[Tutoplast-Dura and Zenoderm-Corium implant--materials for tissue replacement. Experimental studies]

The results of experimental studies with the use of two biostatic materials: solvent-preserved human dura mater (Tutoplast-Dura--Pfrimmer-Vigo) and lyophilized porcine dermis (Zenoderm-Corium implant--Ethicon) as prosthesis of deficient, abdominal wall tissue are submitted. The studies were performed on an animal model and consisted on the evaluation of mechanical and biological qualities of the investigated materials as well as their surgical handiness and tissue tolerability. The application of knitted polyester net as a reinforcing agent for both materials was also estimated. Process of incorporation of the prosthetic material was investigated macroscopical at 3, 6 and 12 weeks after the implantation. The experimental trials revealed the usefulness of Tutoplast-Dura and Zenoderm-Corium implant in reconstructive surgery in account of their good biocompatibility and adequate, mechanical properties. It was stated that Tutoplast-Dura was characterized by remarkably better surgical handiness in comparison to Zenoderm-Corium implant. Additional mechanical reinforcement with polyester net was not necessary.
