This canine study examines the structural stability of extensive laryngotracheal reconstruction with the sternohyoid myocutaneous rotary door flap (RDF) and modifications of the RDF with subdermal collagen and collagen hydroxyapatite matrix. The postre‐construction stability of the RDF and these modifications were tested and compared by measuring immediate postmortem airway stability during application of negative intraluminal pressures. Comparisons between controls and experimental specimens demonstrated that the RDF provides structural stability to secure airway patency under physiologic pressures. Biocompatible matrix adds further structural support in maintenance of the reconstructed lumen. This study validates that the RDF provides adequate rigid support for extensive laryngotracheal reconstruction without the requirement of skeletal support.
