Abstract
The obscure location of the frontal sinus, anatomical variations, complexities and its proximity to delicate structures creates a problem during dissection and obstructs clear visualization. Hence, a clear understanding of the anatomy and drainage pathway of the frontal sinus is essential for successful surgical outcome. Analysis of samples to measure and study the drainage of the frontal sinus with respect to uncinate process, study of aggarnasi cells as present or absent and relevant linear and angular measurements to facilitate easy approach to the frontal sinus. Forty CT scans were analysed using the latest version of RadiAnt DICOM viewer in sagittal view. Twelve cadaveric skulls were dissected and measurements taken with a probe, protractor and scale. The radiographs showed pneumatizedaggarnasi cells in 88.75% of plates. The drainage pattern was anterior to the uncinate process in all plates. The sinus ostium diameter and angles measured were similar among sexes and on both sides. However, the distance from the frontal beak to columella and to nasal spine was statistically less in females. The cadaveric study resulted in slightly different values compared to radiographs especially regarding the ostium diameter and angle with nasal floor. The other values were comparable to similar studies. A large portion of literature regarding the anatomy of the frontal sinus are cadaveric studies. Studies collecting superior radiological data with uniform parameters should be conducted. Considering the variations in the available data, a meta‐analysis will help settle the problem.
