Avaliação da reparação da musculatura abdominal de coelhos com o implante de cartilagem auricular suína.

Abstract

Surgeons from all medical fields have been challenged in the search for a suitable surgical technique for repair of muscle or organs defects and, therefore, the use of organic biomaterials advantages were seen, in view of its power attenuating the tensile strength and act for a long period while maintaining the asepsis of the material still being inexpensive and easy to handle. The porcine articular cartilage is among the vast number of biological tissues that can be used as organic biomaterial, which is devoid of vascularization has low cellularity and toxicity, and thus are resistant to infection, healing and pathologically affected tissues and capable of forming according to the application site. The scope of this study is to evaluate clinically and histologically the repair of rabbit muscle with the implementation of swine auricular cartilage preserved in glycerin. For this 18 rabbits were used in which were surgically created two wounds in the abdominal muscles. In one of the wounds was held just myorrafy (Control group - CoG) and other wound beyond myorrafy was implanted on this one swine auricular cartilage preserved in glycerin (Cartilage group - CaG). The animals were divided into three time points: three, seven, and eleven postoperative days, with six animals in each. The clinical and histopathologic analysis revealed adherence of omentum with the main muscles in the suture region, without signs of reaction or failure of both scar tissue on swine auricular cartilage at all times evaluation. The histological results confirmed the incorporation of the prosthesis to the biological receptor site without evidence of complications, with inflammatory reaction in booth groups, more intense in CaG. It was concluded that the swine auricular cartilage may be used in the repair of muscle and does not cause adverse reactions.
