Introduction: Due to the fact that the prevalence of Haller's cells had not been investigated in Kashan city, this study aims to investigate the prevalence of Haller's cells and its relationship with the increase in the thickness of the maxillary sinus mucosa in patients referred to a private oral, maxillofacial radiology clinic in city of Kashan Done.

Materials and Methods: This descriptive-analytical study is based on 183 images taken using cone beam tomography (CBCT) imaging of patients who have referred to a specialized clinic for surgery on impacted wisdom teeth, examination of maxillary sinuses, and implantation in the maxilla were done. The images were checked for the presence and absence of Haller cells and the thickness of the maxillary sinus mucosa. The results were entered into the SPSS22 software and analyzed and statistically analyzed. The descriptive characteristics of the samples were determined using central and dispersion indices (mean-index deviation-frequency). To perform analytical analysis Chi Square test and Fisher test were used if necessary, and P ˂ 0.05 was considered significant.

Findings: According to the present study, the prevalence of Haller cells was reported to be 72%, and 89.5% of Haller cells were bilateral and 10.5% of them were unilateral. A significant relationship was observed between the prevalence of Haller's cell and gender, and more cases were related to women. However, there was no significant relationship between the prevalence of Haller cells and age. The prevalence of maxillary sinus mucus thickness (sinusitis) was reported to be 79%, and a significant relationship between the prevalence of Haller cells and the increase in maxillary sinus mucus thickness was observed, so that in 84% of samples with Haller cells, an increase in maxillary sinus mucus thickness was observed.

Conclusion: In the studied population, Haller's cell had a high prevalence, which was bilateral in most cases. According to the present study, a significant relationship was observed between the prevalence of Haller's cells and the increase in the thickness of the maxillary sinus mucosa, and the presence of Haller's cells along with its variations can be reported as one of the causes of sinusitis.
