Children with prolonged hoarseness are likely to suffer from hypertrophic laryngitis, which is usually caused by prolonged speech or vocal practice that leads to vocal fold hyperplasia and thickening, and sometimes the child is also prone to vocal nodules, which usually occur in the symmetrical position of the bilateral vocal folds and lead to hoarseness due to the lack of closure of the vocal folds. Sometimes when the child cries or speaks for a long time, the symptoms of hoarseness will be more obvious. Treatment: Conservative treatment with medication, such as Huang’s Voice Pills or Golden Voice Pills, etc. Monthly follow-ups are needed to observe the recovery of the voice, and fiberoptic laryngoscopy can be done to clarify the specific condition of the child’s vocal cords, and it is recommended that the child rests with proper vocal rest.
