Laryngitis can be treated with nebulized inhalation, which is very effective. Laryngitis is a common and frequent disease in otolaryngology, and it most commonly occurs in infants and young children. This is because the mucous membrane of the pharynx in infants and young children is relatively lax. Once their immunity and resistance decreases, bacteria or viruses can invade, leading to congestion and edema of the pharyngeal mucous membrane. It also causes the patient to develop fever and pain in the throat, predominantly pain during swallowing. Additionally, the patient may experience a barking cough, hoarse voice, and in severe cases, it can lead to breathing difficulties, suffocation, and even death. Upon examination, obvious congestion and swelling of the pharyngeal mucous membrane can be found, particularly severe on both vocal cords, with good vocal cord movement but incomplete closure. In terms of treatment, the patient first needs symptomatic anti-inflammatory treatment, and can also use nebulized inhalation to help reduce the congestion and swelling of the throat, which generally improves gradually over about a week.
