The causes of hoarse crying in babies mainly include acute laryngitis, vocal cord polyps or nodules, as follows: 1. Acute laryngitis: If the baby’s larynx becomes inflamed after getting cold or cross-infection, hoarse crying will occur, which is due to the vocal disorder caused by laryngeal edema. In this case, we should apply glucocorticoids for nebulized inhalation treatment, such as nebulized treatment with inhalation budesonide suspension, which is a glucocorticoid with good effect of eliminating inflammatory edema and is very suitable for acute laryngitis; 2. Vocal cord polyps or nodules: If the vocal cord has polyps or nodules, it will also cause vocal abnormalities, resulting in hoarse crying. In this case, it is necessary to go to the ENT department for surgical treatment in a timely manner.
