Management of ear keloids using custom-molded pressure clips: a preliminary study

Background

The application of mechanical pressure by compression devices has gained popularity in the treatment of keloid scars. In this present study, we analyze the long-term efficacy of our custom-molded pressure clip for ear keloids. Our secondary objective is to identify risk factors for the failure of the treatment in the group of the recurrence.

Methods

The patient group consisted of 9 men and 19 women with a mean age of 27 years and a mean follow-up of 8.5 years. For evaluation of the scars, scoring ratings, Patient and Observer Scar Assessment Scale (POSAS), and SF8-questionnaire have been used.

Results

Follow-up observations showed that 71 % were treated successfully. There were significant differences in the Fitzpatrick scale, cause of the ear keloids, overall opinion, and openness for re-treatment between the recurrence and nonrecurrence group. Furthermore, treatment with our custom-molded pressure ear clip resulted in a statistically significant improvement of all the item scores of the POSAS in both the patient and observer scales. Severe complications such as infections or necrosis were not noted.

Conclusions

In this study, we show that the results of adjuvant pressure therapy with our custom-molded ear clips are comparable with the recurrence rates of other studies recently published. The strength of this study is the long follow-up. Level of Evidence: Level III, therapeutic study
