Avaliação comparativa das características oclusais e craniofaciais de crianças com síndrome da apneia obstrutiva do sono(SAOS) apresentando ou não atresia transversal da maxila

Abstract

Objective: To comparatively evaluate the occlusal characteristics of children with obstructive sleep apnea syndrome with or without transverse maxillary atresia. Material and method: this analysis was made in plaster models where some measurements were made to make the comparison possible. The set of information was obtained by measuring the plaster models of the patients with the aid of a caliper, and with the data obtained, a statistical survey was made to correlate these facts. Two groups of patients were evaluated, one with atresia and one without maxillary atresia, both underwent the tonsils and adenoids removal procedure, so that they could be part of this study. Results: In the group of patients without maxillary atresia, the correlations: superior intercanine distance versus superior perimeter; upper intermolar distance versus upper arch perimeter showed statistical difference (P <0.05). While the overjet versus upper length correlation showed no statistical difference. In the lower arch of patients without atresia, the situation was similar. In the group of patients with maxillary atresia, the correlations: upper intercanine distance versus upper perimeter showed statistical difference. While the correlations between upper intermolar distance versus upper perimeter, and upper arc length versus overjet correlations did not indicate statistical difference. In the lower arch, the intercanine distance versus perimeter, intermolar distance versus perimeter, and length versus overjet showed no statistically significant difference. Conclusion: Statistical data on the relationship between these groups showed that there is a statistically significant relationship between some data showing that patients with atresia have greater jaw dysmorphism than those without atresia, which shows that only adenotonsillectomy surgery is not sufficient treatment for these patients with atresia, so it is necessary to use an intraoral device to correct this disruptive jaw.
