[Thoracic wall reconstruction using autologous skin flaps and lyophilized dura: a comparative long-term study in dogs].

In an experimental study in dogs a defect in the chestwall was created by resecting two ribs on each side. The defect then was replaced by lyophilized dura and free dermis transplants. In X-ray observations and tissue examinations both materials are evaluated by comparing the results. After one year both graft materials showed identical results concerning function and tissue compatibility. Both, dura and dermis were totally resorbed replaced by collagen and connective tissue.
