Treatment of chronic laryngitis necessarily includes the elimination of all harmful factors contributing to the development of this disease, especially overvoltage of the vocal apparatus. It is necessary to sanitize foci of infection in the upper and lower respiratory tract. If there is difficulty in nasal breathing, it is necessary to normalize it.
Patients with chronic catarrhal and diffuse hypertrophic laryngitis are prescribed astringent and cauterizing substances capable of reducing the volume of tissues, reducing the secretion of glands (larynx 1-2% of an oily solution of menthol, lubrication of the mucous membrane of the larynx by 1-3% lapis, 2-3% solution of collargol or protargol, 2-3% solution of tannin on glycerol). Widely used inhalation therapy.
Patients with limited forms of chronic hypertrophic laryngitis are treated surgically. This applies mainly to the Reinke's Edema and the nodules of the vocal folds. Microsurgical endolaryngeal intervention is performed to remove hyperplastic sites of the mucosa.
It is rather difficult to treat patients with pachydermia and leukoplakia. It should be aimed at removing inflammatory phenomena in the larynx and eliminating the mechanical obstruction of the closure of the vocal folds (expectorants, inhalation therapy with chymotrypsin, trypsin, chymopsin). These drugs dilute the thick astringent mucus well and at the same time stimulate the mobile function of the ciliated epithelium, have an anti-edematous and anti-inflammatory effect. When a combination of proteolytic enzymes with antibiotics, corticosteroids and vitamins, the therapeutic effect occurs more quickly.
Electrophysiotherapeutic procedures for patients with hyperplastic laryngitis should not be prescribed in order to avoid the development of cancer.
In atrophic forms, in addition to pulverization with a weak saline or alkaline solution, infusion into the larynx of Lugol's solution, preparations of eucalyptus, chlorobutanol hydrate is used. It is advisable to use proteolytic enzymes for inhalation therapy or infusion into the larynx (10 mg of the drug dissolved in 5 ml of isotonic sodium chloride solution is used for one inhalation), it is possible to use 100 mg of lysozyme per procedure.
In the prevention of chronic laryngitis, timely treatment of chronic diseases of the nose and paranasal sinuses, chronic tonsillitis, tracheitis, bronchitis is of great importance.
Prevention and treatment of professional laryngitis primarily associated with the removal of harmful factors of production. Great attention is paid to the implementation of preventive inhalation procedures directly in the workplace. For workers in the underground professions of the coal and mining industries, ultraviolet irradiation is of great importance.
The basis for the prevention of chronic diseases of the larynx is the medical examination of the population. When taking work related to harmfulness, it must be remembered that difficult nasal breathing, frequent catarrh of the upper respiratory tract, sore throats, acute laryngitis should be considered a contraindication.
