Abstract
location and variants. The measurement of Agger Nasi cell volume, frontal beak thickness, frontal recess and frontal isthmus length were performed using facial bone review of high kernel algorithm. Correlation between volume of agger nasi cell with frontal beak thickness, A-P length of frontal isthmus and frontal recess determined using Pearson correlation test. Results: ANC found in 131 out of 140 adult patients (93.6%). Mean ANC volume 434.48 with standard deviation of 256.63. For FB thickness, A-P length of FI & FR, mean are 6.24 (SD 1.61) mm, 7.06 (SD 2.92) mm and 4.95 (SD 2.97) mm respectively. No significant correlation found between volume of ANC with FB thickness, A-P length of FI and FR. Conclusion: Thickness of FB did not correlate with volume of ANC and no significant correlation with A-P length of FI & FR with volume of ANC.
