What is the role of intralesional corticosteroid injections for keloids before considering surgery?

BACKGROUND Keloid scars are common cutaneous lesions encountered by plastic surgeons. They are distinguished from normal scars and hypertrophic scars by their ability to spread outside the boundaries of the original scar. Corticosteroids are a mainstay of treatment, and their effectiveness is thought to be due to the inhibition of fibroblast growth and the promotion of collagen degradation. The treatment of keloids is challenging and recurrence rates are high. Intralesional steroid injection, specifically triamcinolone combined with surgical resection, has become common practice; however, there are no researchsupported guidelines or proven algorithms for the number of injections necessary before proceeding with surgery
