Brief summary

The goal of this clinical trial is to learn about the efficacy and safety of microneedling-assisted 5-fluorouracil delivery in comparison with intralesional 5-fluorouracil, intralesional corticosteroid, and microneedling with saline for the treatment of pathological scars.

Detailed description

Hypertrophic scars and keloids are dermal fibroproliferative disorders unique to humans. They are common and usually occur following burns, trauma, inflammation, or surgery, but sometimes occur spontaneously. Despite an array of therapeutic approaches for scar therapy such as surgical excision, occlusive dressings, topical and intralesional corticosteroids, interferon, cryosurgery, radiation, pressure therapy, laser therapy, retinoic acid, and silicone gel sheeting, no single method provides complete benefit. For this reason, the medical care of HTSs and keloids remains clinically challenging. The study was conducted on 60 patients complaining of HTSs & keloids.

Interventions

Undiluted 5-FU was applied topically after microneedling

undiluted 5-fluorouracil was applied topically

Triamcinolone acetonide was administered intralesionally

PROCEDUREMicroneedling With saline

saline was applied after microneedling

Masking description

The outcomes assessor will be blinded to the treatment allocation to reduce assessment bias during evaluation of scar improvement.

Intervention model description

Participants were assigned to one of four parallel treatment groups to compare the efficacy and safety of microneedling with 5-fluorouracil, intralesional 5-fluorouracil, intralesional corticosteroids, and Microneedling with normal saline as a control group in the treatment of hypertrophic scars and keloids

Design outcomes

Primary

MeasureTime frameDescription
Vancouver Scar Scale3 weeksTo detect the Change in scar severity assessed by the Vancouver Scar Scale based on four scar characteristics (vascularity 0-3, pliability 0-5, height 0-3, pigmentation 0-2) with the minimum total score 0 (normal) and the maximum total score 13 (most severe scar). Higher scores after treatment mean worse outcome.
ImageJ Analysis3 weeksTo objectively assess scar surface area. To quantify treatment effect, the percentage of change in scar area was calculated for each patient using the formula: ■("Percentage of change=" ("Post treatment area - Baseline area" /"Baseline area" )"×100" ), Higher scores mean worse outcomes.

Secondary

MeasureTime frameDescription
Patient's satisfaction score3 weeksgrade 0 (No satisfaction), grade I (poor less than 25%), grade II (fair 25-50%), grade III (Good 51-75%) and grade IV (Excellent 76-100%). The minimum total score 0 and the maximum total score 100. The higher scores mean a better outcome
visual analogue scale3 weeksto assess pain and pruritus. The minimum score is 0 indicated no pain or itching and the maximum score 10 represented the most severe pain or itching. The higher score mean a worse outcome
