Three cases of laryngotracheal stenosis were treated by a staged operation called the 'trough method' in our hospital. After removing the stenotic tissues in the inner space, a trough was created. A composite auricular cartilaginous graft with overlying skin was used for the closure of the trough. First, the graft was embedded beneath the skin near the trough, with the skin graft facing the inner space of the trough. About 2 weeks later, the embedded grafts were slid over the trough. Using this procedure, the trough was closed and a firm framework could be reformed. This method has an advantage for the survival of the graft, and makes framework reconstruction safely.
