N2 - To clarify the phonation dynamics in voice disorders, we aerodynamically evaluated phonation during vocal attacks in 68 patients with vocal cord lesions and 12 controls with normal larynges. The patients with polypoid cords or glottic cancer showed shortening of the time between the increase in the subglottic pressure and the vocal attack (PS-I time), the rise time, a high subglottic pressure and hard attacks. Patients with recurrent nerve palsy showed slight shortening in the PS-I time, the rise time, a slightly higher subglottic pressure than in the control and patients with mild attacks.
