Awareness, knowledge and attitudes of Saudi pregnant women towards cleft lip and palate

The incidence of cleft lip (CL), cleft palate (CP), or a combination of both (CLP) has been studied worldwide. Globally, CLP occurs in approximately 1 in every 500-700 births per year [5]. Previous studies have reported that the incidence of CLP ranges from 1 to 2.2 per 1000 live births in European Caucasian population [6], whereas a study in Brazil reported a prevalence of 0.19 per 1000 live births [7]. Another study in Saudi Arabia reported the incidence of CLP as 0.3 per 1000 live births [3]. Prevalence of CLP varies with geographic origin and ethnic groups; however, these are not the only determining factors.
