Fractional Carbon Dioxide (CO) Laser Alone Versus Fractional CO Laser Combined With Triamcinolone Acetonide or Trichloroacetic Acid in Keloid Treatment: A Comparative Clinical and Radiological Study.

Introduction: Keloids are benign fibro-proliferative scarring extending outside the initial wound. Different treatment modalities as intralesional corticosteroid injection, fractional CO laser, and others can be used either as mono or combined therapies.

Objectives: To assess the efficacy of fractional CO laser versus fractional CO laser accompanied with either triamcinolone acetonide or trichloroacetic acid 20% in keloid treatment clinically and radiologically.
