A Clinical Study of Infantile Stridor

We herein report 109 cases of infantile stridor treated in our department. The primary diseases diagnosed were low birth weight, cerebral palsy, and multiple malformations, however non-disorder cases were most common. Stridor was diagnosed because of swallowing disorder, laryngomalacia, and tracheomalacia, however in most cases the cause was unknown. The majority of unknown cases（28cases）were comprised infants less than 1 year of age, and only one case need tracheostomy. It is very important to detect precisely both the larynx and trachea using endoscopy. If swallowing disorder is suspected, then the swallowing function should be evaluated. If the cause of stridor is unknown, it is possible to use the wait-and-see approach without surgical intervention .
