Preparation of platelet-rich fibrin membrane over scaffold of collagen sheet, its advantages over compression method: A novel and simple technique

Abstract

Introduction: Platelet-rich fibrin (PRF) is compressed by using various tools to make platelet-rich fibrin membrane (PRFM). Preservation of platelets and plasma content of PRFM depends on the compression method used. To overcome limitations of compression method, we prepared PRFM over scaffold of collagen sheet without using any compression device. Aims and Objective: To prepare PRFM without using any compression device over a scaffold of collagen sheet and to evaluate its efficacy in chronic nonhealing ulcer. Materials and Methods: PRFM was prepared, with minor modification in Choukron's protocol, over a collagen sheet without using compression device. To study its efficacy and reproducibility, total 15 patients over 18 years of age with chronic, nonhealing ulcers of more than 3 months of various causes were included and patients with active wound infection were excluded. Results: We were able to prepare and reproduce PRFM by our technique. It overcomes the limitations of compression method with comparable efficacy to compression method. Results obtained on comparison at week 0, 3, and 6, by paired t-test, were found to be statistically significant (P 0.0001). Conclusion: Preparation of PRFM with the method described is easy and reproducible. Use of collagen sheet synergistically improved wound healing.
