Abstract:
OBJECTIVE: To investigate the improvement of dysphagia after balloon dilatation and balloon swallowing at the vallecular space with a Foley catheter in stroke patients. METHODS: This study was conducted between May 1, 2012 and December 31, 2015, and involved 30 stroke patients with complaints of difficulty in swallowing. All patients underwent videofluoroscopic swallowing study (VFSS) before and after vallecular ballooning. VFSS was performed with a 4 mL semisolid bolus. For vallecular ballooning, two trainings were performed for at least 10 minutes, including backward stretching of the epiglottis and swallowing of a balloon located in the vallecular space, by checking the movement of the Foley catheter tip in real time using VFSS. RESULTS: After examination of the dysphagia improvement pattern before and after vallecular ballooning, laryngeal elevation (x-axis: pre 2.62±1.51 mm and post 3.54±1.93 mm, p=0.038; y-axis: pre 17.11±4.24 mm and post 22.11±3.46 mm, p=0.036), pharyngeal transit time (pre 5.76±6.61 s and post 4.08±5.49 s, p=0.043), rotation of the epiglottis (pre 53.24°±26.77° and post 32.45°±24.60°, p<0.001), and post-swallow pharyngeal remnant (pre 41.31%±23.77% and post 32.45%±24.60%, p=0.002) showed statistically significant differences. No significant difference was observed in the penetration-aspiration scale score (pre 4.73±1.50 and post 4.46±1.78, p=0.391). CONCLUSION: For stroke patients with dysmotility of the epiglottis and post-swallowing residue, vallecular ballooning can be considered as an alternative method that can be applied without risk of aspiration in dysphagia treatment.
