Patient's question:
What are the symptoms of incomplete development of the infant's hyoid bone?Doctor's answer:
Infant laryngeal cartilage dysplasia often refers to the softening of laryngeal cartilage, such as the weakness of the epiglottis cartilage, which can block the laryngeal inlet during inhalation; or the weakness of the faucial epiglottic fold, which can narrow the laryngeal cavity during inhalation. Both conditions can result in inspiratory stridor and inspiratory dyspnea, and the "three sign" may be observed. If the symptoms are not severe, treatment may not be necessary. Generally, by the time the child reaches 2-3 years old, the laryngeal cartilage often develops normally, and the symptoms naturally disappear. If the symptoms are severe, tracheostomy treatment may be required.
