Resumo

Introducción: Los resultados de la remoción de tatuajes con láser de sesión a sesión según los parámetros utilizados son limitados en la literatura. Objetivo: Evaluar los cambios en el aclaramiento de tatuajes y factores asociados posterior a una sesión con láser y los efectos adversos. Materiales y Métodos: Estudio longitudinal retrospectivo de antes y después de 1 sesión de con láser para remoción de tatuajes, donde se determinaron parámetros del tratamiento, aclaramiento y efectos adversos. Resultados: Se evaluaron 35 pacientes para un total de 98 sesiones, fototipo de piel II y IV. Equipos utilizados laser Q-Switch Nd Yag 1064 (83.3%), láser Q-Switch Nd YAG 532(11.3%) y laser Q-Switch Rubí (4.1%). El aclaramiento posterior a la sesión de láser fue evaluado por dos evaluadores independientes, mostrando concordancia significativa (Kappa de 0.615, p<0.001), con aclaración en un 96% de los tatuajes después de la sesión de láser. (p< 0.001). Se encontraron cambios significativos entre la densidad de energía aplicada y las categorías de aclaramiento de la escala de 0 a 3, siendo a mayor densidad mayor el nivel de aclaramiento (p= 0.05). No se encontró asociación significativa entre el número de pases y el aclaramiento del tatuaje. Los efectos adversos fueron del 5.4%. Cicatriz 2%, hiperpigmentación 2% y hipopigmentación 1%. Conclusión: Posterior a una sesión de remoción de tatuajes con láser Q-Switch hay un aclaramiento significativo en un 96% asociado con la densidad de energía, a mayor densidad de energía mayor el nivel de aclaramiento y no al número de pases realizados.

Introduction: Treatment outcomes of laser tattoo removal from session to session depending on the laser parameters used are limited in the literature. Objective: To evaluate changes in the clearance of tattoos associated factors and adverse effects after laser tattoo removal session. Materials and Methods: A retrospective longitudinal before and after study of 98 sessions in 35 patients in whom treatment parameters, clearance and adverse effects were determined after the session. Results: 35 patients were evaluated for a total of 98 sessions, skin phototype III- IV. Equipment used laser Q -Switch Nd Yag 1064 (83.3 %), laser Q -Switch Nd YAG 532 (11.3 %) and Q-switched ruby laser (4.1 %). Clearance after one session of tattoo removal was evaluated by two independent evaluators, showing significant agreement (kappa 0.615, p < 0.001), with significant a clearance of tattoos by 96 % (p < 0.001). Significant changes were found between the energy density applied and the clearance category scale from 0 to 3, at higher applied energy density a higher clearance level (p= 0.05), there was no significant association between the number of passes and clearance of the tattoo. Adverse effects were 5.4%, scar 2% , hyperpigmentation 2% and hypopigmentation 1% Conclusion: After a session of laser tattoo removal there was a high clearance of 96% associated with energy density applied , with a higher energy density a higher clearance level, but not to the number of passes.
