目的探讨T1期声门区喉癌手术前后喉功能客观评价的方法。方法选择接受喉癌部分切除术的喉癌患者76例,分别于手术前后进行喉部功能评价,比较基频微扰(Jitter)、振幅微扰、谐噪比和标准声门噪声能量(NNE)等变化。结果术后患者声门区开放面积和声门后部最大横径较术前有明显减小,差异有统计学意义(P<0.05)。嗓音质量评估结果显示,手术前后基频微扰和谐噪比差异无统计学意义(P>0.05),但是振幅微扰和标准声门噪声较术前显著下降,差异有统计学意义(P<0.05)。结论 T1期声门区喉癌手术在切除肿瘤组织的同时,对喉部其他组织影响较小,能确保喉部术后良好的呼吸和发音功能。
Objective To evaluate the objective evaluation of laryngeal function in T1 glottic laryngeal carcinoma before and after operation. Methods Sixty-seven patients with laryngeal cancer undergoing partial laryngectomy were enrolled in this study. The laryngeal function was evaluated before and after the operation. The jitter, amplitude perturbation, harmonic ratio and standard glottal noise energy (NNE) Other changes. Results The open area of the glottic flap and the maximum transverse diameter of the glottis area were significantly decreased compared with those before operation, the difference was statistically significant (P <0.05). Vocal quality assessment showed that there was no significant difference in fundamental frequency and harmonic ratio before and after surgery (P> 0.05), but amplitude perturbation and standard glottal noise were significantly decreased compared with that before operation (P <0.05 ). Conclusion Tumor resection in T1 glotticus laryngeal cancer surgery has less effect on other tissues in the larynx and can ensure good respiratory and vocal function after laryngectomy.
