Objectives: In this study our purpose was to determine
the incidence of paranasal sinus anatomic variations and
their relationship with sinus opacities in pediatric patients.
Patients and Methods: A total of 44 children ranged
between 3 and 16 years of age unresponsive to maximum
medical therapy were evaluated with coronal paranasal
sinus computed tomography.
Results: Computed tomographic evaluations revealed
that 70.5% (31/44) of the patients had at least 1 anatomic
variation; the most common one was septal deviation, followed
by concha bullosa and agger nasi cells. Sinus opacities
were found in 81.8% (36/44) of the patients, of whom
9 had single and 27 had multiple involvement of sinus
groups. Most common involved sinuses were anterior ethmoids
and maxillary sinuses, followed by posterior ethmoids,
sphenoid and frontal sinuses. When we look at the
influence of anatomic variations on sinus opacities;
patients with single, multiple and no anatomic variations
had 78.9% (15/19), 83.3% (10/12), and 84.6% (11/13)
Conclusion: Incidence of anatomic variations was found
to be similar to that reported for adults in the literature;
except nasal septal deformity which was found lower than
adults. Our results revealed no correlation between bony
anatomic variations and sinus opacities in children.
