Do the dimensions of the hard palate have a relationship with the volumes of the upper airways and maxillary sinuses? A CBCT study

Abstract Background As the hard palate is a central structure of skull, and its close relationship with nasal cavity, oral maxillary sinuses, it would be interest to study if there between this bone other structures stomatognathic system. Thus, aimed assess dimensions associate them sex, skeletal breathing patterns. Also, investigate these volumes upper airways sinuses. Methods Two hundred ninety-eight CBCT scans patients were classified according Then, linear width height at regions first premolars molars, sinuses measured using CS 3D Imaging ITK-SNAP software, respectively. Data submitted multi-way analysis variance regression, significance level 5% (α = 0.05). Results Sex facial type influenced ( p < Males had greater than females 0.0001). It was observed for brachycephalics region 0.0032), dolichocephalics 0.0154) molars 0.0038) regions. Skeletal malocclusion pattern did not influence measurements > There significant premolar’s total volume 0.018, 0.038), both molar’s Conclusions The are by sex type, but or pattern. an association
