摘要
目的 探讨发不同元音 / / /a :/ /i:/时电声门图参数值是否有差异 ,明确其中哪个元音对电声门图检查更为合适。方法 对 118例受试者进行了电声门图检查 ,其中正常人 40例 ,病理嗓音组 78例 ,对发三种不同元音/ / /a :/ /i:/时电声门图参数频率微扰、振幅微扰、声门噪声能量、基频方差、接触率、接触率微扰、接触幂、接触幂微扰进行了比较并经统计学处理。结果 (1) 4 0例正常人发三种不同元音时 ,电声门图参数值均无统计学差异。 (2 ) 78例病理嗓音患者 (声带息肉 ,声带小结 ,声带囊肿 ,慢性声带炎 )发 / /和 /a :/音的电声门图参数值无统计学差异 ,而发 /i:/音时频率微扰 ,振幅微扰 ,声门噪声能量和接触率微扰明显低于 / /和 /a :/音 (P <0 .0 1、P <0 .0 1、P <0 .0 5、P<0 .0 5 ) ,而接触率则较 / /和 /a:/音时高 (P <0 .0 1)。结论 在病理状态下 ,发 /i:/音更易受代偿能力的影响 ,从而掩盖电声门图参数值的病理特征 ,因此作电声门图时 ,声样的选择应首选 / /和
Objective To investigate whether there are difference on electroglottography parameters with different vowel //,/a:/,/i:/ and decide which is the most suitable vowel to the EGG. Methods 118 testes were evaluated with EGG , including 40 normal and 78 abnormal subjects. Each parameters such as Jitter, Shimmer, NNE, SDF,CQ, CQP, CI, CIP were compared with three different vowels. Results (1)There were no differences between three vowels on EGG parameters in 40 normal subjects. (2)78 patients (vocal polyp, vocal nodules, vocal cords cyst, chronic chorditis et al.)were included, their parameters with // and /a:/ had no difference ( P >0.05), while the Jitter, Shimmer, CQP, NNE with /i:/ were evidently lower than that // and /a:/ ( P <0.01, P <0.01, P <0.05, P <0.05), but the CQ was much higher than that with // and /a:/ ( P <0.01).Conclusion The patients with pathologic voice/i:/ is easier to compensate the disease than with // and /a:/, so // and /a:/ is the preferred selection to EGG test.
