Études tomodensitométriques néonatales de l'os maxillaire dans les fentes labiopalatines unilatérales

The aim was to examine the bony maxillary structures by computed tomographic measurements in newborns with unilateral cleft lip and palate before cheiloplasty. Analysis of maxillary bone was performed and size parameters were measured by computed-tomographic analysis in 12 infants with unilateral cleft lip and palate. We compared the bony maxillary length and the bony maxillary width between the cleft side and the healthy side. For eight patients, the bony maxillary length was different between the cleft side and the healthy side. For three patients, the bony maxillary width was different between the incisor alveolar structure in the cleft side and the healthy side. For six patients, the bony maxillary width was different between the canine alveolar structure in the cleft side and the healthy side. We noted an asymmetry without hypoplasy in bony maxillary structure in newborns before cheiloplasty. The data can serve as the starting point for a control and later evaluation on the efficiency of different therapeutic approaches of alveolar and maxillary development in children with cleft lip and palate.
