Application of mitomycin-C for head and neck keloids.
Keloids of the head and neck are a relatively common entity in darker-skinned races, occurring in 5%-15% of skin wounds. Keloids are fibrotic lesions that are a result of an abnormal wound-healing process that lacks control of the mechanisms that regulate tissue repair and regeneration. The proliferation of normal tissue-healing processes results in scarring that enlarges well beyond the original wound margins. Many treatment modalities for keloids have been tried with variable amounts of success. Surgical excision, compressive therapy, silicon dressings, corticosteroid injections, radiation, cryotherapy, interferon therapy, and laser therapy have all been used alone or in combination. Despite this wide range of available treatments, recurrence rates typically remain in the 50%-70% range. In this study, we present our results in a series of 10 patients who were treated with surgical excision of head and neck keloids and the application of topical mitomycin-C. Mitomycin-C is a chemotherapeutic agent that inhibits DNA synthesis and fibroblast proliferation. It has been used in ophthalmologic procedures and airway surgery to decrease scar formation. In these 10 patients, we combined surgical excision of keloids with the application of topical mitomycin-C. The patients were then followed postoperatively for recurrence (range, 7-14 months). We have found topical application of mitomycin-C to be an effective therapy for prevention of keloid recurrence in the head and neck, with a success rate of 90% as reported in this series.
