Utilization of Carbon Dioxide Laser 10600nm In the Treatment of Seborrheic Keratosis in Some Sudanese Patients

Abstract

experience in Sudan. The response of treatment was evaluated clinically on base of lesions clearance after 6 weeks of the laser session. The results were as follows: excellent in 70% of the patients (seven patients), and Very good in 30% of the patients (three patients). All patients (100%) acquired pain and oedema immediately after the laser session, where these are common side effects of any laser. (60%) of the patients received hyperpigmentation 2 weeks after the session, due to post inflammatory hyperpigmentation which resolved 6 weeks later. This study aimed to use the C02 laser to treat the seborrheic keratosis as a sign of chronological aging that associated with the passage of time that give signature in the skin clinically as skin laxity, wrinkling, dispigmentation, telangiectasis pigmented seborrheic keratosis on sun-exposed sites due to the repeated exposure to ultra violet radiation (UVR). The main objective for this study was the testing of the effects of C02 laser 10600 nm in the treatment of seborrheic keratosis in Sudanese patients. This study was conducted in laser institute, Sudan University of Science and technology, during the period from May to Sep 2014. Ten patients clinically diagnosed as cases of seborrheic keratosis , were randomly selected for this study from different dermatological clinics in Khartoum State, considered as study population. Using C02 laser 10600 nm , power 5 watt , pulse duration 0.1 second, single pulse mode in one session as first choice for treatment of seborrheic keratosis lesions. All the patients signed a written informed consent ethical clearance The response of treatment was evaluated clinically on base of lesions clearance after 6 weeks of the laser session. The results were as follows: excellent in 70% of the patients (seven patients), and Very good in 30% of the patients (three patients). All patients (100%) acquired pain and oedema immediately after the laser session, where these are common side effects of any laser. (60%) of the patients received hyperpigmentation 2 weeks after the session, due to post inflammatory hyperpigmentation which resolved 6 weeks later.] From the obtained results one can conclude that C02 laser was very efficient in the treatment of seborrheic keratosis lesions. More work is needed in this field and in the field of laser application in dermatology to establish this experience in Sudan
