[Reverse phonation: pathological and therapeutic aspects. Study of a clinical case].

If the phenomenon of reverse voice is well known as a transitional phenomenon occurring during normal phonation, it is less known as a pathological entity. In this connection it seemed interesting to get a fix on this type of phonation. We will illustrate our discussion with one of our patients for which the reverse voice was continuously used instead of the usual blown voice. We will present all clinical and functional investigations conducted with this patient. We also focused on the particular psycho-dysfunctional context this patient was struggling with. Instrumental investigations concerning the fundamental frequency and the laryngeal aspect allowed us to find the same results as the literature ones. We will then talk about speech therapy, its difficulties and the means proposed to patient in order for him to accept his blown exhalation voice.
