Treatment options for cutaneous striae are very limited. To determine if subcision is an effective treatment for cutaneous striae and compare a combination with 0.1% tretinoin cream against a single treatment. 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. 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. 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.
