Novel Hyoid Reconstruction and Tracheal Onlay Grafting in a Child with Teratoma and Absence of Hyoid

Abstract

Herein is presented a case of a 3‐year‐old who was the product of a pregnancy complicated by fetal congenital cervical teratoma. The teratoma was resected day‐of‐life 6, and he underwent tracheotomy. Radiologic review of his cartilaginous cervical anatomy in utero, pre‐ and post‐tumor excision indicated congenital absence of the hyoid. An initial double‐staged laryngotracheal reconstruction improved the subglottic and tracheal airway, but the supraglottic and pharyngeal airway remained collapsed. Using a cadaveric cartilage, a hyoid was fashioned. After the pharynx and straps muscles were sewn to the hyoid construct, the supraglottic and supra‐laryngeal airway improved. Subsequent laryngotracheal reconstruction, which included tracheal onlay grafts of cadaveric cartilage, achieved decannulation. Laryngoscope, 2024
