Composite hyoid bone graft interposition for the treatment of laryngotracheal stenosis.

INTRODUCTION Chronic laryngotracheal stenosis (LTS) remains a challenging problem for otolaryngologists. A composite hyoid bone interposition graft has the potential to be an ideal graft because the head and neck surgeon can obtain the graft in the same operative field with good vascular supply from the muscle pedicle. METHODS A composite hyoid interposition graft was used to provide structural support for the reconstructed lumen of the larynx or trachea in 2 cases of LTS. RESULTS Two patients underwent successful decannulation with acceptable laryngeal function over a long-term observation period. CONCLUSION This technique allows vascularized stable graft survival with minimal donor site morbidity. Furthermore, it can be performed for thyroid, cricoid, and tracheal stenosis without fear of damage to the recurrent laryngeal nerves.
