Dysphonia is a very common voice disorder, but it is often underestimated. It affects the proper functioning of the vocal cords in one in thirteen people in Spain, although this proportion increases in certain professions. This is the case for teachers, since the voice is an essential tool in their daily work, and more than half suffer some type of disorder throughout the school year. In fact, the Spanish Society of Otorhinolaryngology and Neck and Spine Surgery (SEORL-CCC) estimates that almost nine out of ten preschool teachers will experience dysphonia during their professional career, which is why experts emphasize prevention and early treatment to avoid long-term complications.
