Voice Disorder Classifications: A Scoping Review - Part A.

Voice is a complex and multidimensional phenomenon of interest to different disciplines. Divergent terminologies and, consequently, classification systems constitute, historically, a difficulty in this field of knowledge, which limits communication between professionals from different countries, backgrounds, and clinical experiences, and well as limiting clinical management and discussion of scientific research findings. This article aims to map and analyze the different diagnostic classifications in voice by describing the findings of a scoping review, consisting of both electronic and manual searches.
