Background: Recent advances in keloid management favor the administration of combination therapy over monotherapy.
Objective: The authors evaluated the safety and efficacy of combination therapy to treat keloids using fractional lasers, cryotherapy, and intralesional corticosteroids.
Materials and methods: The authors performed a retrospective study involving 35 Korean patients. Each patient underwent treatment using the 1,550 nm nonablative fractional erbium-glass laser, followed by the 10,600 nm ablative fractional carbon dioxide laser. Laser treatment was immediately followed by the administration of superficial cryotherapy and intralesional triamcinolone injection. Therapeutic efficacy was assessed using the Vancouver Scar Scale (VSS) score and the 7-point patient self-assessment score.
Results: The mean total and subcategory VSS scores showed statistically significant improvements. The height and pliability scores showed the most significant and quickest responses to the combination therapy. The patients reported remarkable improvement in itching, pain, and limitations of motion after a single combination therapy session. Twenty patients were followed up for 1 year after the discontinuation of the combination treatment, and the recurrence was observed only in one patient. No significant adverse effects were observed throughout the follow-up period.
Conclusion: Combination keloid therapy using fractional lasers, superficial cryotherapy, and intralesional triamcinolone injection is safe and more effective than individual monotherapies.
