The treatment of late cases with stenosis of the larynx and upper trachea is complicated because of the complex situation of this portion.
Although various methods have been proposed by many physicians, most of them require multiple operations to reconstruct an adequate airpassage. It also requires a long period with perseverance of both patients and doctors to complete the procedure.
Since my subject of this symposium is to report reconstructive surgery of the airpassage, representative methods which consist of multi-stage operations were reviewed and then our one stage operation method was presented.
Multi-stage operation is combination of the following techniques:
I. Reconstruction of the framework; by scar tissue, cartilage transplantation, bone transplantation, or artificial materials.
II. Reconstruction of the inner lining; by mucosa transplantation (free or pedicle), or skin transplantation (free or pedicle).
III. Insertion of a stent; metal, rubber, acrylic resin, silicone, etc.
Technique of our one stage operation is as follow:
First, the scar tissue of the stenotic area is resected. To reconstruct the lining of the lumen, the skin pedicle flap from the cervical region is inserted and to reconstruct the framework, the costal cartilage is used. A rubber glove finger packed with silicone sponge is inserted into the newly reconstructed lumen as a stent for about four weeks. Operated site is covered directly by the skin at the surgery. The tracheostoma should remain open for about four months.
Ten cases have been treated by this method with satisfactory results.
