INVESTIGATION OF THE RELATIONSHIP BETWEEN ANATOMICAL VARIATIONS OF SINONASAL REGION AND CHRONIC SINUSITIS IN CHILDREN
1Ankara Numune Eğitim ve Araştırma Hastanesi, KBB, Ankara, Turkey Introduction: To analyze the relationship between anatomic variations of the sino-nasal region and CS in children who underwent functional endoscopic sinus surgery (FESS).Material and Methods: Computerized tomography(CT) scans of68children who underwent FESSbetween 2010 and 2018 were evaluated retrospectively. Patients were categorized into two groups according to age (group 1: aged 8?12 years; group 2: aged >12 years).Each CT scan was reviewed for the presence of agger nasi cells, Haller's cells, paradoxical middle turbinate, and nasal septum deviations of >3 mm. Involved sinuses were determined after observing opacification or mucosal thickening on CT.
Results: The maxillary sinus was the most commonly involved sinus. Agger nasi cells were the most common variation and were observed in 55 children (80.8%).Concha bullosa (CB) was the second most common variant, observed in 38children (55.8 %). There were 17 (25 %) children with a nasal septum deviation of >3 mm. Paradoxical middle turbinates were noted in 18 (26.4 %) and Haller's cells were observed in 13 (19.1%) children. There was no statistically significant difference between groups 1 and 2 for agger nasi cells, CB, paradoxical middle turbinate, or Haller's cells. There was a statistically significant difference between groups1 and 2 for nasal septum deviation.
Conclusion: We found no significant differences between younger and older children in terms of anatomic variations of the sino-nasal region, apart from nasal septum deviation.
