| Summary: | Introduction: Lateral cephalograms are routinely used in
orthodontics for accurate assessment and treatment planning
of malocclusion. Paranasal air sinuses, such as the maxillary
and frontal sinuses, are visible in the lateral cephalogram.
However, a direct correlation between the area of these sinuses
and the tendency to develop skeletal discrepancies has not
been studied in the literature.
Aim: To determine the cephalometric correlation between
different skeletal malocclusions and the dimensions of the
frontal and maxillary sinuses.
Materials and Methods: A cross-sectional cephalometric
study was conducted at a Tertiary Care Centre in Siliguri district
of West Bengal, India. The duration of the study was two years,
from August 2019 to September 2021. A total of 150 patients
were included and they were divided into three equal groups:
skeletal class I (n=50), skeletal class II (n=50), and skeletal
class III (n=50). Multiple cephalometric parameters were traced
on the radiographs using Dolphin and AutoCAD software, and
they were compared among the three groups. The data were
analysed using Pearson’s correlation test.
Results: The results showed a statistically significant correlation
between Maxillary Sinus Area (MSA) and Gonial angle (r=0.468,
p=0.001) in skeletal class I malocclusion. In skeletal class II
malocclusion, a significant negative correlation was found
between Frontal Sinus Area (FSA) and total mandibular length
(r=-0.30, p=0.009). However, no significant negative correlation
was found between MSA and any cephalometric parameter in
skeletal class II malocclusion.
Conclusion: The present study highlights there was an increase
in the size of the maxillary and frontal sinuses was observed in
skeletal class II and skeletal class III malocclusion. However, no
correlation could be found between skeletal class I malocclusion
and the areas of the frontal sinus. |
