Abstract:
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.
