Abstract

Objectives: The study was carried out to evaluate the dimensions and volume of maxillary sinus along with its distribution among different sagittal and vertical skeletal facial types.
Materials and Methods: A sample of 90 patients was segregated into three sagittal groups based on ANB angle which was further subdivided into three vertical subgroups based on SN-GoGn angle using NNT software. The volumetric assessment was carried out usingHoros software while the linear measurements were performed on CBCT images analysed in NNT software. The inter-group statistical comparison of means of continuous variables was done using Analysis of Variance (ANOVA) with Bonferroni’s multiple group comparisons.
Results: The maxillary sinus volume did not differ significantly across different sagittal and vertical skeletal patterns, the mean sinus volume being 13.08 (+/- 5.38) cu mm among the study population. The maxillary sinus length in Class I skeletal pattern was 3.65 cm (Hyperdivergent group), 3.64 cm (normodivergent group) and 3.52 cm (Hypodivergent group).
Conclusion: The distribution of maxillary sinus dimensions did not differ significantly across the different skeletal and vertical facial types. The only statistically significant finding was the greater maxillary sinus length in all three types of vertical skeletal patterns of Class I as compared to Class III malocclusion.
