喉癌术后喉狭窄患者喉重建术后的嗓音分析

Voice analysis of patients receiving second stage reconstruction of laryngostenosis after partial iaryngectomy for laryngeal cancer

目的:分析喉癌术后喉狭窄患者行颈前旋转肌皮瓣喉重建术后的嗓音康复情况。方法:应用Dr.Speech嗓音分析系统对19例喉癌术后喉狭窄患者喉重建术后的嗓音参数,包括基频(F_0)、基频微扰(Jitter)、振幅微扰(Shimmer)及声门噪声能量(NNE)值进行分析,并与喉重建术前以及成人喉乳头状瘤15例、声带息肉20例、正常人20例进行对比。结果:喉癌术后喉狭窄患者喉重建后的F_0较术前有显著上升(P<0.05),而Jitter、Shimmer及NNE值较术前均明显下降(P<0.05);F_0较喉乳头状瘤组有显著下降(P<0.05);与声带息肉组相比,F_0、Jitter均显著下降(P<0.05);与正常组比较,Jitter、Shimmer及NNE值均明显上升(P<0.05)。结论:喉癌术后喉狭窄患者行颈前旋转肌皮瓣喉重建术后的嗓音较术前有明显改善,能获得较好的嗓音功能。

Objective：To analyze the voice rehabilitation of the patients receiving second stage reconstruction with rotatory myocutaneous flap for laryngostenosis after partial laryngectomy or extended partial laryngectomy for laryngeal cancer. Methods： Nineteen patients receiving second stage reconstruction for laryngostenosis were subjected to voice assessment by Dr. Speech software; the values of F0 ,Jitter, Shimmer and NNE were calculated;the results were compared with before the second stage reconstruction and 15 adult patients with laryngeal papilloma, 20 patients with vocal polyp and 20 normal controls. Results： The F0 value of the patients who undergone second stage reconstruction was obviously higher than that before the second stage reconstruction（P〈0.05）, and the Jitter, Shimmer and NNE values were obviously lower than those before the second stage reconstruction（P〈0. 05）. The post-construction F0 value was obviously lower than that of patients with laryngeal papilloma（P〈0.05）; the post-construction F0 and Jitter values were obviously lower than those of patients with vocal polyp （P〈0.05）; the post-construction Jitter,Shimmer and NNE values were obviously higher than those of normal controls （P~ 0.05）. Conclusion： The voice quality of the patients receiving second stage laryngeal reconstruction has been greatly improved and the patients can regain satisfactory voice function.
