Comparison of the efficacy of Fractional Radiofrequency Microneedling alone and in combination with platelet‐rich plasma in neck rejuvenation: a clinical and optical coherence tomography study

Abstract Background Esthetic improvement of the neck and cervicomental angle remains one of the most challenging aspects of rejuvenation. Fractional radiofrequency microneedling demonstrated significant skin tightening and lifting of lower third of the face. Aim of work To evaluate and compare fractional radiofrequency microneedling alone and in combination with autologous platelet‐rich plasma (PRP) in neck rejuvenation. Methods 20 patients with mild to moderate neck laxity were randomized to receive 3 sessions of either fractional radiofrequency microneedling +PRP (group A) or fractional radiofrequency microneedling monotherapy (group B). Evaluation was done using optical coherence tomography to detect dermis thickness, measurement of cervicomental angle, a score done by two investigators blinded to used modality (GAIS) and patient satisfaction score. Results Both Groups showed a statistically significant improvement in all parameters. Comparing the two groups, the mean dermal thickness after treatment was higher in group A compared with B but was found statistically insignificant. More favorable results were reported in group A according to GAIS. Other parameters showed comparable results. Conclusion Fractional microneedle radiofrequency with insulated microneedles offers a safe and effective modality for mild to moderate neck laxity when used alone or in combination with PRP. It remains questionable whether combining fr‐RF microneedling with PRP provides more favorable results in terms of efficacy and side effects.
