Onlay patch repair of tracheobronchial rupture.

Two cases are reported of tracheobronchial repair in which a posteriorly based intercostal muscle flap was incorporated into the membranous portion of the airway to increase the diameter of the reconstruction or to relieve tension in the suture lines. This technique permits repair of a small left main bronchus without compromise to the lumen and tension-free repair of the membranous trachea.
