[Chemical preserved human trachea as prosthesis in covering tracheal defects--first experiences (author's transl)].
Basing upon animal experiments at the first time in two cases parts of a chemically conserved trachea were used for closing tracheal defects in reconstructive procedures. After layering a silastic foil on mucosal surface of the conservated tracheal piece in a first step this prepared transplant is implanted beneath the tracheal defect subcutaneously. Hitherto after 2 vs 3 months in a second step the paratracheal preimplants, now vascularized, were turned about the defect like a pedicle flap. Both transplants healed in the tracheal defect without disturbances. The new inner surface of the trachea now after an observation up to 6 months has remained plain without any granulations.
