Dysphonia is a disorder characterised by an alteration of the timbre of the voice (difficulty in speaking) which can be due to various organic or functional causes of the larynx and vocal cords. When it occurs in children, it can come from neurological disorders, malformations of the larynx, laryngeal papillomatosis caused by viral infections, or from the voice being overly strained. The latter is the most common cause of dysphonia in adults, and that an untreated hyperfunction voice can produce other pathologies such as nodules or polyps on the vocal cords. In addition, other factors that can trigger dysphonia: gastro reflux, smoking, infections such as laryngitis or tuberculosis, neurological disorders or tumours of the larynx.
