It has been suggested that among American Indians, as in some genetically-related Asiatic ethnic groups, incidence of cleft lip and/or cleft palate is higher than among people of Caucasian extraction. Such hypothesis, plus growing demand for services observed at a center for the surgery of cleft lip and cleft palate in Campeche state, led the authors to undertake research among the Maya residents of that region. However, neither careful review of case histories nor field research performed in several Indian communities could confirm the hypothesis of a higher incidence among this ethnic community.
有人提出，与一些有基因关联的亚洲族群一样，美国印第安人中唇腭裂的发病率高于高加索裔人群。这一假设，再加上坎佩切州一家唇腭裂手术中心观察到的对服务需求的不断增长，促使作者在该地区的玛雅居民中开展研究。然而，对病历的仔细审查以及在几个印第安社区进行的实地研究都无法证实这一族群中发病率较高的假设。
