Analysis of relationship between Haller cells and Schneiderian Membrane Thickness

Abstract

Objective: This first aim of this study was to determine whether there is a relationship between the presence of Haller cells and Schneiderian membrane thickness (SMT) by considering factors such as age and gender. The second aim of this study was to investigate correlation between the visibility of Haller cells on cone beam computed tomography (CBCT) and digital panoramic radiographs. Materials and Methods: Seventy-eight edentulous patients were included in the study. Cross-sectional views obtained from CBCTs were used to determine the mean sinus membrane thickness. Parameters such as gender and age were also investigated. Results: The difference in SMT at the base of the maxillary sinus was significant between those with and without Haller cells (p <0.05). A correlation was found between the detection of Haller cells on CBCT and digital panoramic radiographs (p <0.01). Although SMT was higher in men than in women, this difference was not significant (p> 0.05). Conclusion: Considering the results of our study, the presence of Haller cells may cause sinus membrane thickness at base of maxillary sinus. Since Haller cells can also be seen in digital panoramic radiographs, digital panoramic view taken prior to sinus lift surgery can provide clinicians with preoperative hint about SMT.
