Abstract

Conservation laryngeal surgery has been limited by difficulties with partial resection of the cricoid. Numerous options have been suggested that include temporoparietal flaps, free cartilage grafts, radial forearm free tissue transfers, and tracheal autotransplantation with vascular carriers. The authors present a one-stage procedure for the reconstruction of the cricoid cartilage based on the thoracodorsal artery scapular tip (Tdast) autogenous transplant that uses the curved tip of the scapula and does not create a secondary tracheal defect. Because the Tdast is a vascularized graft it may withstand radiation treatment.
