clinique<\/strong><\/h2>\n\n<p class=\"wp-block-paragraph\">Cliniquement, la dysphonie se manifeste par une modification du son habituel de la voix\u00a0: elle peut devenir faible, fatigu\u00e9e, tremblante, rauque ou rugueuse. Cela s&rsquo;accompagne souvent d&rsquo;une fatigue rapide lors des conversations et d&rsquo;une sensation de g\u00eane dans la gorge.<\/p>\n\n<p class=\"wp-block-paragraph\">L&rsquo;examen de r\u00e9f\u00e9rence pour le diagnostic est la laryngoscopie (ou vid\u00e9olaryngostroboscopie), l&rsquo;examen du larynx et des cordes vocales \u00e0 l&rsquo;aide d&rsquo;un endoscope. Celle-ci permet de visualiser les changements structurels et d&rsquo;\u00e9valuer la fonction vibratoire des plis.<\/p>\n\n<p class=\"wp-block-paragraph\">Toute dysphonie qui persiste pendant plus de deux ou trois semaines, en particulier chez les fumeurs, n\u00e9cessite un examen obligatoire par un oto-rhino-laryngologiste afin d&rsquo;exclure les maladies oncologiques. Le traitement d\u00e9pend enti\u00e8rement de la cause. Il peut inclure un repos vocal, des m\u00e9dicaments, des s\u00e9ances avec un orthophoniste (th\u00e9rapie vocale) ou une intervention chirurgicale.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>La dysphonie est un trouble qualitatif de la voix qui modifie sa intensit\u00e9, son volume, son timbre ou sa clart\u00e9.
