The use of biological membranes in wound dressings has increasingly become a reality. Accordingly, an ideal means of preservation is sought that can provide tissue maintenance for long periods without interfering with its quality or clinical applicability. Therefore, the objective of the present study was to evaluate and histologically and microbiologically compare frog skins subjected to two different preservation methods. Sixteen frog skins were evaluated and, depending on the preservation method, subdivided into two groups with eight skins each, namely, the Freezing Group, in which the skins were frozen at -4º in a 20% glycerin solution; and the Glycerin Group, whose skins were kept in 98% glycerin at room temperature (average of 28 ºC and average humidity of 78%). The skins were analyzed fresh (T0) and at 30 (T1), 60 (T2), 90 (T3), and 120 (T4) days of preservation. Data were analyzed comparatively. There was no bacterial or fungal growth, and the skin structure and collagen arrangement remained intact at all time points in both treatments. In conclusion, both preservation methods are efficient and capable of maintaining the tissue morphological structure and preventing the growth and proliferation of contaminants for up to 120 days.
