Background:
The treatment of long-segment tracheal stenosis is a biological and surgical problem. The introduction of preserved allografts established new possibilities for functional tracheal reconstruction.
Patients And Methods:
Since 1979 preserved allografts were used in 112 patients (including 20 children) with tracheal stenosis. Increasing knowledge in preservation, surgical treatment and pathohistology were put into practice.
Results:
Implantation of the preserved allografts into the infrahyoid muscles proved to be advantageous. Preservation with the tutoplast method prevented the risk of viral infection, and led to faster and trouble-free post-operative healing. Pathohistological studies let to improve surgical techniques by increasing the knowledge of the nature of tracheal stenosis.
Conclusion:
Functional tracheal reconstruction for long-segment tracheal stenosis can be achieved by implantation of preserved allografts.
