsRetrospective cohort study at a tertiary care center of patients with primary oropharyngeal tumors treated with TORS with FFR between 2010 and 2022. Patients were categorized into: adjuvant chemoradiation or radiation, or no adjuvant therapy (NAT). Functional outcomes were measured by functional oral intake scale (FOIS).Results241 patients were included. FOIS declined at first postoperative appointment (median = 7.0 to 2.0, IQR = [7.0, 7.0], [2.0, 4.0]), and progressively improved to 6.0 (5.0, 6.0) after 1 year, with NAT having the highest FOIS (7.0, p < 0.05). Predictors of poor long‐term FOIS included RT and hypoglossal nerve (CN XII) involvement (p < 0.05).ConclusionsTORS with FFR leads to good long‐term function with minimal intake restrictions. Radiation therapy and CN XII involvement increase risk of worse functional outcomes.
