RESUMO
Objective@#The aim of this study is to investigate the effect of fibreoptic endoscopic of sallowing （FEES） in the assessment of pharyngeal dysphagia in post-irradiated patients with nasopharyngeal carcinoma.@*Method@#Fifty-three NPC patients with post-irradiated underwent FEES and video fluoroscopy（VF）.The results were analyzed using the Bolus Residue Scale and Rosenbek's penetration aspiration scale.@*Result@#The agreement in the detection of penetration and aspiration between FEES and VF of liquid（κ=0.56, 95%CI 0.38-0.73） and porridge（κ=0.64, 95%CI 0.43-0.81） was "fair". The detection rates of penetration on FEES with liquid and porridge were 60% and 51%, the detection rates of aspiration on VF with liquid and porridge were 70% and 53%. There were no statistical differences. The agreement in the detection of pharyngeal residue between FEES and VF of liquid （κ=0.38, 95%CI0.12-0.62） and porridge （κ=0.66, 95%CI 0.44-0.86） was "fair". The detection rates of pharyngeal residue on FEES and VF with porridge were 43% and 45%, the difference was not statistically significant. The detection rates of pharyngeal residue on FEES and VF with liquid were 44% and 24%, and the difference was statistically significant.@*Conclusion@#FEES is an effective and valuable tool for evaluating pharyngeal dysphagia in post-irradiated patients with nasopharyngeal carcinoma.

RESUMO
Objective To study the effect of low frequency electric stimulation and urethral catheter balloon dilatation therapy on dysphagia in nasopharyngeal carcinoma(NPC)patients after radiation therapy. Methods Eighteen dysphagic NPC patients who had received radiation therapy were studied.They included 15 males and 3 females with a mean age of 49.5 years.Thirteen were being fed with a nasogastric tube and 5 with a gastmstomy tube.Low frequency electric stimulation was applied to the swallowing muscles and urethral catheter balloon dilatation therapy was used for the crieopharygeus muscle.Before and after treatment the effects were evaluated with a videofluoroscopic study of swallowing.Results Most swallowing function improved after treatment.After treatment the pharyngeal transit time of paste iodine and fluid iodine(diatriazoate)through the mouth and hypopharynx showed significant improvement.Displacement of the hyoid bone was significantly greater after treatment.Before treatment the incidence of pyriform sinus stasis and aspiration were 100%:after treatment these were 44.4%and 16.6% respectively.Videofluoroscopy showed that 7 cases had been cured(38.9%),9 cases had improved(50.0%)and 2 cases showed no effect(11.1%).In 15 cases the nasogastric or gastrostomy tube could be removed. Conclusion Low frequency electric stimulation and urethral catheter balloon dilatation can improve swallowing in NPC patients with dysphagia after radiation therapy.This treatment was easy to administer,safe and reliable.
