对于发音困难的患者,若声带无明显病变可见,应进一步用实验室方法检查。本文概述并评价了当今在临床上应用的一些实验室检查法。一、声描记术:是一种声音的基音频率和元音的图示描记,在短时间内就能记录到基音的频率和振幅的资料,以识别任何声门运动紊乱。事实上,是复杂的声门运动形式用图解显示,而每次治疗的进展和有效的手术治疗均可借以作比较。二、发音气流:应用电子计算机,在数秒钟 For patients with dysarthria, vocal cord lesions were visible, should be further examined by laboratory methods. This article outlines and assesses some of the laboratory tests currently used clinically. First, the tracheostomy: is a voice of the pitch frequency and vowel pictorial tracings, in a short period of time can be recorded to pitch frequency and amplitude of the information to identify any glottis movement disorders. In fact, the complex form of glottis movement is illustrated graphically, and the progress of each treatment can be compared to effective surgical treatment. Second, the pronunciation of airflow: the application of electronic computers, in a few seconds
