| Objective: To study the effectiveness of tongue pressure resistance feedback training system combined with balloon dilatation in the treatment of hypoharyngeal dysplasia. Methods: Thirty patients with hypoharyngeal dysplasia were randomly divided into the tongue pressure resistance training group, the balloon dilatation group and the combined group (n=10 each). All patients in three groups were given routine rehabilitation training for swallowing dysfunction, including cold stimulation and swallowing muscle related training, electrical stimulation of pharynx muscles, and Mendelssohn methods. Additionally, the patients in tongue pressure resistance group were given tongue pressure resistance feedback training (tongue pressure resistance training system), those in balloon dilatation group were given balloon dilatation, and those in combined group were given tongue pressure resistance training combined with balloon expansion training. Videofluoroscopic swallowing study (VFSS) and functional oral intake scale (FOIS) were used as assessment methods, and functional evaluations were made before and after treatment. Changes in the way they ate were also assessed. Results: The VFSS and FOIS scores of the three groups after treatment were significantly higher than those before treatment (P<0.05). The VFSS score and FOIS score in the combined group were higher than those in the tongue pressure resistance feedback group and the balloon dilatation group after treatment (P<0.01). The VFSS score and FOIS score in the balloon dilatation group after treatment were higher than those in the tongue pressure resistance feedback group (P<0.01). After treatment, patients in the combined group, tongue pressure group, and balloon dilatation group had significantly higher oral intake after treatment than before treatment (P<0.05). There was no significant difference between the combined group and the balloon dilatation group. The proportion of oral eating was significantly higher in the combined group and the balloon dilatation group than that in the tongue pressure group (P<0.05). Conclusion: Tongue pressure resistance feedback training combined with balloon dilatation can improve dysphagia caused by hypoharyngeal dysplasia and improve the quality of life of patients. |
