2 year baby with congenital chondrom in trachea at the height of cricoib cartilage was reported.
Since his birth, the parents noticed that he was suffered from stridor. And, one day when he was 2 year old, he was attacked by sudden dyspnea.
Under the X-ray examination and direct laryngoscopical examination, we could diagnose his case as chondrom which was grown inside of trachea at the height of cricoid cartilage.
After the tracheotomy, removals of this chondrom was performed under the vertical incision on the cricoid cartilage.
Histolological examination of the removed specimens was shown to be hyaline chondrom which originated from cricoid cartilage.
We succeeded in the complete closing of incised part of the cricoid cartilage. And, after one and half year, we could also get the permanent cicsure of his tracheostoma.
