Particularidades da técnica fonoterapêutica de sons hiperagudos

Abstract

Subject: the high-pitched sound consists of doing exercise series, in the high falsetto registers, promoting an additional stretching of the vocal folds. Although a technique of voice therapy, is used, there are few studies describing it, what makes that the larynx modifications during its production are little known. Objective: to carry out a revision of literature, describing found related to the use of the high-pitched sounds in the clinic practice, to the anatomophysiology of its production and its effect in the vocal tract, and the indications and problems of the technique for the disorder and the perfectioning of the voice. Results: they were found reports of significant changes in the vocal tract during the production of the high-pitched sound, as the relaxation of the thyroarytenoid muscle (TA) the contraction of the cricoarytenoid muscle (CT), balance of the emission in modal register, and increase of the vocal resistance, being able to be used, with effectiveness, in cases of ventricular phonation, hyper functional dysphonia, Reinke’s edema, vocal fold paralysis. Adductor spasmodic dysphonia, as cooperater in the efficiency of the sphincters involved in the deglutition, in psychogenic cases, puberphonia and vocal warm-up. Conclusion: there are few studies exist that describe the larynx behavior during the high pitched sound and, so that this speech, language and hearing techniques is used in a more precise and objective way, it is believed that studies must be done that they aim to prove its efficacy in the clinic practice.
