Cone Beam Computed Tomographic Evaluation of the Maxillary Sinus in Different Craniofacial Patterns

Abstract

Objectives: Evaluation of maxillary sinus dimensions and volume and correlation with different craniofacial patterns.Methods: This study was done on 67 maxillofacial CBCT scans. Cases were classified skeletally according to Jarabak's ratio, into 3 groups: normal, hyperdivergent / long facial pattern, and hypodivergent / short facial growth pattern. Maxillary sinus dimensions were analyzed as sinus height, width, depth, and volume. All data were collected and statistically analyzed.Results: There was a statistically significant difference between the three craniofacial groups regarding the height and the width of the maxillary sinus, while sinus depth and volume were statistically non-significant. The correlation between maxillary sinus dimensions with the three craniofacial types was of very weak strength so statistically non-significant. Group 2 (hyperdivergent growth pattern) had statistically significantly lower mean height value and higher mean width value than the other two groups. The difference between the mean height values of group 1 (Normal growth pattern) and group 3 (hypo-divergent growth pattern) was statistically nonsignificant. The difference between the mean width values of group 2 and group 3 was statistically almost significant. There was no statistically significant difference in depth or volume between either of two groups. Conclusion:While comparing maxillary sinus dimensions with the craniofacial patterns, sinus height and width are statistically significantly different, while sinus depth and volume are statistically non-significant. However, there is a weak Correlation between maxillary sinus dimensions and the craniofacial patterns.
