Effect of Concha Bullosa on Skull Base
Journal Title: Istanbul Medical Journal - Year 2020, Vol 21, Issue 1
Abstract
Introduction: To demonstrate the effect of concha bullosa (CB) on the height of the skull base. Methods: We retrospectively scanned the files of 1022 patients who had undergone paranasal sinus tomography for sinusitis in our hospital. Three hundred thirty patients had bilateral, and 330 had unilateral CB, but 330 patients did not have CB. Patients with inappropriate sections and positions were excluded from the study. A total of 990 patients aged between 18 and 72 years were included in the study. Five hundred sixty-seven of the patients were female, and 423 were male. In each group, the heights of the right and left skull base of male and female patients were compared within themselves and between each other. The height of the skull base was measured in the coronal plane along the lateral lamella between the cribriform plate and the fovea ethmoidalis, and these measurements were classified as Keros classification. (Keros type 1: 1-3 mm, Keros type 2: 4-7 mm, Keros type 3: 8-16 mm). Results: There was no statistically significant difference in the comparison between right and left skull base heights of female and male patients in bilateral CB group. Also, there was no statistically significant difference between the comparison of women and men within themselves. There was a statistically significant difference between CB side and non-CB side skull base heights of female and male patients in unilateral CB group, although there was no statistically significant difference between the comparison of women and men within themselves. Conclusion: In patients with unilateral CB, there is skull base asymmetry between the sides of CB and non-CB, and this should be taken into consideration to prevent complications.
