Congenital hypoplasia of laryngeal cartilage is caused by calcium deficiency. It is important to supplement calcium and vitamin D to promote cartilage development. Additionally, due to the potential for respiratory difficulties, precautions should be taken to prevent colds to avoid exacerbating breathing problems. Generally, this condition will naturally heal around the age of 2. If parents are still concerned, they can bring their child to a regular children’s hospital for a check-up every three months.
