Aerodynamic Parameters and the Airflow Regression Slope (ARS) in Patients with Vocal Polyps before and after Laryngomicrosurgery according to Perceptual Judgment

Phonation occurs when vocal fold vibrations are initiated and maintained by an interaction between the respiratory and phonatory systems [1]. The vocal folds must be in good condition for the voice to be satisfactory. Pathological conditions of the vocal folds are associated with voice deterioration. Voice disorders include alterations in vocal fold closure or muscle activation during vocal fold vibration; patients seek to comPurpose: The aims of this study were to explore changes in aerodynamic measures after vocal polyp removal and to determine whether the airflow regression slope (ARS) was a useful aerodynamic measurement.
