Abstract:Objective To investigate the application value of fibreoptic endoscopic evaluation of swallowing (FEES) and evaluate the correlation between dysphagia and radio-chemical therapy of nasopharyngeal cancer(NPC).Methods It was analyzed for the results of M.D.Anderson Dysphagia Inventory(MDADI), FEES and Video Fluoroscopic Swallowing Study(VFSS) in 37 patients with NPC.Results The positive rate of FEES detection was higher(70.27%) than that of VFSS detection(48.65%) for dysphagia, and the difference was statistically significant between them(P<0.05). FEES are consistent with VFSS (Kappa of 0.358). The consistency between FEES and MDADI (Kappa value of 0.340) was better than the consistency between VFSS and MDADI (Kappa value of 0.194).Conclusion FEES can be applied in the evaluation of dysphagia after the radio-chemical therapy of NPC, which is worth promotion in clinic.
