Whether or not congenital laryngeal stridor will heal on its own depends on the cause and severity of the symptoms and cannot be generalized. If it is due to laryngeal cartilage dysplasia and the symptoms are mild, it may resolve spontaneously; if it is due to other causes, it usually does not resolve spontaneously. Congenital laryngeal stridor is an inspiratory laryngeal stridor that occurs in infants after birth. It is a symptom caused by laryngeal obstruction, and in severe cases, it may be accompanied by the triple concavity sign (the suprasternal fossa, supraclavicular fossa, and subglottic concavity during inhalation), which is mostly caused by congenital laryngeal cartilage cartilage softness, and it may also be caused by congenital webbing of the larynx, congenital laryngeal cysts, and congenital laryngeal clefts. Usually, congenital laryngeal stridor caused by laryngeal cartilage insufficiency, if the child’s symptoms are mild, without obvious breathing difficulties, do not have to rush to deal with, can first closely observe the condition, give adequate and reasonable nutrition, and wait for its gradual development and growth to 2 years of age, the symptom can be eliminated by itself and self-cure. However, children with severe symptoms, such as respiratory distress, are usually not cured by themselves and need to seek medical treatment. Other causes of congenital laryngeal stridor, such as congenital laryngeal webbing, congenital laryngeal cysts, congenital laryngeal clefts, etc., usually have more severe symptoms, affecting the quality of life of the child, and cannot be cured on their own. Children with congenital laryngeal stridor should seek prompt medical attention from the doctor to identify the cause of the disease and then undergo targeted treatment, and parents should pay more attention to the care of their children on a daily basis.
