摘要：

The vocal function of 126 patients with sulcus vocalis was evaluated with the use of a test battery of multidimensional evaluation items. Of the 126 patients, 31 had a unilateral sulcus and 95, bilateral lesions. The results were as follows. 1) The majority of the patients had a mild degree of hoarseness with a breathy quality. 2) An incomplete glottic closure, a small vibratory amplitude, and a small mucosal wave were frequently observed in the stroboscopic examination. 3) The maximum phonation time, fundamental frequency range, and sound pressure level range of phonation were decreased, whereas the airflow during phonation was increased. 4) The pitch perturbation quotient, amplitude perturbation quotient, and normalized noise energy were increased. 5) Abnormal test results were more frequent and more marked for bilateral lesions than for unilateral lesions. © 1990, SAGE Publications.
