Since 1981 we have been conducting investigations in Aichi Prefecture where our institution is located in close cooperation with Medical Association of Obstetrics-Gynecologists and member physicians of the Midwives Association. In addition, we surveyed 111 institutions in Gifu Prefecture for the patient who was delivered from January 1, 1986 to December 31, 1987 to learn the incidence and type classification of cleft lip and/or palate in the general population Gifu. Consequently, we acquired the date of 20667 newborns. It was found as a result that 35 babies had these abnormalities and that ratio of the birth of such newborns was one for 590.5 deliveries. Among 35 cleft infants 12 (34.3%) with cleft lip and palate, 5 (14.3%) cleft palate. Looking at the estimates from the results of our investigation, the annual number of newborns with these disease in the Gifu Prefecture was 41.6 to 41.9 in 1986, 33.5 to 33.6 in 1987 with 95 percent confidence limits.
自1981年以来，我们一直在与爱知县的妇产科医师协会及助产士协会的成员医师密切合作，在我们所在的爱知县开展调查。此外，我们对岐阜县的111家机构在1986年1月1日至1987年12月31日期间分娩的患者进行了调查，以了解岐阜县普通人群中唇裂和/或腭裂的发病率及类型分类。因此，我们获得了20667名新生儿的数据。结果发现，有35名婴儿患有这些异常，此类新生儿的出生比例为每590.5次分娩中有1例。在35例唇腭裂婴儿中，12例（34.3%）为唇腭裂，5例（14.3%）为腭裂。根据我们的调查结果估算，岐阜县1986年患有这些疾病的新生儿年数量在41.6至41.9例之间，1987年在33.5至33.6例之间，置信区间为95%。
