Clinical Approach to Aerodynamic Assessment

Abstract

Aerodynamic assessment is undertaken to obtain information about vocal function via measurement of subglottal pressure and glottal airflow, i.e., glottal aerodynamics. As is the case with acoustic assessment, aerodynamic assessment can be accomplished with children of a variety of ages (Lotz et al. Int J Pediatr Otorhinolaryngol 26(2):165-72, 1993). Acoustic and aerodynamic measurements are often conducted concomitantly, and previously detailed suggestions for performing an acoustic assessment are appropriate.
