Acute laryngitis in children can recur, similar to tonsillitis. Some children may have inherently lower immune function in the larynx, or a relative defect, which makes them prone to inflammation in the larynx whenever there is an upper respiratory infection. Therefore, we generally inform parents that if the child has a history of laryngitis, they should be aware of this condition in the future, especially of sudden respiratory difficulty at night and hoarseness. It is important to pay attention as laryngitis tends to worsen at night, and if it occurs, we recommend seeking medical attention promptly.
