Tranilast as an Additional Treatment with Conservative Therapy for Concave Deformity Following Traumatic Hematoma

Fibrotic scar tissue resulting from a cheek hematoma sometimes seriously contracts to form a concave deformity, despite conservative therapy. We used Tranilast as an additional treatment with conservative therapy for four patients who were resistant to massage and compression therapy. Four months after oral administration of Tranilast, all the deformities were resolved. Tranilast is used for the treatment of allergic diseases and keloids. It inhibits the release of transforming growth factor b-1, interleukin-1 b, and prostaglandin E2. It also suppresses collagen synthesis by fibroblasts.
