采用点阵式二氧化碳激光对甲状腺切除术后瘢痕进行早期治疗

Background:

Ablative carbon dioxide fractional laser systems (CO2 FS) have been effectively used to improve the appearance of scarring after surgical procedures, but an optimal treatment time has not been established.

Objective:

To evaluate the efficacy and safety of CO2 FS in early postoperative thyroidectomy scars.

Methods:

Twenty-three Korean women with thyroidectomy scars were enrolled in this study. All patients underwent a single session of two passes of a CO2 FS with a pulse energy setting of 50mJ and a density of 100spots/cm2 2 to 3weeks after surgery.

Results:

Mean Vancouver Scar Scale (VSS) scores were statistically significantly lower after laser treatment. Three months after CO2 FS treatment of thyroidectomy scarring, 12 of 23 participants showed clinical improvement of more than 51% from 2 to 3weeks after surgery. The mean grade of clinical improvement based on independent clinical assessment was 2.6±0.9.

Conclusion:

Early postoperative CO2 FS treatment of thyroidectomy scars is effective and safe.
