Children like to shout, cry and move around with colds and coughs, which often leads to hoarseness. According to the parents, this is not a big deal and can be taken care of. But often, a single thought may cause the child’s voice to never return to its previous crispness. The three or four years old is the age group with a high incidence of hoarseness, on the one hand, because children often shout in kindergarten, the vocal cords stimulation is more powerful, on the other hand, also related to the special anatomical structure of the pharynx. “The larynx of children is narrow and rich in lymphatic tissues, so once the voice is overused or the upper respiratory tract is infected, it can easily cause lymphatic tissue congestion and edema, and cause inflammation and damage to the vocal cords. If you pay attention to resting your voice, you can usually recover quickly, but the problem is that children do not have self-control and do not protect themselves, and parents think that this is a small thing, after a few days can naturally be good, so time so delayed that the acute damage may become chronic. “Inflammation lasts for more than three months, usually the vocal cords will thicken, if this time is not treated, it will gradually form vocal cord nodules, serious may have to do surgery”. To prevent damage to the vocal cords, parents should usually teach their children to protect their voices, not to always shout, and not to ignore a child’s cold and cough. If the symptoms of hoarseness appear, you should go to the ENT department as soon as possible to seek treatment for the cause. If it is caused by cold and cough or acute inflammation, treat the cold and eliminate phlegm; if it is caused by shouting and improper use of voice, correct the habit of speaking and train the child to pronounce the words correctly; if it is caused by source diseases, such as tonsillar hypertrophy, adenoid hypertrophy and rhinosinusitis, treat the cause and deal with acute laryngitis as a matter of urgency to avoid breathing difficulties caused by laryngeal edema; and some are caused by congenital Some of them are caused by congenital vocal fold deformities, which eventually need surgery or specialist treatment. The earlier the treatment, the faster the recovery. However, in clinical practice, most children suffer from hoarseness due to improper use of voice, so in addition to teaching children to pronounce words correctly and not to speak in a noisy environment, they must also undergo voice training under the guidance of a specialist. This is a time-consuming process and both parents and children need to be patient. Parents, especially, should not be nervous and scold their children in anger when they see that they are not cooperating with the treatment. It is better to guide them gently, either by satisfying their children’s requests appropriately or by distracting them so that they will stop shouting or crying. During the treatment period, it is also important to avoid spicy and stimulating foods in the diet. With some persistence, the vocal cords will slowly return to normal. Even if vocal cord nodules are already present, there can be significant improvement with conservative treatment.
