Cleft lip is a common craniofacial anomaly and aesthetic obstacle. Different procedures, techniques, and steps are required for repair. These procedures may result in secondary abnormalities or volume deficiencies that can be managed by different methods such as autologous fat grafting. We aim through this study to identify the technique of autologous fat graft in cleft lip deformity and the patient characteristics for selecting this particular technique. This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The study systematically reviewed MEDLINE, Cochrane, and EMBASE databases without time-limitation. A total of 14 articles published in the period between 2004 and 2022 were included, then patients in each study who did not meet the inclusion criteria were excluded. A total of 519 patients who underwent autologous adipose tissue augmentation of cleft lip deformity were included and analyed. Autologous fat graft is found to be safe, effective in improving lip appearance as well as contour, and associated with high satisfaction rate among cleft lip patients. A selected patients with vermilion deficiency, whistle deformity, or overall lip volume deficiency is found to have a higher satisfaction rate. The most frequently reported complications were excess fullness, nodule formation, graft resorption, and nostril deformity.
