Study on the effect of voice training on postoperative voice recovery in patients with vocal cord polyps
Objective To study the impacts of voice training on vocal function and hospital satisfaction degree after vocal cord polyp surgery,in order to analyze the overall treatment effect.Methods This study was a randomized controlled trial.A total of 96 patients with vocal cord polyps admitted to Dongguan Houjie Hospital from June 2020 to December 2023 were divided into an observation group(48 cases)and a control group(48 cases)according to the random number table method.The control group,25 males and 23 females,aged 35-68(41.23±5.24)years,received routine nursing intervention after vocal cord polyp surgery.The observation group,22 males and 26 females,aged 33-66(42.15±5.32)years,received voice training after vocal cord polyp surgery.The normalized noise energy(NNE),fundamental frequency perturbations(Jitter),amplitude perturbations(Shimmer),and overall patient satisfaction were recorded and analyzed before intervention and 1 week after intervention.Statistical methods used were x2 test and t test.Results After intervention,the scores of five items of voice disorder index of the observation group("It is difficult for others to hear my voice","hoarse vocal cords limit my social life","I feel that I can't keep up in conversation","my voice sounds hoarse and dry",and"I feel that I am less outgoing than before")were all lower than those of the control group,with statistically significant differences(t=3.57,4.90,4.35,7.70,and 2.24,all P＜0.05).The NNE,Jitter,and Shimmer of the observation group were lower than those of the control group[(-9.62±4.28)points vs.(-11.45±3.18)points,(0.23± 0.06)points vs.(0.33±0.08)points,(1.25±0.44)points vs.(1.78±0.65)points],with statistically significant differences(t=2.18,6.37,and 3.12,all P＜0.05).The overall patient satisfaction in the observation group was higher than that in the control group[85.42％(41/48)vs.58.33％(28/48)],with a statistically significant difference(x2=3.49,P＜0.05).Conclusion Voice training can effectively improve the laryngeal function in patients with vocal cord polyps,alleviate the voice disorders,and restore the voice function,with high overall patient satisfaction,which has high promotion and application value.
