[Use of standard protocols in the evaluation of voice disorders]

The purpose of this paper is to present a protocol for the use of standard forms in the evaluation of laryngeal structure and function in patients with voice disorders. The forms are designed to cover all the essential parameters needed to reach an accurate descriptive diagnosis which allows us to have an appropriate therapy plan according to the individual's detailed observations. It also gives us a consistent standardized evaluation form to measure changes after therapy whether behavioral, medical or surgical, and to compare different observations across patients. Reporting observations in this consistent manner will make characteristic patterns of different vocal behaviors readily obvious to the researcher or the clinician and reduce the possibility of missing any important details. The protocols are: indirect laryngoscopy, video-stroboscopic-evaluation form, functional voice and auditory perceptual voice evaluation.
