扁桃体腺样体切除术对患儿嗓音特征及共鸣参数的影响
Effects of tonsillectomy and adenoidectomy on vocal characteristics and resonance parameters in children
目的 探讨扁桃体腺样体切除术对患儿嗓音特征及共鸣参数的影响。方法 选取行扁桃体腺样体肥大切除术的61例患儿为实验组,同期在本院健康体检儿童61例为健康对照组。所有儿童均行多维嗓音学检查,比较两组及患儿手术前后多维嗓音学参数:基频(fundamental frequency, F0)、基频微扰(Jitter)、振幅微扰(Shimmer)、振幅变化系数(amplitude variation coefficient, vAm)、噪谐比(noise harmonic ratio, NHR)、嗓音紊乱指数(voice turmoi index, VTI)、软发音指数(soft production index, SPI)、共振峰频率(formant frequencies, F1~F3)及带宽(bandwidths, B1~B3)。结果 术前,实验组vAm高于健康对照组(P<0.001),实验组F0、Jitter、Shimmer、NHR、VTI、SPI与对照组比较差异无统计学意义(P>0.05)。与术前1 d比较,术后15 d患儿vAm降低,术后30 d的vAm、NHR降低(P均<0.001),术后30 d患儿共振峰频率值及带宽降低,差异有统计学意义(均P<0.001)。结论 腺样体及扁桃体切除术能够降低患儿vAm、NHR、共振峰频率值及带宽。
Objective To explore the effects of tonsillectomy and adenoidectomy on vocal characteristics and resonance parameters in children. Methods A total of 61 children undergoing tonsillectomy and adenoidectomy, and 61 healthy children who underwent physical examination in the hospital were enrolled as experimental group and healthy control group, respectively. The multi-dimensional vocal examination was performed for all children to compare multi-dimensional vocal parameters [fundamental frequency (F0), Jitter, Shimmer, amplitude variation coefficient (vAm), noise harmonic ratio (NHR), voice turmoi index (VTI), soft production index (SPI), formant frequencies (F1-F3), bandwidths (B1-B3)] between the two groups before and after surgery. Results Before surgery, vAm in experimental group was higher than that in healthy control group (P<0.001), but there was no significant difference in F0, Jitter, Shimmer, NHR, VTI or SPI between the two groups (P>0.05). Compared with 1 d before surgery, vAm was decreased at 15 d after surgery, vAm and NHR were decreased at 30 d after surgery (all P<0.001), formant frequencies and bandwidths were decreased at 30 d after surgery (all P<0.001). Conclusion Adenoidectomy and tonsillectomy can reduce vAm, NHR, formant frequencies and bandwidths in children.
