[The classification of congenital clefts and defects of the palate after uranoplasty. The clinico-embryo-pathogenetic principles].

: The authors suggest classifying palatal clefts as an individual nosological entity resultant from impaired differentiation, growth, and fusion of primary embryonal structures forming the palate as an anatomical structure. Definition of the palatal interface on the basis of the embryo-pathogenetic principle underlies the working classification of palatal defects developing after uranoplasty.
