Introduction; Cleft palate represents the third most frequently congenital deformity and oronasal fistula is considered as one of the most common postoperative complication. Aim of study: We evaluated the effect of adjunctive use of low level laser LLL after surgical correction of cleft palate in improving healing and decreasing incidence of oronasal fistula occurrence. Methods; This study was randomized clinical trial enrolled 34 pediatrics with isolated cleft palate treated by von Langenbeck technique and they randomly distributed into two group ; case group treated postoperative with Adjunctive LLL and control group without Adjunctive use of LLL postoperative Results; The mean age for case group was 9.6±1.5 months and 8.7±2.2 months in control group, with no statistically significant difference, better results were found in laser group as ; the pain decreased in laser group at 58.8%in 1st day and 41.2% in 3rd day on other hand in control group 41.2%, 47.1% and 11.8% in 1st ,3rd and 5th day respectively. Edema disappeared at day 3 and 5 of follow up between cases (76.5% and 23.5% respectively) and controls (47.1%, 52.9% respectively) with statistically insignificant difference. Hyperemia disappeared with statistically higher participants at 3rd day follow up in cases (64.7%), in comparison to controls (23.5%).The fistula incidence in current study was(5.9%) 2 cases one in each group
