Swelling of the larynx is essentially a symptom of certain diseases, it may be inflammatory and inflammatory. Inflammatory edema often occurs as a manifestation of various diseases of the pharynx, larynx and other organs may occur in some acute and chronic infectious diseases, when there is inflammation of the larynx, such as:
Swelling often occurs when:
burns the throat with hot food, caustic solutions, acids, alkalis after traheobronskopii.
A special type of X-rays represent edema after radiotherapy and of the neck. Noninflammatory edema of the larynx occur in some forms of heart failure, diseases of the kidneys and tagging. This category of pathological states can be classified as type angioneurotic edema anginevrotichesky.
Laryngeal edema morphologically characterized by varying degrees of exudation in the deep layers of the mucous membrane and intramuscular connective tissue. The shape and distribution of edema depends primarily on its cause and anatomical submucosal layer.
Signs of laryngeal edema depends on the degree of narrowing of the lumen of the larynx and the speed of its spread. In inflammatory edema of the epiglottis there pain when swallowing, foreign body sensation, a slight difficulty in breathing, which can grow and change in voice. These symptoms are much worse in the propagation of edema in the propagation of the mucous membrane swelling arytenoid cartilage cherpalonadgortannyh folds, the vocal folds and podskladchatogo space. In such cases, the rapid growth of edema may occur acute stenosis of the larynx, causing severe picture of choking, threatening the life of the patient.
When laryngoscope study determined swelling of affected areas in the form of the larynx or watery gel-like lumps. Epiglottis in this case resembles greatly thickened ridge, and the region arytenoid cartilages has the form of balls. Glottis edema of the mucous membrane vocal folds sharply narrows, this narrowing of the larynx and observed swelling of the mucous membrane of podskladochnoy when swelling looks like a pincushion bilateral protrusion.
In inflammatory edema observed varying degrees of jet phenomena in non-inflammatory - congestion is usually absent.
The first task of treatment of laryngeal edema is the restoration of external respiration.
