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).
为确定唇腭裂(CL/P)在日本人中的患病率,对1982年1月1日至1982年12月31日期间出生的40304名婴儿进行了调查。在大约每1000例活产中有2.06例的情况下,发现83名婴儿(0.206%)患有这些异常。在52名能够对腭裂类型进行分类的婴儿中,17名(32.7%)仅患有唇裂(CL),24名(46.1%)患有唇腭裂(CLP),11名(21.2%)患有单纯腭裂(CP)。
