ABSTRACT
Introducción: Las estrías de distensión son frecuentes y representan un problema estético importante. Se han intentado múltiples terapias, no habiendo ninguna realmente efectiva. Objetivo: Evaluar respuesta al tratamiento con láser fraccional en estrías de distensión. Método: Estudio retrospectivo en trece pacientes con estrías. Fueron tratados con cuatro sesiones de láser fraccional Er: Glass Mosaic Lutronic ®. Se consignó edad, sexo, tipo de estría (roja o blanca), causa (posembarazo, adolescencia y otras) y fototipo. Fueron evaluados con control fotográfico y una escala de satisfacción subjetiva. Para el análisis estadístico se utilizó el test exacto de Fisher. Resultados: Se incluyeron trece pacientes. Nueve pacientes (69,2 por ciento ) consideraron una franca mejoría después del tratamiento, tres(23,1 por ciento) una mejoría parcial y un caso (7,7 por ciento), ausencia de cambios. No hubo diferencias significativas entre estrías blancas y rojas. Discusión: La terapia láser fraccional fue efectiva tanto para el tratamiento de estrías rojas como blancas.
Introduction: Stretch marks are common and represent a major cosmetic problem. Many therapies have been tried not being any truly effective. Objective: To evaluate response to treatment with fractional laser in distension stretch marks. Methods: A retrospective study in patients with stretch marks, who were treated with 4 sessions of fractional laser Er: Glass Mosaic Lutronic ®. We recorded age, sex, type of stretch mark (red or white), cause (post pregnancy, adolescence, etc.) and phototype. Patients were evaluated with photographic control and a subjective satisfaction scale. For statistical analysis we used the Fisher test. Results: We included 13 patients. 9 patients (69.2 percent had a marked improvement after treatment, three (23.1 percent) partial improvement and one case (7.7 percent), no change. There were no significant differences between white and red striae. Discussion: The fractional laser therapy was effective for the treatment of both red and white stretch marks.

BACKGROUND: Striae distensae are atrophic dermal scars with overlying epidermal atrophy causing significant cosmetic concern. Although a variety of laser and light sources have been used for the treatment of striae distensae, to date no definite 'gold standard' treatment modality has been determined. OBJECTIVE: To assess and compare the efficacy and safety of nonablative fractional photothermolysis and ablative CO2 fractional laser resurfacing in the treatment of striae distensae. METHODS: Twenty-four ethnic South Korean patients with varying degrees of atrophic striae alba in the abdomen were enrolled in a randomized blind split study. The patients were treated with 1,550 nm fractional Er:Glass laser and ablative fractional CO2 laser resurfacing. Each half of the abdominal lesion was randomly selected and treated three times at intervals of 4-weeks using the same parameters. Digital photography was conducted and skin elasticity and the width of the widest striae in each subject were measured at the baseline and 4 weeks after the final treatment. Clinical improvement was assessed by comparing pre- and post-treatment clinical photographs by two blinded physicians and participant satisfaction rates were evaluated. Skin biopsies were taken from three participants. All adverse effects were reported during the study. RESULTS: Although they do not statistically differ, both treatments with nonablative fractional laser and ablative CO2 fractional laser showed a significant clinical and histopathologic improvement of striae distensae over pretreatment sites. CONCLUSION: These results support the use of nonablative fractional laser and ablative CO2 fractional laser as effective and safe treatment modalities for striae distensae of Asian skin. However, neither treatment showed any greater clinical improvement than the other treatment.
