Epidemiology of cleft lip and palate in Singapore--a 10-year hospital-based study.
During the study period from January 1985 to December 1994, there were 1105 new cleft cases seen in the Department of Plastic Surgery, Singapore General Hospital. These included newborn as well as unoperated children and adult cases. During the same period, the total number of recorded births in Singapore was 474,542. ⋯ There was no significant difference in sex distribution; the male to female ratio was 1.1:1. However, females had a higher incidence of cleft palate than males. Associated congenital deformities occurred in 1.5% of the total cleft population.
