7. Needle-free jet Injector-assisted triamcinolone treatment of keloids and hypertrophic scars is effective and well tolerated in children. 180 were painful in all patients and side effects (hypopigmentation, skin atrophy, and teleangiectasia) occurred in 21% of the cases. Needle-free electronic pneumatic jet injector (EPI) technology has been developed as an alternative for conventional needle injections. The main advantages of EPI include less procedure-related pain and a tightly controlled, less operator-dependent delivery of therapeutics to the skin. This novel delivery method may be less painful, less traumatic, and also suitable for children with (extreme) needle phobia. In a recent study in adults, a significant mean reduction of 34.5% and 26.9% in respectively patient and observer scores measured by the Patient and Observer Scar Assessment Scale (POSAS) was observed.15 Furthermore, EPI-assisted injections were well tolerated and resulted in low pain scores. In this study, we aimed to investigate the effectiveness, tolerability, and patient satisfaction of EPI-assisted TCA treatment of keloids and HTS in children.
