Abstract
Dysphagia remains an unsolved problem for patients with oral cavity cancer who have undergone surgery. This randomized controlled trial was conducted to determine the effect of oral exercise in addition to standard general care and diet counseling on the physiology of swallowing. Fifty patients (25 in each group) with oral and oropharyngeal cancer who underwent tumor resection, neck dissection, and reconstruction were enrolled in this study. The Rosenbek penetration-aspiration scale and modified barium swallow study were administered at 1 and 4 month(s) postoperatively. We observed significant improvements in the intervention group regarding the penetration-aspiration scale (P = .037), and oral and pharyngeal residue with thickened boluses (Nectar P < .001, Honey P < .001, and Pudding P < .001). In conclusion, oral exercise significantly improves the postoperative swallowing function of patients with oral cavity cancers.
