title: Treatment of long, rigid tracheal stenoses. An experimental study on animals.
abstract: Using both PVC models and animal experiments, new surgical methods of expanding long, rigid tracheal stenoses were investigated. After making a longitudinal incision laterally, oval-shaped composite grafts from the auricle were sutured on either side of the trachea. The stenoses were successfully stretched from about 35 to about 80% of the original lumina. In this way, and together with a sleeve resection, stenoses up to 7 or 8 cm are operable. It is the first time in experiments that a stenosis was carried out beforehand, and later expanded. This method allows a better judgement of the final result to be reached. Modifications of the basic technique are described and results are discussed in some detail.
