Title: Influence of superior attachment of uncinate process on presence of agger nasi.
Objective: The superior attachment of uncinate process and agger nasi cell are important landmark in frontal sinus surgery, and are in close relation to each other. The aim of the study is to investigate the relationship between the superior attachment of uncinate process and presence of agger nasi cell.
Study Design: A retrospective radiological study.
Method: 50 patients with features of chronic sinusitis were evaluated radiographically i.e, Computed tomography. 100 sides i.e., 50 scans were evaluated for superior attachment of uncinate process and presence of agger nasi. Chi square test was used as statistical tool for eliciting the relationship between the two.
Results: The AN cell was found in 68 (68%) of 100 sides. The prevalence of AN cell according to superior attachment of UP types were 64.1% for lamina papyracea, 79.41% for skull base, 53.84% for middle turbinate. The presence of AN cell according to superior attachment types of UP was not statistically significant (χ2=3.5925, p=0.16592).
Conclusion
The agger nasi cell found in 68 sides (68%), and there was no statistical significance between the superior attachment of uncinate process and presence of agger nasi cell.
