Features of Maxillary Arch and Nasal Cavity in Infancy and Their Influence on Deciduous Occlusion in Unilateral Cleft Lip and Palate

The palatal forms in 20 infants with a complete unilateral cleft lip, and palate (12 with a Hotz plate and 8 without, selected at random) were studied from birth until 18 months of age. Using techniques developed previously, the degree of curvature In the palate and the magnitude of migration of the maxillary segments were measured three-dimensionally. Furthermore, using a newly developed method to approximate a set of the points on the alveolar ridge to a circle in a plane, the form of the alveolar arch was evaluated. Results from the group with a Hotz plate revealed that the plate possesses four effects not seen in the group without a Hotz plate. The size of the palate was larger, and the sagittal gap between the two segments of the maxilla was smaller. These results suggest that the appliance could stimulate the growth of the segments and could prevent collapse of the maxillary arch from the force of lip closure. Third, the steepness of the segments toward the nasal cavity was smaller, possibly occurring because the appliance prevents tongue intrusion into the cleft. Fourth, the magnitude of migration of the lesser segment toward the cleft edge of the major segment was larger. This result suggests that the appliance could guide the growth of the maxillary segments to narrow the cleft width until 18 months of age.

Maxillary Arch

The focus of this study was an analysis of maxillary arch growth changes prior to the time of cheiloplasty up to 4 years of age. Serial dental casts were obtained and measured in 95 children with cleft lip and palate, or both: 7 unilateral cleft lip and alveolus (CLA), 52 unilateral cleft lip and palate (UCLP), 24 bilateral cleft lip and palate (BCLP), and 12 isolated cleft palate (CP). The children were treated at the Kyushu University Dental Hospital. The results are as follows: (1) Prior to cheiloplasty, the maxillary buccal segments in the subjects with cleft lip and palate showed lateral displacement. The premaxilla in BCLP subjects was protruded. (2) Cheiloplasty influenced maxillary anterior arch width, but not posterior width. The operation caused posterior displacement of the premaxilla in BCLP subjects. (3) Palatoplasty affected the growth of the maxillary arch in the transverse and anteroposterior dimensions. (4) A variety of growth patterns observed in the patients (e.g., increasing or decreasing of the maxillary arch dimensions) suggests that maxillary arch dimensions were affected not only by surgery, but also by other individual factors such as genetic facial pattern and severity of the cleft.

Maxillary Arch

Serial frontal and lateral cephalometric radiographs with implants and study models of 31 infants' who received orthopaedic treatment for unilateral cleft lip and palate, were analysed with an electronic XY reader. Partial data for 50 normal infants and 10 isolated palatal cleft patients were included to allow certain comparisons. The records at birth indicate that the size of the alveolar cleft in unilateral cleft cases is governed mainly by the degree of transverse segmental separation which is present and only to a lesser extent by deficiency of alveolar tissue, except in a minority of cases. It is clear that in the early months of life, the divided maxillary arch can be made to assume near normal dimensions by inward rotation of the anterior ends of the segments, at the alveolar and basal level, around axes in the tuberosity regions. Appositional growth of the cleft margins makes little contribution to the reduction in cleft size. The significance of the findings is discussed.
