Abstract
The carbon dioxide laser (CO2 Laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964. CO2 laser is the highest power continuous wave lasers that are currently available which produces a beam of infrared light with the principal wavelength bands centering on 9.4 and 10.6 micrometers. Fractional CO2 laser resurfacing is a revolutionary delivery system that provides dramatic skin improvement without surgery. Cleft lip is a form of lip malformation that occurs very early in pregnancy, the incidence of cleft lip in the population is approximately 0.5-2 in 1000 live births. Male children are affected more often than female children. A visible scar will be left after cleft lip repair surgery and it may appear red, swollen and bruised after surgery, but this will fade considerably as it heals. One of the most important option in treating post cleft lip scar is fractional CO2 laser. This work aims to Evaluate the efficacy of fractional CO2 laser in the later appearance of cleft lip scar, presenting this technique for the post-operative care schemes of cleft patients in academic trials and accomplish parent’s satisfaction. This is a prospective comparative study on 120 patients divided to three groups, group I : 40 patients start laser treatment 3 weeks after surgical repair, group II : 40 patients start laser treatment 3 months after surgical repair, group III : 40 patients as a control from 2017 to 2019 which will be conducted on patients with post-surgical cleft lip repair scarring. All patients will have 5-7 sessions with 4 weeks interval , without restricted age. Photographic documentation and evaluation of the scar will occur every 4 weeks. Methodology Applications for evaluation of the scar: Vancouver scar scaleVisual Analogue ScaleScar Width Assessment It was noticed that total Vancouver Scar Scale score had insignificant differences between studied groups at baseline. During follow up period, it was noticed that total Vancouver Scar Scale score was significantly lower in group I (1.92 ± 0.88) in comparison to group II (3.70 ± 1.11) and group III (4.05 ± 1.29). Regarding scar width assessment it was noticed that scar width had insignificant differences between studied groups at baseline. During follow up period, it was noticed that scar width was significantly lower in group I (2.51 ± 0.64) in comparison to group II (3.17 ± 0.54) and group III (3.27 ± 0.48). In visual analogue scale It was noticed that physicians scale was significantly higher in group I (44.17 ± 3.45) in comparison to group II (36.53 ± 4.43) and group III (30.40 ± 5.22). Also, non-medical scale was significantly higher in group I (43.52 ± 4.20) in comparison to group II (37.52 ± 4.73) and group III (33.55 ± 4.85). At the end of our study we concluded that the use of fractional CO2 laser is very important in treatment of cleft lip scar and its early use is better than late use which in turn is much better than not using it.
