声带癌、声带息肉和声带麻痹治疗前后临床喉发音功能评价研究

Phonatory Function Evaluation of Pathological Voice ln Patients' Pre-and Post-treatment

目前尚无一种较科学实用的喉发音功能评估方法用于临床.本文对声带癌、声带息肉和声带麻痹患者各30例,在临床治疗前后进行嗓音声学分析、喉平均呼气流率测定、频闪喉镜检查及嗓音心理听觉评价.对所获参数进行统计学分析,得出各种喉病治疗前后发音功能检测参数的改变及各参数的内在相关性.研究结果表明该方法科学实用是一种较好的喉发音评价方法,值得推广应用.

The subjets were 90 patients, 47 males and 43 females with laryngeal diseases. Ofthese 90 patients, 30 had glottic carcinoma; 30 vocal fold polyp; and 30 vocal fold paralysis. A setof test have been routinely used for dysphonia patients in this study. The test include aerodynamicmeasurements, phonatory ability test, stroboscopic examination, psychoacoustic evaluation andtape recording of voice samples. The purpose of this paper is to determine their usefulness in mon-itoring effects of treatment, to investigate the relationship between the parameters obtained bythose tests.Acoustical analysis of voice showen that acoustic parameter was significantly greater forparalysis than for carcinoma and polyp (P<0. 01). It did not differ significantly between carcino-ma and polyp cases. Most of the patients whose voice was improved post-treated presented a de-crease in PPQ,APQ and NNE. The results of the present study indicate that PPQ, APQ and NNEcan be useful parameters with which to monitor the effect of treatment. Relationships between a-coustical parameters and other clinical tests that investigate physiological, physical, aerodynamic,vibratory, psychoacoustic and functional correlates are important because acoustical characteristicsshould reflect thest correlates. The results reveal some important relationships between the pa-rameters of different levels of voice production.
