Abstract
Aims: The study aims to investigate the normal dimensions of the frontal sinus and determine the role of the frontal sinus in various skeletal malocclusions and also to analyze the relationship between the length of the mandible and frontal sinus dimension. Materials and Methods: A total of 120 lateral cephalograms were selected according to the criteria and were grouped mainly into three groups: Group 1 – Class I (N = 40), Group 2 – Class II (n = 40), and Group 3 – Class III (n = 40). These were traced and analyzed by recording the linear measurements such as maximum width, maximum height, area of frontal sinus region, and the length of the mandible. To compare the difference between the skeletal classes, one-way ANOVA test was performed followed by post hoc with Sidak and Bonferroni statistical tests. Results: There was no such significant difference in the measurements of maximum width, height, and area of frontal sinus region of classes I, II, and III. Conclusions: After analyzing the linear dimensions, we found out that there is a significant difference in height, width, and area of the frontal sinus region with respect to classes I, II, and III. Therefore, we can say that the frontal sinus plays a significant role in depicting skeletal malocclusions.
