Role of liquid nitrogen alone compared with combination of liquid nitrogen and intralesional triamcinolone acetonide in treatment of small keloids.

Keloids are well-defined fibrous tissue overgrowths extending beyond the original defects. The purpose of our study was to compare the efficacy of liquid nitrogen cryosurgery alone with liquid nitrogen cryosurgery and intralesional triamcinolone acetonide combination. Study on 60 clinically diagnosed lesions of keloids from 21 patients was conducted to compare the efficacy of liquid nitrogen cryosurgery alone. The statistical analysis shows synergistic action of cryosurgery and corticosteroids may offer promise in the treatment.
