Effectiveness of Long Pulsed Nd:YAG Laser 1064 in Treatment of Scars

Abstract

This is a prospective clinical descriptive study, aimed to detect the efficacy of and safety of long pulsed Nd: YAG laser (1064 nm) in treatment of scars in some Sudanese patients.The study was performed in Khartoum Dermatology & venerology Teaching Hospital and Institute of Laser in Sudan University of Science and Technolgy. The study was conducted from October 2017-April 2018. Objectives of this study are to determine efficiency of long pulsed Nd: YAG laser in the treatment of scars, to assess clinical effect of NDYAG laser 1046 in scars treatment and to find possible side effects. Ten patients (all females) presented with skin scars, they were selected from outpatient clinic in Khartoum Dermatology & venerology Teaching Hospital and other dermatology clinics and were considered as study population. Type of scars (atrophic or hypertrophic), area of scar and skin phototype were took into consideration in this study. The laser system used in this study was long pulsed Nd-Yag laser 1064 nm. All patients received the same laser parameters of long pulsed Nd-Yag laser.The probe was applied over the scar with a wave length of 1064 nm, energy density of 15 J /cm2, pulse duration of 5 sec, 5‐mm spot size, 5‐Hz pulse rate with covering of all the surface area of the lesion. The frequency of treatment was three sessions of laser with three weeks apart iii There is improvement in appearance of scars after the third session in almost all cases, and the study showed that the use of long pulsed Nd-Yag laser in treatment of skin scars is promising. Further studies with more patients and extended period of time are recomended.
