Objectives: This study aims to compare the motility of the pharynx and UES in patients with UVFI before and after thyroplasty type I. Methods: We prospectively studied 15 patients with UVFI that underwent thyroplasty type I. Subjects were divided according to the topography of vagal injury and presence of dysphagia. High resolution manometry (HRM) was performed before and 30 days after surgery. Time and pressure manometric parameters at the topography of the velopharynx, epiglottis and UES were recorded. Results: Dysphagia was present in 67% of patients. 73% had lower vagal injuries. Manometric parameters did not change after thyroplasty for the whole population. The group of dysphagic patients; however, had an increase in residual pressure at the UES after thyroplasty (1.2 vs. 5.2 mmHg - p=0.05). Patients with low vagal injury developed higher peak pressure (100 vs. 108.9 mmHg - p=<0.001); lower rise time (347 vs. 330 ms - p=0.04); and higher up stroke (260 vs. 266.2 mmHg/ms p= 0.04) at the topography of the velopharynx after thyroplasty. Conclusion: Pharyngeal motility is affected by thyroplasty type I in patients with dysphagia and low vagal injury.
