About

Comparing between the effect of Fractional Microneedling Radiofrequency Versus Intralesional Steroid Injection with and without Microneedling on Tissue levels of PDGF & CTGF in Hypertrophic Scars

Full description

In each patient, each one of the two scars, or each side of a large scar will be assigned to one of the following treatment methods: 1-Fractional microneedling radiofrequency 2-Intralesional steroids injection. Scars treated with intralesional steroids will be subgrouped into two groups, one group treated with only intralesional steroids and the other group treated with intralesional steroids and followed by microneedling. Fractional microneedling radiofrequency parameters; Power: 6 v, Exposure time: 800 ms. Depth: 2.5 mm (using non-insulated micro-needles), Frequency: 2 Hz. For intralesional steroids injection, Triamcinolone acetonide will be injected in concentration 1:2 (20 mg/dl) using insulin syringe. Microneedling will be done using the same tip of the fractional microneedling radiofrequency at same depth. All patients will receive 5 treatment sessions 4 weeks apart.
