Intra-observer consistency: Repeated CT measurements
indicated no significant intra-observer difference for the first
observer (p > 0,05). Overall intra-observer consistency was
rated at 88.4% between the two evaluations and measurements. All
measurements were found to be highly reproducible for both observers and
no significant difference obtained from two measurements of the
observers (p > 0,05). Thus, the mean values of all
measurements were included in the statistical analysis.
Differences between the two groups for variables are presented in Table
1, and differences between left and right maxillary sinuses, separately
for the two groups are presented in Table 2. Statistically significant
results were obtained between groups for ethmoid and maxillary sinus
volumes (left and right). Ethmoid and maxillary sinus volumes (left and
right) were smaller in the Le Fort group. No statistically significant
differences were present for sphenoid sinus volume of two groups. Left
and right maxillary sinus volumes did not vary in the total study group.
The presence of Onodi cells did not vary between groups.
