Characterization of very late dysphagia after chemoradiation for oropharyngeal squamous cell carcinoma

•Late dysphagia in oropharyngeal cancer after treatment is poorly characterized.•We report long-term dysphagia outcomes in patients treated with chemoradiation.•15.1% of patients had moderate dysphagia >2.5 years after treatment.•7.5% of these patients had dysphagia that worsened after one year out from treatment.•Radiation dose to the tongue may be a target to prevent this and should be further studied.
