NAVAS-APARICIO, M. Carmen. Maxillary growth analysis after surgery in non-syndromic cleft palate. Cir. plást. iberolatinoam. [online]. 2016, vol.42, n.3, pp.247-254. ISSN 1989-2055.

Background and Objectives. The goal of closing the cleft palate is the restoration of the anatomic continuity between the oral and nasal cavities, in order to obtain a correct speech and a normal maxillofacial growth. The purpose of this study is to determine if there is a poor anteroposterior and transverse maxillary growth in children born in 2003 with non-syndromic isolated cleft palate, treated at the Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", San José, Costa Rica. Methods. The study was a cross-sectional, descriptive, interventional study, based on data from medical records and current records (cephalometric radiograph and maxillary study cast). Methods. The study group consisted of 5 patients. The statistical techniques used were frequency distributions, cross variables and mean comparison based on the analysis of variance. The minimum level of confidence for comparisons was 95%. Results. The average age of the primary palate surgery was 17 months old. The maxillary arch transverse asymmetry predominated in this study. There is a positive, high and statistically significant correlation between the difference in the anterior-posterior position of the maxilla with respect to the mandible. Conclusions. There is a maxillary arch cross asymmetry which could be influenced by secondary healing process palate to a surgically denuded bone. The anterior-posterior relationship is not affected. A study at different ages of children is recommended since the antero-posterior relationship can be expressed as a belatedly condition genetically determined.
