Management of Facial Second-Degree Burns with Nanocellulose-Based Dressing: A Case Series and Systematic Review

Abstract

Background: Previous studies have evaluated the effectiveness of bacterial nanocellulose (BNC) for the treatment of thermal injuries, but the synergic effect of platelet-rich plasma (PRP) with BNC-based dressing for burns still requires further investigation. Herein, we evaluated the effectiveness of BNC dressings in the management of facial burns using PRP. Methods: Patients with second-degree facial burns were treated with BNC-based wound dressings after debridement. The burn’s depth and epithelialization were evaluated by clinical assessment. Besides using the dressings, we injected PRP subcutaneously into the left hemifacial burns. The right hemiface was only treated with the dressings. Scar quality was assessed using the Patient and Observer Scar Assessment Scale (POSAS). Results: Eight patients were included with superficial second-degree burns in 75% of the cases and deep second-degree burns in 25%. Overall, dressings were placed 3.25 days after the initial insult. None of the patients presented with complications after dressing placement. Dressing changes were not required, and no further surgical management was necessary. The mean time for epithelialization was 11.4 days. During subgroup analysis, we did not find a significant difference in the epithelialization time when comparing BNC-based dressings (11.8-days) to BNC-based dressings +PRP (11-days, p = 0.429). The mean POSAS score from a patient (17 versus 12.3, p=0.242) and surgeon (13.5 versus 11.3, p=0.26) standpoint were not significantly different using BNC-based dressings versus BNC-based dressings +PRP. Conclusion: Nanocellulose-based dressings are effective to treat second-degree facial burns. It enhances re-epithelialization with optimal aesthetic outcomes with or without platelet-rich plasma.
