儿童扁桃体腺样体切除术对嗓音影响的研究

Effects of adenotonsillectomy on speech spectrum in children

目的通过评估儿童扁桃体腺样体切除术前后的嗓音特性,为建立更合理的扁桃体腺样体肥大的管理和治疗手段提供帮助。方法评估4～14岁儿童扁桃体腺样体切除术20例。手术前后分别采用多维嗓音分析(Multi-Dimensional Voice Program,MDVP,KayElemetrics)软件做嗓音评估。结果扁桃体腺样体切除术后,所有嗓音参数与术前相比均有改变,其中基频、清浊率、嗓音骚动指数等参数术后与术前相比变化明显。结论术后嗓音参数变化客观的说明扁桃体腺样体切除术改变了共鸣腔的结构,影响了嗓音的质量。而MDVP可为分析嗓音、评估扁桃体腺样体切除术后嗓音的预后提供客观手段。

OBJECTIVE To evaluate the change in acoustic features of speech after adenotonsillectomy in children and to establish reasonable methods of management and rational therapeutic approach. METHODS Before and after operation,acoustic analysis with Multi-Dimensional Voice Program （MDVP,Kay Elemetrics）was examined in 20 children,aged between 4 and 14 years old,with enlarged palatine tonsils and hypetrophic adenoids. The following parameters were estimated：average of fundamental frequency（F0）,Jitt,Shim,noise to harmonics ratio （NHR） , voice turbulence index （VTI） , soft phonation index （SPI） ,degree of voiceless （DUV） and degree of voice breaks （DVB） . RESULTS All the data of the parameters were improved after the operation, especially in F0, NHR and VTI. CONCLUSION The results provided by MDVP showed that the adenotonsillectomy change the structure of resonance cavity and affect the quality of voice consequently.
