What is laryngitis
Laryngitis - inflammation of the larynx associated usually with colds or infectious diseases such as measles, scarlet fever, whooping cough. The development of the disease contribute to hypothermia, breathing through the mouth, the dusty air, Smoking and alcohol consumption, overexertion of the larynx.
Laryngitis may be short-term or long-term (chronic). Basically, the disease progresses rapidly and lasts no more than 2 weeks.
Chronic symptoms last for 2 weeks or longer. Consult your doctor if symptoms last longer than 2 weeks, because laryngitis can be caused by more serious diseases.
What triggers / Causes of Laryngitis:
Acute laryngitis occurs as an independent disease as a result of local exposure to cold or excessive strain of voice (e.g., singers, teachers), or as manifestations of common acute infections (influenza, measles, etc.). The inflammatory process can capture all or the mucous membrane of the larynx - diffuse form of laryngitis, or the mucous membrane of the epiglottis, vocal folds, walls pidholosoviy cavity.
Chronic laryngitis develops as a consequence of repeated acute laryngitis or long-term inflammatory processes in the nose and paranasal sinuses, and throat. Contribute to disease-Smoking and alcohol abuse, over-voltage voice. Chronic laryngitis often develops among teachers as a professional disease.
Pathogenesis (what happens?) during Laryngitis:
When diffuse acute laryngitis the mucous membrane looks sharply reddened; the swelling is more pronounced in the area of folds of the vestibule. Of inflammation, and hence expansion, of blood vessels can leak blood, forming on the mucous membrane of purple-red spots (more common in complicated influenza). In isolated form, acute laryngitis sudden reddening and infiltration of the mucosa can be expressed only in the epiglottis. Often acute inflammatory process covers the mucous membrane not only of the larynx, but trachea (laryngotracheitis). It is often observed coughing, usually with phlegm, produced by the mucosa of the larynx and trachea.
Symptoms Of Laryngitis:
The clinical picture of acute laryngitis is characterized by deterioration of General condition, often the temperature rises. In the blood laboratory study determined the indicators of the inflammatory process (increased number of white blood cells, accelerated ESR). When the preferential localization process in the region of the epiglottis or back of the throat may experience pain when swallowing. The voice becomes hoarse. Difficulty breathing may be caused by narrowing of the glottis due to spasm, swelling (or even development of an abscess). In acute laryngitis patients complain of a feeling of dryness, tickling, scratching in the throat; cough, initially dry, and later accompanied by expectoration of mucus; the voice becomes hoarse, rough or very silent. Sometimes there is pain on swallowing, headache and slight (to 37.4°) temperature rise. The duration of illness when medication by the doctor usually does not exceed 7-10 days.
In chronic laryngitis patients complain of hoarseness, voice fatigue, a feeling of rawness, sore throat that causes constant coughing. With exacerbation of the inflammatory process, all these phenomena are amplified.
Varieties of laryngitis
Catarrhal laryngitis is manifested by hoarseness, rawness in the throat, feeling sore, a recurring cough. Catarrhal laryngitis is the easiest form of disease.
Hypertrophic laryngitis is expressed stronger hoarseness, cough and sore. In this case, the ligaments are formed small, the size of a pinhead growths, the so-called "singer's nodules", which give the voice hoarseness. Some children suffering from laryngitis in childhood, adolescence hoarseness passes. Doctors attribute this to hormonal changes. Treatment is the same as with other types of laryngitis. In extreme cases, bumps on the ligaments cauterize with silver nitrate solution. If the ligaments are changed very much, sometimes it comes before the surgery - affected areas of the ligaments are surgically removed.
Atrophic laryngitis is manifested by thinning of the inner - mucosa of the larynx. Patients complain of dry mouth, painful cough, the voice is almost always hoarse. Severe coughing can deviate peel streaked with blood. Fortunately, in children, the disease almost never occurs. The reason for this laryngitis doctors believe overreliance on spicy food, rich in seasonings and spices. Usually, in addition to the larynx, and also affects the back of the throat. The disease is common among mountaineers, the inhabitants of the Caucasus.
There is also a special type of laryngitis, the so - called professional. This disease usually affects teachers, teachers and other people who have often to strain my voice. The cords often produced a kind of thickening - "singer's nodules". Over time, the voice becomes, like Vito Corleone from "the Godfather".
In diphtheria laryngitis caused by spread of infection from the tonsils down his throat. Mucosa covered with white membrane that can separate and cause a blockage of the airway at the level of the vocal cords. A similar membrane can be produced in streptococcal infection.
Tuberculous laryngitis usually secondary and occurs in the propagation of tuberculosis of the lungs. In tuberculous laryngitis the laryngeal tissues are formed lumpy nodules. Also perhaps the destruction of the laryngeal cartilage and the epiglottis.
Laryngitis is one of the many complications of syphilis. In the second stage of syphilis can develop ulcers and mucous plaques. In the third stage of the disease scarring which can distort the larynx and vocal cords, which can result in permanent hoarseness.
