Influence of Superior Attachment of Uncinate Process on Presence of Agger Nasi

Abstract

ABSTRACT Objective The superior attachment of uncinate process and agger nasi (AN) 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 (UP) and presence of AN cell. Study design A retrospective radiological study. Materials and methods Fifty patients with features of chronic sinusitis were evaluated radiographically, i.e. computed tomo graphy (CT), 100 sides, i.e. 50 scans were evaluated for superior attachment of UP and presence of AN. Chisquare 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 accor ding to superior attachment types of UP was not statistically significant (χ2 = 3.5925, p = 0.16592). Conclusion The AN cell found in 68 sides (68%), and there was no statistical significance between the superior attachment of UP and presence of AN cell.
