Radiological correlation between pneumatization of frontal sinus and height of fovea ethmoidalis
Abstract
Background: We need more data about the variations of skull base to minimize the complications of ethmoidectomy. The aim of this study was to analyze the relationship between the pneumatization of the frontal sinus and height of the fovea ethmoidalis. Methods: Paranasal coronal computed tomography (CT) scans of 487 sides of 300 patients were evaluated. The presence of the frontal cell and pneumatization of the frontal sinus were studied with respect to the height of the fovea ethmoidalis. Results: We found a statistically significant correlation between the frontal cell and frontal sinus hyperpneumatization (p = 0.000). We determined that there was a deeper fovea ethmoidalis in the sides that have a frontal cell (p <= 0.001) and in the sides that have hyperpneumatization of the frontal sinus (p = 0.000). We also observed flatter fovea ethmoidalis in the sides that have hypopneumatization of the frontal sinus (p <= 0.001). Conclusion: The presence of a frontal cell or hyperpneumatization of the frontal sinus on CT scan should alert the clinician that there may be a deep fovea ethmoidalis.
