Abstract

Background:

Silicone sheet is commonly used for scar management but hard to apply to irregular surfaces or mobile areas, and difficult to conceal. On the contrary, silicone gel is easy to apply and nearly unnoticeable. Therefore, we conducted this study to compare their effectiveness.

Methods:

Patients undergoing horizontal cesarean section were included. Surgical wounds were divided into 2 halves. Patients randomly applied silicone sheets and silicone gel on either side of their wounds for 3 months. The wounds were assessed at 1, 3, 6, and 12 months after surgery. We used the Vancouver Scar Scale (VSS) for an objective evaluation and the visual analog scale (VAS) for a subjective evaluation.

Results:

There was no statistical significance between the silicone sheet and silicone gel groups with respect to VSS score. The silicone sheet group showed a statistically significant higher VAS score for itch at 1 month follow-up (1.18 ± 2.04 vs 0.35 ± 0.85, P = .01). However, the difference was less than 1 on a scale of 10, so it might not be clinically meaningful.

Conclusion:

Silicone sheet group showed statistically significant worse VAS score in terms of itch. However, the difference was too small to be clinically meaningful.
