Acute laryngitis in children is a self-healing disease, mostly caused by inflammation or injury. Controlling the inflammation or reducing the damage generally allows for self-healing. However, it is of course best to treat according to the cause during the process, eliminate the cause, and then promote the repair of the mucous membrane to achieve cure. Treatment of acute laryngitis in children generally includes symptomatic and etiological treatment. Especially, symptomatic treatment is very important, especially in reducing the severity of laryngeal obstruction.
