When stenosis of the larynx and trachea involves loss of 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. |
