Abstract
ObjectiveThe present study shows a systematic review of the literature, related to the clinical and investigative implementations of aerodynamic measurements of phonation: subglottic pressure, transglottic airflow and glottal resistance. MethodThe review was performed in PubMed and Web of Science databases with a time window 2000-2017. All articles reviewed obtained levelI. After performing a critical assessment of the scientific evidence, articles were classified as randomized clinical studies with experimental designs. ResultsThey are delivered from the association of aerodynamic measurements with six categories of analysis: a)as an objective method for clinical evaluation; b)studies with professional singing and speaking voice users; c)clinical and research implementations in functional laryngeal pathologies; d)research in different age groups; e)studies in canine larynx; and f)studies in voice exercises with semi-occluded vocal tract. ConclusionsThe objectivity of implementing aerodynamic measures in pathological and professional voice studies is demonstrated; the aerodynamic measures of phonation can be applied in the pediatric population, as well as in adults and the elderly.
