Abstract:

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 χ² 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 (χ²=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.

摘要：

目的　研究嗓音训练对声带息肉患者术后嗓音功能和住院满意度的影响，并分析整体治疗效果。方法　本研究为随机对照试验。选取2020年6月至2023年12月东莞市厚街医院收治的声带息肉患者96例，采用随机数字表法分为观察组和对照组，各48例。对照组男25例，女23例，年龄35～68（41.23±5.24）岁，行声带息肉术后常规护理干预措施；观察组男22例，女26例，年龄33～66（42.15±5.32）岁，在声带息肉术后予嗓音训练护理措施。记录并分析干预前、干预1周后两组标准化噪声能量（NNE）、基频微扰（Jitter）、振幅微扰（Shimmer）和患者整体满意度。统计学方法采用χ²检验和t检验。结果　干预后，观察组嗓音障碍指数中5个条目评分（“别人很难听到我的声音”“声带嘶哑限制了我的社交生活”“我感到在交谈中话跟不上”“我的声音听上去嘶哑干涩”“我觉得自己不如以前外向”）均低于对照组，差异均有统计学意义（t=3.57、4.90、4.35、7.70、2.24，均P<0.05）；观察组嗓音功能指数中NNE、Jitter、Shimmer均低于对照组［（-9.62±4.28）分比（-11.45±3.18）分、（0.23±0.06）分比（0.33±0.08）分、（1.25±0.44）分比（1.78±0.65）分］，差异均有统计学意义（t=2.18、6.37、3.12，均P<0.05）；观察组患者满意度高于对照组［85.42%（41/48）比58.33%（28/48）］，差异有统计学意义（χ²=3.49，P<0.05）。结论　嗓音训练可有效改善声带息肉患者喉功能、减轻嗓音障碍、恢复嗓音功能，患者住院满意度较高，可临床推广应用。
