A New Uniform Protocol of Combined Corticosteroid Injections and Ointment Application Reduces Recurrence Rates After Surgical Keloid/Hypertrophic Scar Excision

Background Published reports indicate that corticosteroid injections can prevent recurrence after keloid excision, but the side effects of repetitive intralesional steroid injections may preclude treatment maintenance. Additionally, few of these studies employed a standardized treatment protocol. Objectives To analyze the results of a new uniform treatment protocol combining corticosteroid injections and ointment application designed to reduce recurrence rates after excisional surgery in individuals with keloids or hypertrophic scars. Methods As a standard procedure, the first corticosteroid injection took place after removal of the sutures and then once every 2 weeks after that until it had been done five times. In addition, all postsurgical wounds received self-administered steroid ointment application twice daily for 6 months after suture removal. Results Postoperative follow-up in this series ranged from 24 to 57 months (median 32 months, mean 32.5 months). Recurrence occurred in three of the 21 keloid cases (14.3%) and one of the six hypertrophic scar cases (16.7%). Conclusion We evaluated a new standardized adjuvant corticosteroid therapy to prevent recurrence after surgical keloid or hypertrophic scar excision. Using this method, we achieved low recurrence rates.
