Effect of preservation on the physical and chemical properties of the temporal fascia.

ABSTRACT

OBJECTIVE: The temporal fascia has been widely used in tympanoplasty. In addition, the preserved fascia has been also used in the ear surgery. In this study, we planned the experiments to determine whether physical and chemical properties of the fascia preserved at a low temperature. METHODS: Preserved temporal fasciae from 21 patients were used in this study. The thickness of the temporal fascia was measured under a 3D laser microscope. The tensile strength was evaluated using a tensile tester. In addition, the chemical property evaluated was the biologic antioxidative potential of samples. RESULTS: The results showed that the strength of the fascia was not affected by the retention period. The thick fascia tended to show the less tensile strength. The intensity was highest in middle-aged donors when compared to young and older donor. The antioxidative potentials did not affect the preservation. CONCLUSION: The results suggested that the preserved temporal fascia could be safely used for tympanoplasty.
