Abstract

Aim & Objectives: To assess the dimensions of hard palate, volumes of maxillary sinus and upper airways in three different age groups and to gender. Materials And Method: 60 CBCT volumes acquired from the dental archives were used. Using Planmeca Romexis software, posterior width of the Hard palate is measured by drawing a line connecting the palatal cortical bone at the roots of the first molars of the right & left sides and of the first premolars. A perpendicular line drawn from the highest point of hard palate to the center of the horizontal lines determine the height of the hard palate. Using ITK SNAP software, the volumes of Maxillary sinus and upper airways is measured. Estimation of the upper airway space will limit to the level of C3. Results: Intergroup comparison performed using “One way ANOVA test” revealed a statistically difference between age groups for width of hard palate at molar (p=0.033) and premolar level (p=0.024) as well as volume of maxillary sinus on the right (p=0.023) and left side (p=0.005). Intergroup comparison performed using “One way ANOVA test” revealed a statistically difference between facial types for volume of maxillary sinus on the right and left side (p
