Laryngotracheal reconstruction using a Vitallium alloy miniplate.

Abstract

When stenosis of the larynx and trachea involves loss to anterior support, this is usually corrected by an autograft of costochondral cartilage or of hyoid bone anchored with suture material. This paper describes an alternative technique employing a Vitallium alloy miniplate placed anterior to the airway as a means for providing support. This is placed over a fascial or auricular cartilage graft. Together, they provide a smooth scaffold for mucosal migration. Thirteen patients were treated at Indiana University Medical Center between 1991 and 1993 by means of this technique. Ten of the 13 patients (77%) achieved an adequate airway to allow decannulation. There have been no significant complications related to the use of the miniplate, and specifically, there have been no instances of infection or extrusion. It has been unnecessary to remove any of the miniplates. The Vitallium alloy miniplate offers unique advantages in laryngotracheal reconstruction in that it not only accurately approximates tissues, but it also provides external support to the airway.
