Abstract
BACKGROUND
Keloids and hypertrophic scars can cause severe pain, pruritus, and psychological distress. Conventional intralesional corticosteroid treatment with needle injections remains challenging, especially in children with needle phobia.
OBJECTIVE
We aimed to evaluate the effectiveness, tolerability, and patient satisfaction of intralesional treatment with triamcinolone acetonide using a needle-free electronic pneumatic jet injector in children with keloids and hypertrophic scars.
METHODS
A retrospective study was performed in children with keloids and hypertrophic scars who received intralesional triamcinolone acetonide treatments using an electronic pneumatic jet injector. Effectiveness was evaluated using the Patient and Observer Scar Assessment Scale and Global Aesthetic Improvement Score at follow-up versus baseline. Tolerability was assessed with reported adverse effects and injection-related pain using a visual analog scale. Satisfaction questionnaires were used to evaluate treatment-related patient satisfaction.
RESULTS
Six female patients and five male patients aged 5-17 years, with a total of >118 keloids or hypertrophic scars were included. Electronic pneumatic jet injector treatment led to a significant reduction in the total Patient and Observer Scar Assessment Scale observer and patient scores compared with baseline, with a median reduction of 28.9% and 23.8%, respectively (p = 0.005; p = 0.009). Median visual analog scale pain scores for electronic pneumatic jet injector treatment were significantly lower compared with needle injections, 3.0 versus 7.0, respectively (p = 0.027). No severe adverse effects were reported. Overall, 6 patients were 'satisfied' and five patients were 'very satisfied' with the treatment.
CONCLUSIONS
Electronic pneumatic jet injector-assisted intralesional triamcinolone acetonide is an effective and well-tolerated treatment for keloids and hypertrophic scars in children. It should be considered as an alternative non-traumatic delivery method, especially in children with needle phobia or severe pain during previous needle injections.
