Abstract:
Objective:To explore the correlation between bolus of different viscosity and swallowing physiological components,as well as penetration and aspiration,in patients with dysphagia after radiotherapy for nasopharyngeal carcinoma.Method:Total 67 patients with dysphagia after NPCR were evaluated by videofluoroscop.They were required to swallow 5 ml bolus per mouth,in the order of medium-low-zero-high consistency.Modified barium swal-low impairment profile(MBSImP)and penetration-aspiration scale(PAS)were used for semi-quantitative analysis.Result:Wide probability ranges(＞0.2)can be observed between different swallowing tasks for 7 physiologi-cal components:oral residue,initiation of pharyngeal swallow,laryngeal elevation,laryngeal vestibular clo-sure,pharyngeal contraction,tongue base retraction,and pharyngeal residue.The risk of penetration and aspira-tion increased with lower viscosity.There was a significant positive correlation between the penetration aspira-tion scale and epiglottic movement,laryngeal vestibular closure,bolus transpor,initiation of pharyngeal swal-low and tongue base retraction.Conclusion:The performance of swallowing physiological components in patients with dysphagia after NPCR are closely related to the viscosity of the bolus being swallowed.
