【摘要】 目的 :探讨计算机辅助声学分析在诊断喉癌及评价喉癌术后发声客观声学上的应用价值。方法 :以 18～ 65岁经检查无喉疾病 50例为正常组。以 4 0例喉癌患者为喉癌组 ,手术方式有声带切除术 ,垂直喉部分切除术 ,次全喉切除术和近全喉切除发音管成形术 ,分别于术前及术后 1～ 2个月测试。以各种原因引起的喉返神经麻痹 2 0例为对照组 ,各组均用声图谱分析仪检测。结果 :发i音时喉癌组术前、术后声学参数 ,如频率均值 ,平均微扰、频率微扰商、振幅微扰商、谐噪比、音调微扰系数与正常组差异有显著性 (P <0 0 5) ,喉返神经麻痹组除频率均值与正常组差异有显著性 (P <0 0 5)外 ,余无明显差异。发a音时 ,除喉癌组术前音调微扰系数外 ,余者差异均有显著性 (P <0 0 5)。结论 :喉癌患者发音参数的频率均值、平均微扰、频率微扰商、振幅微扰商、谐噪比及音调微扰系数与正常组差异有显著性 (P <0 0 5)。发声参数是评价喉癌患者发声客观声学的敏感指标。更多还原

【Abstract】 Objective: To investigate the value of computer assistant in diagnosis and evaluation vocal function of laryngeal carcinoma.Method:40 larygeal cancer patients who had accepted cordectomy,vertical partial laryngectomy,subtotal laryngectomy and voice production fistula operation were inspected by vocal map analyser before and after operation,50 normal peoples and 20 patients who had recurrent laryngeal nerve paralysis were also inspected as control groups.Result:The acoustic parameters such as frequency,jetter,shimmer,harmonics-to-noise ratios were all significantly higher in laryngeal group than those in control groups.Conclusion:The acoustic parameters mentioned above are sensitive parameters in the evaluation of vocal function of laryngeal carcinoma.更多还原
