The prevalence of cleft lip and palate in the Japanese: their birth prevalence in 40,304 infants born during 1982.
To determine the prevalence of cleft lip and palate (CL/P) among the Japanese, 40,304 infants born between Jan. 1, 1982, and Dec. 31, 1982, were investigated. Eighty-three infants (0.206%) were found with these abnormalities in approximately 2.06/1000 live births. Among fifty-two infants in whom it was possible to classify the types of cleft, seventeen (32.7%) had cleft lip only (CL), twenty-four (46.1%) had cleft lip and palate (CLP), and eleven (21.2%) had isolated cleft palate (CP).
