Abstract
|
|
|
Background and Objectives: Free fascia flaps provide neovascularity without adding bulk and are particularly suited to serve in microvascular transfers to recipient beds carrying an epithelial lining. As such, free fascia flaps may be
useful
in
providing a mucosal lining at the interior side of the reconstructed larynx. This study examines the reliability of a composite reconstruction method using a combined vascular flap for the laryngeal defects. Materials and Methods: A
vascularized
fascial flap which was consistently present and easy to isolate was developed in dogs. Laryngeal defects were reconstructed with a combined vascular flap consisting of lateral thoracic fascia, which is also used as a transferable vascular be. A
buccal
mucosa graft was fixed on this bed to provide as an internal lining. An autogenous auricular cartilage graft, circumferentially wrapped in vascular connective tissue, was used as an external support. Results: There were no respiratory
distress,
limitation of activity, and laryngeal stenosis after the laryngeal reconstruction. Conclusion: We have maintained the positive aspects as well as improved the negative aspects of the experiment and devised a new series of experiments which
are
now in progress. The lateral thoracic fascia is used as a transferable bed with an autogenous cartilage for support. They may be a useful tool for laryngotracheal reconstruction.
