This investigation was carried out by the European Cleft Lip and Palate Research Group. The purpose of this part of the investigation was to compare and evaluate maxillary asymmetry in children born with complete unilateral cleft lip and palate treated at cleft palate centers with different surgical management. Posteroanterior radiographs from three of the six participating centers were included in the investigation. Statistically significant differences were found in the symmetry of the anterior part of the maxillary complex. Children with a primary bonegrafting procedure involved in their primary treatment procedure had a more symmetric dentoalveolar development. Children from centers with primary surgical procedures including a vomer plasty and no involvement of the alveolar process had a more asymmetric development with a tilted premaxilla and a deviating inclination of the central incisors.
