What are the common symptoms of acute laryngitis in children? The symptoms of acute laryngitis in children are also relatively obvious, but because this disease is very harmful and has many similarities with the symptoms of many throat diseases, it is important to understand the symptoms of this disease and make timely and correct judgments. So what are the common symptoms of acute laryngitis in children?

What are the causes of acute laryngitis?

The main "target" of acute laryngitis in children is children aged 6 months to 3 years old. It is an acute inflammation of the laryngeal mucosa mainly in the glottis area. Chinese medicine also calls it "laryngeal wind, laryngeal sound, laryngeal paralysis", etc. It is not only a common and dangerous respiratory disease in children, but also often occurs in combination with the larynx, trachea, and pneumonia.

Acute laryngitis in children is mainly caused by colds or upper respiratory tract diseases, especially in winter. Why does this disease come more fiercely in winter?

Experts say that in cold seasons, the weather changes quickly, the temperature difference between morning and evening is large, the air is dry, and the air circulation is poor, which makes it easy for bacteria and viruses to multiply. When children's resistance is reduced due to cold, fatigue, etc., they are prone to infection with viruses or bacteria and develop symptoms of acute laryngitis. At the same time, the anatomical and physiological characteristics of children's throats also make it difficult for children to resist the invasion of diseases.

1. The laryngeal cavity of children is narrow, and the cross-sectional area of ​​the glottis and subglottis is many times smaller than that of adults. Once the laryngeal mucosa swells due to inflammation, the laryngeal cavity will be significantly narrowed, resulting in breathing difficulties. Children have abundant laryngeal mucosal lymphatic vessels and glandular tissue, not only because of abundant mucosal lymphatic vessels, but also because the submucosal tissue is relatively loose. Therefore, when they suffer from inflammation, the swelling is very serious.

2. The laryngeal cartilage of children is relatively soft, resulting in weak supporting force. When the larynx is narrowed due to inflammation, during the inhalation phase, the negative pressure in the child's chest cavity, trachea and larynx increases, causing the laryngeal cartilage to sink to the middle and the laryngeal cavity to become narrower.

3. Children's laryngeal nerves are relatively sensitive, and stimulation can easily cause laryngeal muscle spasms and laryngeal stenosis.

4. Children have weak coughing function and often do not know how to cough, which makes it difficult to expel secretions in the throat and trachea, thus causing laryngeal spasm and laryngeal obstruction.
