“…On the other hand, brachycephalic patients have a tendency of horizontal craniofacial growth, presenting a regular and larger hard palate. 3,21,23 This is in concordance with the results of this study, in which dolichocephalic and brachycephalic individuals presented greater values of height and width of the hard palate, respectively, at this region. In addition, the study of Fernandes et al (2017) 26 observed a trend towards vertical growth when the oropharynx permeability is reduced.…”

“…In view of this result, it is possible to observe the in uence of the vertical growth trend in the shape of the hard palate, since the greater vertical tendency of growth (dolichocephalic) presented greater height of the hard palate, while the greater horizontal tendency (brachycephalic) showed greater width of the hard palate. These results corroborate the theories presented by Vucic et al (2019) 2 and Miranda-Viana et al (2020) 3 that the bone structures of the craniofacial complex adapt to variations in craniofacial growth trends. Conversely, two previous studies reported no signi cant differences among facial types for linear measurements of the hard palate.…”

“…1,5 When there is an imbalance between the structures of the stomatognathic system due to airway obstruction, or due to changes in the direction of growth and development of the face, the hard palate may change and adapt its morphology, position, and function. 2,3,5 In this study, the dimensions of width and height of the posterior region of the hard palate in patients of different sexes, and skeletal and breathing patterns were assessed. It was also investigated if there was an association between the measurements of the hard palate and the volumes of the upper airways and maxillary sinuses.…”

“…1Studies in the literature have reported that the morphology of the hard palate may be in uenced by the muscular tension, which can vary with the facial type, and skeletal and respiratory pattern of the individual. [2][3][4] The characteristic stretched and weaker musculature of dolichofacial and mouth-breathing patients, for example, exert less pressure on the bone tissues, leading to possible alterations in the development of the craniofacial complex, including the maxilla and the hard palate. [4][5][6] Given the central location of the hard palate and its close relationship with the nasal cavity, oral cavity, and maxillary sinuses, it is possible that changes in its morphology may also affect other structures of the stomatognathic system.…”

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

Thus, this study aimed to assess the dimensions of the hard palate and associate them with sex, and skeletal and breathing patterns. Also, to investigate if there is a relationship between these dimensions and the volumes of the upper airways and maxillary sinuses. Methods Two hundred and ninety-eight CBCT scans of patients were classified according to sex, and skeletal and breathing patterns.
