Abstract

Objective

The superior attachment of the uncinate process and the agger nasi cell are important landmarks in frontal sinus surgery and are in close relation with each other. The aim of this study is to investigate the relationship between the two.

Study design

A retrospective radiological study.

Materials and methods

A total of 50 patients with features of chronic sinusitis were evaluated radiographically, i.e., by computed tomography. Hundred sides, i.e., 50 scans, were evaluated for superior attachment of the uncinate process and the presence of agger nasi. Chi-square test was used as a statistical tool for eliciting the relationship between the two.

Results

The agger nasi cell was found in 68 (68%) of 100 sides. The prevalence of agger nasi cell according to the superior attachment of uncinate process types was 64.1% for lamina papyracea, 79.41% for skull base, and 53.84% for middle turbinate. The presence of agger nasi cell according to the superior attachment types of uncinate process was not statistically significant (X2 = 3.5925, p = 0.16592).

Conclusion

The agger nasi cell was found in 68 sides (68%), and there was no statistical significance between the superior attachment of the uncinate process and the presence of agger nasi cell.
