Use of trichloroacetic acid for closure of lesion by extensors in lobules of ears

Abstract

Introduction: The use of ear lobe extenders causes a circular defect whose closure becomes a challenge for the plastic surgeon. There are multiple techniques with mobilization of local flaps in an attempt to close and return to the natural shape of the lobe. We propose to present trichloroacetic acid (TCA) as an alternative for the correction of these lesions. Methods: A total of five patients with lesions by ear skin eyelets were selected, and 90% TCA was used to close the defects. Results: After applying the product, in the first days, there was a hyperemia around the area where the acid was applied. The frosting area was replaced by a crust, which loosened over the days, concomitantly reducing the diameter of the lesion with progressive closure of the defect. Conclusion: Although more studies are needed, the use of 90% TCA proved to be a simple and practical option for the closure of enlarged ear lobes.
