Treatments for ear lobe keloids include surgical excision, postoperative radiotherapy, steroid injection, and stabilization. However, to date, there is no universally accepted treatment strategy for earlobe mass therapy. A total of 140 lesions in 114 patients who were treated by surgery since 2006 were included and classified as primary keloids, recurring keloids and hypertrophic scars. Appropriate surgical approaches, postoperative radiotherapy, and postsurgical self-management were applied. Primary earlobe keloids were treated by wedge excision, but recurrent keloids needed to be reconstructed using Z-plasty or a V-Y flap. The postsurgical radiotherapy modalities were 10 Gy administered in three fractions over 2 days. Recurrence during the subsequent 18 month follow up period was recorded. Of the 140 lesions, 77.1% were primary keloids, 14.3% were recurrent keloids and 8.6% were hypertrophic scars. Their recurrence rates were 4.6%, 0% and 25%, respectively. Appropriate selection of surgical methods and postsurgical radiotherapy with 10 Gy radiotherapy administered in two fractions over 2 days can be used successfully to treat earlobe keloids.
