Comparative analysis of dimension of frontal sinus with different skeletal patterns
Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH - Year 2016, Vol 8, Issue 12
Abstract
Objective: The aim of the study was to investigate the normalcy of the dimensions of frontal sinus and compare the relationship of the frontal sinus with the different skeletal malocclusion and also to find a relationship between the length of the mandible and the dimensions of the frontal sinus. Materials and Methods: A total of 60 pretreatment digital lateral cephalograms were selected according to the criteria and grouped into 3 groups, group 1: Class I (n=20), group 2: Class II (n=20) and group 3: Class III(n=20). Lateral cephalograms were traced and analysed on basis of frontal sinus i.e. the following linear measurements were recorded: maximum height, maximum width, area of frontal sinus region and the length of the mandible. Statistical Analysis: One-way ANOVA test was performed to compare the difference between the skeletal classes. Multiple comparison test was performed with post hoc with Bonferoni and Sidak statistical tests were performed. Results: The linear measurements of maximum height, maximum width, area of frontal sinus region showed statistically insignificant differences in Class I, Class II, and Class III (p-vaule=0.16, 0.4 and 0.12 respectively). Conclusion: We observed there is a no significant difference between maximum height, width and area of frontal sinus with respect to Class I, Class II and Class III. Hence, we can say frontal sinus is not so reliable in depicting skeletal malocclusions.
