Abstract Objective To evaluate the swallowing status of nasopharyngeal cancer after radiotherapy .[Methods]The swallowing status of 106 patients with nasopharyngeal cancer 1 year before and after treatment was evaluated regularly .The evaluation methods included patient-reported dysphagia(PRD) ,observer-repor-ted dysphagia(ORD) and objective examination videofluoroscopy (VF) score .According to maximal ORD scores from 3 months to 12 months after radiotherapy ,all patients were divided into 5 groups .PRD and VF scores were compared among 5 groups .[Results] PRD scores except overall curse dimension of dysphagia de-grees in group 1 were obviously lower than those in other groups ,but there was no significant difference in dysphagia degree among group 2 ,3 ,4 and 5 .The positive rate of dysphagia according to PRD score was high-er than the positive rate of dysphagia according to ORD and VF scores .[Conclusion]Dysphagia as a objective symptom ,especially mild dysphagia may be underestimated by clinicians .Dysphagia of nasopharyngeal cancer after radiotherapy is likely to become one of the important tasks for our otolaryngology-head-neck surgeons .
