The purpose of this study was to determine the clinical value of subglottic pressure (SGP) in normal and dysphonic subjects. "The airway interrupted method" was used to measure the intra-oral pressure. Voice samples from 60 healthy subjects and 79 dysphonic patients were recorded under normal conditions of pitch and intensity. In normal subjects, age and gender have no significant impact on mean and peak SGP. The peak SGP measurements are significantly higher in dysphonic patients and could be included in the basic clinical set of objective voice parameters. No differences could be shown between pre- and postoperative assessments or between groups of dysphonic patients.
