Objective To explore the effect of teach-back combined with Wechat health education on the rehabilitation of postoperative dysphagia patients with posterior cranial fossa tumor. Methods A total of 43 dysphagia patients after posterior cranial fossa tumor operation admitting from January to June 2019 were taken as a control group, and another 43 patients admitting from July to December 2019 as an intervention group.The control group received health education utilizing routine method, while the intervention group received health education using teach-back combined with Wechat.The effect of intervention was evaluated at one week, one month and three months after the intervention. Results At one week after the intervention, the incidence of aspiration of the intervention group was significantly lower than that of the control group （P＜0.05）.At one month and three months after the intervention, the score of swallowing function of the intervention group were significantly lower than those of the control group （P＜0.05 for both）.The score of swallowing function of the two groups decreased with the extension of time, especially in the intervention group （P＜0.05）. Conclusion Application of teach-back combined with Wechat health education in postoperative dysphagia patients with posterior cranial fossa tumor, can effectively improve patients′ swallowing function, reduce the incidence of aspiration, which is beneficial to their physical rehabilitation.
