Abstract:
BACKGROUND: Keloids are dense, fibrous tumors that arise from the dysregulation of normal wound healing, ultimately outgrowing the initial traumatic lesion. OBJECTIVE: We present a modified technique for the excision of dumbbell-shaped keloids on the earlobe using tools common to every dermatologist's office. METHODS: This was an observational report on the outcomes of dumbbell keloid excision using a #15 blade and punch biopsy. Eligible individuals were those with dumbbell-shaped keloids located on the earlobe. All procedures were conducted at an urban dermatology clinic. RESULTS: When combining the technique with continual compression earrings and intralesional corticosteroids, excellent cosmetic outcomes and minimal recurrence were achieved. CONCLUSION: The pairing of a #15 blade and punch biopsy has been demonstrated to produce a more user-friendly method for dumbbell keloid excision by dermatologists and clinicians without advanced surgical training.
