Abstract :

Introduction: Facial pain syndrome is a headache secondary to mucosal contact points in the sinonasal cavities. This headache may also result due to anatomical variations. These variants may determinate contact points between nasal structures, stimulating “trigger” points and determining facial pain crisis. Aims and Objectives: The aim of this study is to assess the prevalence of anatomical variations – concha bullosa, Haller cells, Agger nasi cells and Onodi cells. Materials and methods: Data comprised paranasal sinus computed tomography images of 50 patients (25 males and 25 females) that were retrieved from archives and analyzed for presence of anatomical variations, such as concha bullosa and air cells – Agger nasi cell, Haller cell, and Onodi cell. Data obtained were analyzed with Chi–square test and Mann–Whitney test. Results: The highest incidence was seen in Agger nasi cells (64%) followed by concha bullosa (62%), Haller cells (54%), and Onodi cells (36%). We found no statistical significance when compå the relationship of anatomical variations with age, side, and gender.
