Abstract
Background There are variations of frontal cells in different populations, and the usefulness and applicability of the new frontal sinus classification in our population need further study. Hence, we aimed to study the International Frontal Sinus Anatomy Classification (IFAC) in our patients with chronic rhinosinusitis (CRS) and determine the association of the frontal cells with the development of frontal sinusitis. In addition, the relations of frontal cells variants with severity of frontal sinusitis was studied. Methods This was a retrospective chart review on computed tomography paranasal sinus (CTPNS). A total of 200 patients who had clinical and endoscopic findings suggestive of CRS and undergone CT paranasal sinuses and plus 51 patients as control was reviewed and the prevalence on frontal cells variants were analyze based on IFAC. Results Five hundred two sides of CTPNS was reviewed and showed the agger nasi cells was mostly found (95.8%) followed by supra bulla cell (59.8%) , supra bulla frontal cell (54.8%), supra agger cell (48.6%), supra agger frontal cell (33.1%), frontal septal cell (8.6%) and supraorbital ethmoidal cell (4.6%). Conclusion Patients with the presence of supraorbital ethmoidal cell (SOEC) and frontal septal cell (FSC) are more significant in developing frontal sinusitis (p value <0.05). Posterior and medial cells play more role in causing frontal sinusitis. IFAC is useful in identifying the cells responsible for causing frontal sinusitis. It may help in guiding the surgeon to remove the cells in preventing recurrent disease.
