Level of Evidence on Platelet-rich Plasma in Plastic Surgery

Bone Graft Substitutes and Enhancement in Craniomaxillofacial Surgery

Critical-sized bone defects are a reconstructive challenge, particularly in the craniomaxillofacial (CMF) skeleton. The "gold standard" of autologous bone grafting has been the work horse of reconstruction in both congenital and acquired defects of CMF skeleton. Autologous bone has the proper balance of the protein (or organic) matrix and mineral components with no immune response. Organic and mineral adjuncts exist that offer varying degrees of osteogenic, osteoconductive, osteoinductive, and osteostimulative properties needed for treatment of critical-sized defects. In this review, we discuss the various mostly organic and mostly mineral bone graft substitutes available for autologous bone grafting. Primarily organic bone graft substitutes/enhancers, including bone morphogenic protein, platelet-rich plasma, and other growth factors, have been utilized to support de novo bone growth in setting of critical-sized bone defects. Primarily mineral options, including various calcium salt formulation (calcium sulfate/phosphate/apatite) and bioactive glasses have been long utilized for their similar composition to bone. Yet, a bone graft substitute that can supplant autologous bone grafting is still elusive. However, case-specific utilization of bone graft substitutes offers a wider array of reconstructive options.

Clinical therapeutic effects of platelet-rich plasma in patients with burn wound healing: A protocol for systematic review and meta-analysis

BACKGROUND

In clinical settings, burn wounds are frequently encountered. Since burn wounds are a form of physical injury, they can have long-term adverse effects on the human body. It has been a significant challenge to treat burn wounds completely. Since traditional treatment strategies have been unable to heal burn wounds completely, they lack the efficacy to cure the wounds without long-term effects, such as heavy scarring. Reportedly, platelet-rich plasma (PRP) has shown potential to accelerate wound healing. Yet, there are no conclusive reports on a methodological comparative study of research that has assessed the medical benefits of PRP for treating individuals carrying burn wounds. Thus, the present meta-analysis and systematic study aims to assess the medical benefits of PRP for treating patients carrying burn wounds.

METHODS

The authors will conduct a comprehensive search for randomized controlled trials that evaluate the safeness and efficiency of PRP to treat burn wounds. The search includes 3 Chinese language databases (WanFang database, Chinese BioMedical Literature database, and China National Knowledge Infrastructure) and 4 English language databases (Cochrane Library, EMBASE, Web of Science, and MEDLINE). These electronic databases will be searched from their establishment till May 2021. A pair of independent authors will be selecting eligible studies for extracting data. The same authors will employ the Cochrane risk of bias tool to evaluate the bias risk. We will make use of RevMan (version: 5.3) software to complete data synthesis.

RESULTS

The present protocol will establish practical and targeted results evaluating the efficacy and safeness of using PRP to treat burn wounds. The current study also provides a reference for clinical use of PRP.

CONCLUSION

Stronger evidence about the effectiveness and safety of using PRP to treat and heal burn wounds will be provided for clinicians to refer.
