Morphological Approach to the Study of the Dynamics of Changes in the Fibrous Structures of the Dermis in Dermotension

Abstract

Background: The method of dermotension is successfully used in surgical practice to close extensive defects or as a result of treating fractures using the Ilizarov apparatus. However, to obtain the desired result, surgeons often neglect the condition of the skin flap itself. In this regard, the purpose of our study was to study the dynamics of changes in fibrous structures in the dermis of the skin during dermotension. Methods and Results: The material for the 14-day study was a skin flap of Wistar rats obtained after distraction with the Ilizarov apparatus. Analyzing the morphological picture of the state of the dermis after the study, we found a decrease in the thickness of both the epidermis and the dermis by 2.3 and 3.3 times, respectively. A decrease in the density of collagen structures of both types I and III was also noted. Conclusion: The results obtained indicate the restructuring, first of all, of the fibrous component of the dermis, which consists in reparative-restorative processes, which must be taken into account when choosing the rate and duration of dermotension.
