Background:
The aim of this study is to introduce the efficacy of our 3D printer custom made pressure adjustable clips for preventing keloid recurrence after ear keloid surgical excision. Mechanical pressure is increasingly applied as a means to prevent or treat keloid scars.
Methods:
10 patients were included in the study, and were treated for six months with the 3D custom printed pressure clips after ear keloid excision surgery. The mean follow-up was one year. The primary outcome assessed was the degree of recurrence of keloids, with patient satisfaction as the secondary outcome assessed by subjective history.
Results:
Keloid scars were reduced in the treated patient group. Patient scarring was decreased. There were no negative side effects observed after the therapy.
Conclusion:
Our 3d printed custom pressure-adjustable earclip model is an effective tool in the prevention of ear keloid recurrence and is associated with high patient satisfaction. The benefits should prompt further study on its value as an adjuvant therapy to surgery in keloid treatment.
Level Of Evidence:
Level III on the Evidence Rating Scale for Therapeutic Studies.
