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

Table 1 Definitions of variables in the classification of individuals regarding skeletal patterns (skeletal malocclusions and facial types)

Skeletal pattern	Variables	Definition
Skeletal malocclusion	SNA	Angle formed from the points Sella (S), Nasion (N) and A
	SNB	Angle formed from the points Sella (S), Nasion (N) and B
	ANB	Angle formed from the points A, Nasion (N) and B
Facial type	Facial depth	Angle formed by intersecting the lines Po (Porion)—Or (Orbitale) and N (Nasion)—Pog (Pogonion)
	Facial axis angle	Angle formed by intersecting the lines N (Nasion)—Ba (Basion) and Pt (Pterygoid Point)—Gn (Gnathion)
	Lower facial height	Angle formed by intersecting the lines Xi (Geometric center of the ramus)—ANS (Anterior nasal spine) and Xi (Geometric center of the ramus)—Pm (Suprapogonion)
	Mandibular plane angle	Angle formed by intersecting the lines Go (Gonion)—Me (Menton) and Po (Porion)—Or (Orbitale)
	Mandibular arch	Angle formed by intersecting the lines Dc (Point in the center of the mandibular condyle)—Xi (Geometric center of the ramus) and Xi (Geometric center of the ramus)—Pm (Suprapogonion)
