Stridor congenita is a peculiar disease of early age, characterized by inspiratory noise during breathing.
Stridor traditionally begins immediately or soon after birth, decreases in the second half of the year and is cured by itself by 2-3 years. The basis of this disease, according to most authors, is an anomaly in the development of the outer ring of the larynx, arytenoid cartilages. The epiglottis is soft and folded into a tube. The aryepiglottic ligaments are close to each other and form, as it were, loose sails, which, when inhaled, vibrate, forming noise.
The noise is whistling, sonorous, reminiscent of the cooing of pigeons, sometimes the purring of a cat, the cackling of a chicken. The intensity of the noise is reduced during sleep, when the baby is transferred from a cold to a warm room, if the child is calm. On the contrary, it increases with excitement, crying, coughing. The general condition of the baby with stridor is slightly disturbed, breathing is slightly difficult, sucking is normal, the voice is preserved.
Stridor can be inspiratory or expiratory. When a baby has stridor, you need to find out if there is a significant increase in the thymus gland, bronchoadenitis, congenital heart disease or mediastinal tumors, which can cause compression and a change in the nature of breathing. In severe forms of stridor, it is advisable to conduct a laryngoscopy examination to determine whether the stridor is caused by a polyp or an innate membrane of the vocal cords. It is also necessary to remember the retropharyngeal or retrotonsillar abscess as the cause of stridor breathing.
The phenomena of stridor traditionally decrease by 6 months of life and disappear completely by 2-3 years. Treatment is not carried out.
