Background Cleft lip and cleft palate are the most common congenital anomalies in the head and neck region, which are affected by environmental and genetic factors. These anomalies can cause serious problems such as physical deformity, nutritional problems, respiratory problems, and problems in social interactions for affected people. Objective The current study aims to investigate the prevalence of lip and palate clefts and the related factors in infants born from 2014 to 2019 in Karaj, Iran. Methods This descriptive-analytical study was conducted on the data of 91,563 babes born from 2014 to 2019 in Kamali, Imam Ali, Maryam, and Ghaem hospitals in Karaj, Iran. The data were collected and analyzed in SPSS software, version 24. Results Of 91,563 cases, 46 were identified with various types of clefts. The overall prevalence was 0.5 per 1000 live births; 26.08 had cleft lip, 52.17% had cleft palate, and 21.73% had cleft lip and palate (P=0.024). Also, 56.52% of babies were male (P=0.37), 76.08% had mothers aged 20-30 years with a mean age of 24.4 years, 58.69% had first-time pregnancy mothers, 13.03% had parents with cousin marriage (P<0.001), and 37% had mothers with blood type A (P=0.11).
