Efficacy of custom-made pressure clips for ear keloid treatment after surgical excision

SummaryBackgroundMechanical pressure is increasingly applied as a means to prevent or treat keloid scars.AimThe aim of this study is to analyze the long-term efficacy of our custom-molded pressure-adjustable earclips to prevent keloid recurrence after surgical excision.MethodsUsing our custom-molded earclip, 88 patients who had undergone ear surgery for keloid scars were treated for 12 h a day for 6–18 months. The mean follow-up was 6.5 years. The primary outcome was the recurrence of keloids with patient satisfaction being the secondary outcome as assessed by Patient and Observer Scale (POSAS).ResultsKeloid scars did not recur in 70.5% of treated patients. The Fitzpatrick scale, which classifies human skin by type, was significantly different between the recurrence and nonrecurrence group. Differences in other patient characteristics were not found between both groups. All parameters mentioned in the POSAS patient scale drastically improved after therapy. There were no severe side effects observed after the therapy.ConclusionOur pressure-adjustable earclip model is an effective tool in the prevention of ear keloid recurrence and is associated with high patient satisfaction. Its benefits should prompt further studies on its value as an adjuvant therapy to surgery in keloid treatment.Level of evidenceLevel III on the Evidence Rating Scale for Therapeutic Studies.
