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.
目的
颞筋膜在鼓室成形术中得到了广泛应用。此外，保存的筋膜也被用于耳部手术。本研究旨在通过实验确定低温保存的筋膜的物理和化学性质。
方法
本研究使用了 21 例患者的颞筋膜。使用三维激光显微镜测量颞筋膜的厚度。使用拉力试验机评估拉伸强度。此外，还评估了样本的生物学抗氧化能力这一化学特性。
结果
结果表明，筋膜的强度不受保存时间的影响。较厚的筋膜往往拉伸强度较低。与年轻和老年供体相比，中年供体的强度最高。抗氧化能力不受保存的影响。
结论
结果表明，保存的颞筋膜可安全用于鼓室成形术。
