Objectives: 1. Understand the characteristics of ear helix keloid scars.
2. Develop an appropriate treatment plan for ear helix keloid scars.
3. Understand laser treatment for ear helix keloid scars.
Introduction: Keloid scars can occur in the ear, shoulder and deltoid area, chest, abdomen, perineum, face and neck, but most commonly in the earlobe. Most earlobe keloid scars occur on the lobule area. In recent years, however, piercing and earrings have become more common in the upper part of the ear as well as in the lower part of the ear, resulting in increased keloid scars in the helix area of the ear. The helix area in earlobe is often connected to or composed of the cartilage, unlike the lobule area. Therefore, surgical methods often cause deformation of the ear.
Materials / method: Carbon dioxide laser has less bleeding during operation, less risk of infection, and is very effective at removing soft tissue. Especially, ultrapulsed carbon dioxide laser is known to have a short pulse duration and less damage to surrounding tissue during laser treatment. We treated keloid scars in the ear helix by vaporization with carbon dioxide laser after local anesthesia. After the laser treatment, corticosteroid injection was performed every 1-4 weeks.
Results: We followed up for more than 6 months, but the recurrence of keloid scars or side effects of treatment were observed rarely.
Conclusion: I think carbon dioxide laser in conjunction with corticosteroids as an effective and safe method for the treatment of ear helix keloid scars.
