Abstract
Objectives: Endoscopic frontal sinus surgery is perhaps, one of the most complex procedures in the endoscopic sinus surgery, due to its anatomical location and the multiple anatomical variants that can be found. It is essential to know in detail the anatomy of this region in order to obtain a better understanding for the surgical planning. Currently, the frequency of these anatomical variations remains unknown in our country. Therefore, the objective of the study is to evaluate the frequency of the anatomical variants of the frontal sinus and to carry out a radio-anatomic study in a sample of patients from Colombia.
Study design: Observational, cross-sectional descriptive.
Methods: Randomized sample of 406 CT scan of the paranasal sinuses that included 812 frontal sinuses collected during the year 2018.
Results: The supra bulla cell was the most frequently reported with a frequency of 59.61%. The second cell was the supra agger (57.88%) followed by supra agger frontal cell (25.12%), supra bulla frontal cell (22.17%), supraorbital ethmoid cells (34,98%) and frontal septal cell (24,14%) . The anterior ethmoidal artery was found hanging in 31.28% and the most frequent AP diameter was between 5 -10 mm.
Conclusions: To perform an appropriate endoscopic frontal sinusotomy, it is necessary to know in detail the anatomy of the frontal sinus recess. The different radio-anatomical variants of the frontal sinus are very frequent in the population group studied. We believe that this study will allow surgeons to obtain a better understanding of this anatomical region of difficult surgical access.
