Background
At present, there are many kinds of hypertrophic scar treatment methods, among which pressure therapy and silicone therapy are very common and standard therapies, but whether they are used alone or in combination is still controversial. Therefore, the purpose of this systematic review was to compare the efficacy and safety of the combination of pressure therapy and silicone therapy (PTS) with pressure therapy alone (PT) in the treatment of hypertrophic scars to provide clinicians with information so that they can make better decisions.
Methods
Relevant randomized controlled trials (RCTs) were collected by searching PubMed, Ovid MEDLINE, Embase, ScienceDirect, Web of Science, The Cochrane Library, Scopus, and Google Scholar databases to assess scar scores (The Vancouver Scar Scale, VSS; Visual Analog Scale, VAS) and adverse effects.
Results
We screened 1270 articles and included 6 RCTs including 228 patients. We found that height (MD = 0.15, 95%CI 0.10–0.21, p < 0.01) and pliability (MD = 0.35, 95%CI 0.25–0.46, p <0.01) had a significant difference, these two measures showed that the PTS group was superior to the PT group. Results in other aspects, such as VSS, vascularity, pigmentation, VAS, and adverse effects were similar between the two groups.
Conclusions
There was no significant difference between PTS and PT in the overall treatment efficacy of hypertrophic scars with similar VSS and adverse effects, but PTS might have potential benefits for height and pliability. Additional studies with larger sample size and sound methodological quality are needed to confirm our conclusions.
