Answer

Corticosteroids, specifically intralesional corticosteroid injections, have been the mainstay of treatment. Corticosteroids reduce excessive scarring by reducing collagen synthesis, altering glucosaminoglycan synthesis, and reducing production of inflammatory mediators and fibroblast proliferation during wound healing. The most commonly used corticosteroid is triamcinolone acetonide (TAC) in concentrations of 10-40 mg/mL administered intralesionally with a 25- to 27-gauge needle at 4- to 6-week intervals.
