Laryngeal cartilage dysplasia

Choking due to laryngeal cartilage hypoplasia is generally caused by premature birth or calcium deficiency and developmental dysplasia. The fontanelle of an infant usually closes at 12-18 months. Too early or too late fontanelle closure is abnormal. If a child feeds too quickly and has laryngeal cartilage hypoplasia, choking will occur. You can supplement your child with calcium and vitamin AD at the same time, and going outside to bask in the sun more often can promote calcium absorption.

Question 1: Because the child's laryngeal cartilage is not well developed, his (her) laryngeal cartilage covers the glottis when inhaling, and he (she) will make a chick-like sound. This is called congenital laryngeal stridor. Congenital laryngeal stridor is caused by the laryngeal tissue being weak and relaxed in infants and young children, which collapses during inhalation and causes the laryngeal cavity to become smaller. It is also called laryngeal cartilage softening. It often occurs shortly after birth or a few months after birth. According to the history of laryngeal stridor shortly after birth, there is no history and physical signs of foreign bodies in the respiratory tract or other diseases. The lateral laryngeal X-ray is normal, the cry is loud and the swallowing is good. Generally, direct laryngoscopy is not required to make a diagnosis.

If the symptoms are not severe, congenital laryngitis can usually heal itself by the age of 2 to 3 years. Usually, you should pay attention to prevent cold and fright to avoid respiratory tract infection and laryngeal spasm, which will aggravate laryngeal obstruction. You can adjust the baby's body position, and taking the side-lying position can alleviate the symptoms. Occasionally, those with severe laryngeal obstruction need tracheotomy. Acute laryngitis can easily cause breathing difficulties, so you should pay special attention. Strengthening calcium supplementation may have a certain effect, but cartilage softening is not caused by calcium deficiency. Although the cause is still unclear, it can be relieved intermittently. Most of the symptoms gradually improve or disappear with age. This situation is common in clinical practice. You should pay attention to prevent your baby from catching a cold and avoid choking when the baby sucks too quickly. If the baby's inspiratory breathing difficulties are severe, you can let the baby choose the side-lying position. Most babies heal themselves around 1 year old. If the symptoms do not ease, you should consider surgical treatment.

If a child has laryngeal cartilage underdevelopment, he or she should be given calcium supplements and cod liver oil in time. Another thing is that you should get more sun exposure. Give your child calcium with Xiao Xiao Jia plus calcium. Supplement it for two weeks and observe. An occasional cough is not a big deal.
