Objectives: How reconstruction affects function following total laryngectomy is unclear. This study seeks to determine whether reconstruction method is associated with differences in swallowing outcomes.
Methods: Retrospective review of reconstruction technique in patients undergoing TL was compared by pharyngeal transit time (PTT), patient-reported dysphagia (EAT-10), and diet-tolerated (FOIS).
Results: Ninety-five patients met inclusion criteria, with 40 patients (42.1%) undergoing primary closure and 55 patients (57.9%) undergoing tissue transfer. There was no difference in EAT-10 scores between the groups (P = .09). There was a significantly higher proportion of patients achieving oral diet (FOIS >3) with primary closure (P = .003). Patients undergoing PMC vs free flap had similar rates of g-tube dependency. Primary closure had the shortest PTT (1.89 seconds) compared to free flap (3.47-4.65 seconds) or PMC (5.1 seconds; P = .035).
Conclusions: When primary closure is achievable, these results suggest improved swallowing outcomes with better tolerance of oral diet and shorter pharyngeal transit times.
