【 摘 要 】

Reverse phonation is the voice production during inspiration, accomplished spontaneously in situations such as when a person sighs. AIM: to do a literature review, describing discoveries related to the use of the reverse phonation in the clinical practice, the anatomy and physiology of its production and its effects in vocal treatments; and moreover, indications and problems of the technique for speech disorders treatment and voice enhancement. RESULTS: there were reports of significant changes in vocal treatment during with the use of reverse phonation: ventricular distention, ventricular folds separation, increase in the fundamental frequency, mucous wave inverse movement; and it also facilitates the dynamic study of the larynx when associated with endoscopy, making it possible to have a better definition of lesion localization in vocal folds superficial lamina propria layers. CONCLUSION: There are few studies describing larynx behavior during reverse phonation and, for this technique to be used in a more precise and objective way, more studies are necessary in order to prove its effectiveness in practical matters.
