Laryngeal sensory dysfunction

The larynx is the functional center of the upper respiratory tract, not only in the biological but also in the social sense, which reacts delicately to violations of its innervation, endocrine functions, to various kinds of psychogenic factors, occupational and household hazards.

Laryngeal sensory dysfunction includes hyperesthesia, paresthesia, and hypoesthesia of the mucosa and submucosal structures.

Larynx angina

The term "laryngeal angina" means acute non-specific inflammation of the laryngeal tissue that is localized in the vestibular ventricles, aryepiglottic folds, inter-pile spaces, pear-shaped pockets with the development of edema and infiltration of the mucous membrane. The disease is most often caused by pathogenic strains of cocci.

Chondro-perichondritis of the larynx

The inflammatory process in the larynx can spread to the perichondrium and cartilage, as a result, the laryngeal chondro-perichondritis is developing. Chondro-perichondritis can be primary (it causes hematogenous infection) and secondary (first the mucous membrane of the larynx is affected, and then the perichondrium and cartilage).

Distinguish chondro-perichondritis and diffuse, acute and chronic. Basically, both sheets of perichondria are affected, therefore the division of chondroperi chondrite into external and internal is to some extent conditional.

Phlegmonous laryngitis

Phlegmonous laryngitis is an acute inflammation of the larynx, characterized by the proliferation of a purulent process not only in the submucosa but also in the muscles and ligaments of the larynx, sometimes the perichondrium and cartilages are involved in this process.

Etiology of phlegmonous laryngitis

The cause of the disease can be laryngeal angina, external injuries of the larynx and damage to its mucous membrane (foreign body, chemical, and thermal burns, etc.). Supercooling plays an important role in the development of the disease.

Acute laryngotracheitis in children

Acute laryngotracheitis in children develops in ARVI, is their manifestation, in effect, one of their syndromes. The problem of acute laryngotracheitis is one of the leading not only in pediatric otorhinolaryngology but also in pediatrics in general, which is caused by the high frequency and severity of the disease. So 99% of the observations of acute stenosis of the larynx in young children occur in laryngotracheitis, caused by acute respiratory viral infection.

Laryngeal dithteria

Synonyms for the term "Laryngeal diphtheria" are "diphtheria croup", or "true croup." Laryngeal diphtheria often affects young children, although the disease can occur in older children, as well as in adults.

Laryngeal diphtheria often occurs in combination with pharyngeal and nasal diphtheria, so this condition is called a downward croup. Isolated laryngeal diphtheria (primary croup) is less common.

Chronic laryngitis

Chronic laryngitis usually occurs as a result of untreated acute laryngitis. Often, its occurrence is due to pathological changes in the nose, paranasal sinuses, throat, and lower respiratory tract. Among the most frequent causes of chronic laryngitis, it is necessary to allocate increased voice load, smoking, various professional harmfulness, abuse of alcohol or food irritating the mucous membrane.
