Anatomical variations in sinus imaging in sinusitis: a case control study. Objective: To compare anatomical variations in sinusitis patients and control subjects.
Subjects and methods: We reviewed and compared the computed tomography (CT) scans of 87 sinusitis patients after adequate medical treatment and scans of 103 healthy subjects. All images were scored for sinusitis severity using the Lund-Mackay scoring system. Anatomical variations such as septal deviation, concha bullosa, presence of the Haller’s cell, paradoxical middle turbinate, prominent agger nasi cell, and Onodi cell were also recorded.
Results: Of the 190 evaluated CT images, 55.2% of the cases and 47.6% of the controls had septal deviation (p > 0.05). The prevalence of concha bullosa was 68% in patients and 61% in controls (p > 0.05).
Conclusion: There were no significant differences in the evaluated anatomical variations between cases and controls in this study. Mucosal inflammation may play a more essential role than anatomical variation in the development of sinusitis.
