Purpose
The aim of this retrospective research is to compare frontal sinus dimensions in
skeletal Class I, skeletal Class II, and skeletal Class III individuals and to evaluate
the relationship of these dimensions with anterior skull base length and some
cephalometric values.
Materials and Methods
In this research, we used lateral cephalometric radiographs of 60 people aged 17 to
25. In individuals with skeletal Class I malocclusion, skeletal Class II malocclusion due
to mandibular insufficiency, and skeletal Class III malocclusion due to mandibular
excess, measurements of frontal sinus length and height as well as S-N, Co-A and CoGn lengths, ANB0
, FMA0
, SN-GoGn0
angles values were performed. The length between
the highest point and the lowest point of the frontal sinus was calculated as the height
of the frontal sinus, and the length between the most anterior and the most posterior
points of the frontal sinus was calculated as the length of the frontal sinus.
Results
The frontal sinus length and height were found to be higher in skeletal Class III
individuals than in skeletal Class I and skeletal Class II individuals, however, there
was no significant difference between skeletal Class I and Class II individuals.
Conclusion
The increase in frontal sinus height and length correlated positively with the
decrease in the ANB angle and the increase in the SN and Co-Gn lengths. The
dimensions of the frontal sinus may be an indicator for the remaining mandibular
growth potential.
