The Bridging Effect of Artificial Dermis on Reconstruction of Skin Avulsion Injury

Abstract

Skin avulsion wounds are expected to be swollen and tense after trauma, and skin perfusion can be compromised after primary closure, resulting in wound dehiscence and poor healing. The artificial dermis (AD) serves as a dermal regeneration template that is used to heal skin defects with secondary intention. Therefore, the aim of this study is to evaluate the effect of AD application on traumatic skin avulsion injuries compared to conventional primary closure. A retrospective cohort of 20 patients with skin avulsion injuries were included the study: ten patients were treated with AD and ten patients were managed with primary closure. When compared to the primary closure group, AD group had a shorter average healing time (58.40 ± 26.94 days V 65.50 ± 46.45 days) and significantly higher flap viability (92.00 ± 13.17% V 78.00 ± 13.98%; p = .03). In conclusion, AD is a promising material for the treatment of skin avulsion injury and produces better clinical results.
