Comparative Efficacy of Fractional CO Laser Combined with Topical Steroid Cream versus Solution for Post-Thyroidectomy Scar Treatment: A Prospective Study.

BACKGROUNDS

Post-thyroidectomy scarring is a common illness impacting patient quality of life. Fractional carbon dioxide (CO) lasers and topical steroids delivered via laser-assisted drug delivery (LADD) have shown potential for scar treatment. However, ideal steroid formulations (cream vs. solution) when combined with laser therapy remain unclear.

METHODS

This study included 12 patients receiving fractional CO laser on post-thyroidectomy scars. After laser treatment, one scar half received topically applied steroid cream, while the other half received steroid solution. The Patient and Observer Scar Assessment Scale (POSAS) was used to measure the scar conditions at the time prior to the first treatment and one year later by the patients themselves and by the surgeon who did the laser treatment. Scar appearance was photographically assessed at baseline and 6 months post-treatment by four blinded evaluators using scales.

RESULTS

This study discovered a modest improvement in the appearance of post-thyroidectomy scars when combining fractional CO laser treatment with either topical steroid cream or solution. Patients and treating physicians examined the POSAS scores one year after treatment found significant improvements in all aspects of the scar conditions, with high efficacy and satisfaction levels reported by patients.

CONCLUSIONS

Fractional CO laser combined with topical steroid delivery, either cream or solution form, significantly enhanced post-thyroidectomy scar appearance with modest effect and high patient satisfaction. This approach may represent a promising scar management strategy along with current scar treatment for the post-thyroidectomy scar.
