Abstract

|
Background: Various treatment modalities for hypertrophic scars and keloids have been used. However, there is no consensus as to what the optimum approach should be. Most common treatments are corticosteroid intralesional injection (ILI) and cryotherapy as well as combination of these two modalities. To this date, however, there are no prospectively comparative, scar-split studies between steroid ILI monotherapy and combination of steroid ILI and cryotherapy.
Objective: The purpose of this article is to investigate and compare the efficacy of steroid ILI monotherapy and the combination of steroid ILI and cryotherapy.
Methods: Eighteen women who had thyroid operation scars were recruited. Patients received steroid ILI with cryotherapy on the right half, and steroid ILI monotherapy on the left half of the scar. Patients were treated for four sessions with three weeks of intervals. Subjects were evaluated on their scar status with the modified Vancouver scar scale (MVSS) and scar redness by using colorimeter at baseline and every visit day.
Results: After four treatment sessions, MVSS was significantly improved on both sides of scar. Significant improvement was observed after one treatment session on the right half, and after two treatment sessions on the left half. There was no significant difference between left and right side after four sessions of treatment. The scar redness of both sides of scar showed no significant differences between the baseline and at the end of the study.
Conclusion: Both corticosteroid ILI with cryotherapy and corticosteroid ILI monotherapy are effective treatment modalities for hypertrophic scars. However, the results of the present study suggest that a combination therapy might lead to more rapid improvements.
