Acute laryngitis in children is mostly caused by viral infections and is self-limiting. However, severe cases of laryngitis can progress to third or fourth degree laryngeal obstruction, which are serious conditions requiring urgent treatment, including intubation or tracheotomy, the use of strong antibiotics, and the application of corticosteroids. Generally speaking, unless it is particularly severe or treatment is sought very late, it is very difficult to administer emergency treatment. For the most part, acute laryngitis in children is relatively easy to control and recover from. Therefore, it is very important to seek medical attention early and receive timely and correct treatment to avoid missing the opportunity for emergency intervention, which could lead to lifelong regrets.
