Brief summary

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

Detailed 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.

Interventions

DEVICEFractional Microneedling Radiofrequency

In every patient, each one of the two scars, or each side of a large scar will be assigned to fractional microneedling radiofrequency. Fractional microneedling radiofrequency parameters; Power: 6 v, Exposure time: 800 ms. Depth: 2.5 mm (using non-insulated micro-needles), Frequency: 2 Hz for 5 treatment sessions 4 weeks apart.

PROCEDUREIntralesional Steroid Injection with and without Microneedling

In every patient, each one of the two scars, or the other side of a large scar will be assigned to intralesional steroids injection, Triamcinolone acetonide will be injected in concentration 1:2 (20 mg/dl) using insulin syringe. o 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. Microneedling will be done using the same tip of the fractional microneedling radiofrequency at same depth. Patients will receive 5 treatment sessions 4 weeks apart.

MeasureTime frameDescription
Calculation of patient and observer scar assessment scale (POSAS) to assess change of hyertrophic scars6 monthsCalculation of patient and observer scar assessment scale (POSAS) before every session and one month after the last session to clinically assess change of hyertrophic scars
Photographic documentation will be performed to assess change of hypertrophic scar(s)6 monthsPhotographic documentation will be performed by obtaining digital photographs for hypertrophic scar(s) before every session and one month after the last session.
Measurement of tissue levels of both platelet derived growth factor (PDGF) & connective tissue growth factor (CTGF) to assess change of hypertrophic scars6 monthsMeasurement of tissue levels of both PDGF & CTGF to assess change of hypertrophic scars. Tissue levels of both PDGF & CTGF will be measured by PCR in biopsies obtained from the scar areas before the treatment sessions and one month after the last session
