Silicone gel versus combination of silicone gel and a 577-nm diode laser in the treatment of post-surgery hypertrophic scar (comparative study).

BACKGROUND

Hypertrophic scars, resulting from alterations in the normal processes of cutaneous wound healing, are characterized by proliferation of dermal tissue with excessive deposition of fibroblast-derived extracellular matrix proteins, especially collagen, over long periods, and by persistent inflammation and fibrosis. The present study aim to compare the efficacy of silicone gel versus combination of a 577-nm pro- yellow laser and silicone gel in the treatment of post-surgery hypertrophic scar.

METHODS

This study is a randomized comparative study In the period from 14 January 2021 up to the end of January 2023. 30 patients with post-surgery hypertrophic scar divided into two groups: A: one half of scar was managed with 577 nm diode laser 3 sessions monthly combined with application of silicone gel at home. A + B: the entire scar was treated with silicone gel within six months who admitted to the Laser unit of the Dermatology and Andrology Department at Al-Azhar University Hospital, Assiut during the study period.

RESULTS

Significant improvement in pigmentation, pliability, height and total Vancouver score. By comparing between silicone gel and combination of silicone gel and a 577 nm diode laser, the combination shows significant improving than silicone gel alone. The scar in the lip and breast area showed a significant higher improvement rate with yellow laser plus silicone gel compared to the other site.

CONCLUSION

Combination of silicone gel and yellow laser has significant effect in making surgical scars less distinct.
