Laryngitis in children
Laryngitis in children requires accurate diagnosis and proper therapeutic treatment. There are several varieties of laryngitis, having a different etiology and symptoms, so it is important to be able to correctly determine the type of laryngitis for the purpose of appropriate therapy. Despite the success of modern medicine and a wide selection of medicines, laryngitis in children still remains in the ranks of life threatening diseases.
Laryngitis belongs to a group of disorders in which the inflammatory process covers the mucous membranes of all or parts of the larynx. Laryngitis in children younger than 4 years old, proceeds differently than in older children. According to numerous reports, laryngitis in young children, most often, but not always, develops due to the defeat of a viral infection. Some studies indicate the role of an allergic factor in the etiopathogenesis of laryngitis.
The most common cause of laryngitis in young children is parainfluenza virus. Some cases describe the development of laryngitis due to exposure to the influenza virus, rubella and the varicella-zoster virus. Epiglottitis (inflammation of the epiglottis) should be treated separately. The cause of this disease is almost always the bacterium hemophilus influenza.
Differences in the etiology and course of the disease in children of different age groups, mentioned above, occur due to specific age-related changes in the structure of the larynx. The larynx of young children is higher, and the mucosa is more viscous and contains more soft tissues. This soft tissue is located, mainly, under the mucous membrane of a scaly palate fold, in particular, in the underlay section. The special reactivity of the mucosa in young children makes them more susceptible to infections, especially to viral pathogens. Some of these infections can lead to swelling of the mucous membrane. The respiratory tract of small children on this site is relatively narrow, and the cartilaginous ring limits the size of the lining department. Therefore, the swelling of the mucous membrane in this area, can lead to severe consequences, leading, in some cases, to the syndrome of acute respiratory failure.
