Background: Treatment options for cutaneous striae are very limited.
Objective: To determine if subcision is an effective treatment for cutaneous striae and compare a combination with
0.1% tretinoin cream against a single treatment.
Methods: 14 patients were evaluated, each with 3 white striae. One stria received treatment with subcision, one with
tretinoin cream in a 0.1% concentration, and one with subcision plus tretinoin. The length of follow-up was 3 months.
Two blind investigators evaluated improvement by comparison of the initial and final digital photographs.
Results: Only 7 patients completed 3 months follow-up. A decrease of width and clinical improvement was observed
with the 3 treatments. However, some striae showed no change at all and there was no statistically significant difference
between treatments. Three patients presented necrosis in striae treated with subcision.
Conclusions: There are no studies in the medical literature about subcision for the treatment of cutaneous striae. This
is a preliminary study and considering the undesirable effects of necrosis in a high percentage of striae treated with subcision,
the subjective way of evaluation, and the small study group, we can not recommend subcision as a treatment for
cutaneous striae. Large studies are necessary to corroborate or to discard our findings.
