Background: Radiation-related hypopharyngeal stenoses are considered as complications after larynx sparing therapy of hypopharyngeal or laryngeal tumors. Methods: The reported patient suffered from chondronecrosis of the cricoid after radiation of a larynx carcinoma and was treated by removing the necrotic cartilage. To prevent emerging stenosis of the hypopharynx, a customized hypopharyngeal stent was constructed on the basis of CT scan data. The Y-shaped stent was placed dorsal to the larynx, caudal to the arytenoid cartilages and remained in place without dislocation or irritation of the larynx for 8 weeks. During that time, the hypopharynx was stented, and the mucosa grew around the stent covering the complete circumference of the hypopharynx again. 18 weeks after removal of the stent, the hypopharynx did not reveal any re-stenosis. Conclusion: This customized hypopharyngeal stent is the first reported approach applied with spared larynx, which has been tolerated for a long period of time.
