[The risk factors in assessing the overall and local status of children with congenital cleft upper lip and palate before cheiloplasty].

Assessment of the status of more than 2000 children with cleft lip and palate before cheiloplasty brought the authors to a conclusion that obturators should be used as early as possible in perforating defects in order to allow breast feeding and prevent the progress of the deformation; iron-deficiency anemias, thymomegaly, and virus carrier state are to be timely detected and corrected as well as the concomitant developmental defects in order to prevent the postoperative complications.
