[Etiology of Cheilognathopalatoschisis (author's transl)].

Cheilognathopalatoschisis of the "common" type is a disturbance which goes beyond the actual region of the cleft and almost regularly involves the dental system as a whole, namely in the form of hypodontia. Whether the cleft and hypodontia anlage also affect the growth of both jaws in the sense of progenia is still not known. Equally, the question whether the pathogenetically different types of cheilognathopalatoschisis and isolated cleft palate can be separated etiologically from each other is not yet definitely clarified.
