Clinical relevance: Tomographic analysis of the maxillary sinus and associated anatomical structures, such as the nasal cavity, is the most reliable resource for planning and carrying out implant-supported rehabilitation of the maxilla posterior region.

That was a cross-sectional tomographic study of 58 totally edentulous adult patients, totaling 116 maxillary sinuses. The RadiAnt DICOM Viewer™ 2020.2 (64-bit) software was used to measure basal/alveolar widths and maxillary length, in addition to linear distances from the maxillary sinus and nasal cavity to calculate volumes. Results: There was no significant correlation between the maxillary sinus nasal cavity volumes (ρ=0.048 / p=0.609). The volume of the nasal cavity showed a significant difference between genders (p=0.007), bigger in males. Greater alveolar and basal maxillary widths correlated with greater maxillary sinus volume. Maxilla length was significantly correlated with nasal cavity volume (ρ=0.425 / p<0.001). Sinus membrane thickness was not significantly associated with maxillary sinus volume. There was no significant correlation between sinus thickness lateral wall and sinus membrane thickness.
