title: The prevalence of cleft lip and plate in Japanese.
abstract: To determine the prevalence of cleft lip and palate (CL/P) among the Japanese, 43,821 babies born between 1 January, 1985, and 31 December, 1985, were investigated. Sixty-four infants (0.146%) were found to demonstrate these abnormalities, a birth prevalence rate of 1.46/1000. Among 326 infants in whom it was possible to classify the types of cleft, born between 1 January, 1981, and 31 December, 1985, there were 111 (34.0%) with cleft lip (CL), 154 (47.3%) with cleft lip and palate (CLP) and 61 (18.7%) with cleft palate (CP).
