Laryngitis is an inflammation of the larynx most often infectious, of viral or bacterial origin. It is frequent and most often benign.
In children, however, it can progress to a breathing difficulty potentially dangerous, because of the narrowness of their larynx.
In adults, there are also chronic irritating laryngitis due to tobacco or the misuse of his voice.
From an anatomical point of view, the larynx is located in the throat behind the tongue. You must use a laryngeal mirror (with a curved handle) to see it. There are different structures: the epiglottis, the vocal cords and the glottis.
The air we breathe then passes through the nose or mouth, the pharynx, then the larynx from the epiglottis. Then he joins the supra-glottal space, the glottis and the vocal cords. And finally, the subglottic space, the trachea, the bronchi and the lungs.
As its name suggests, laryngitis is an inflammation of the larynx. This causes swelling of the larynx likely to cause:
- a loss of voice or a hoarse voice,
- an irritating cough,
- a pain,
- sometimes a difficult breathing.
All of these signs can be associated with:
- body aches,
- other symptoms related to the cause of laryngitis.
