Prevalence and variation of haller’s cells on cbct images and its correlation with maxillary sinus pathologies

Objectives: To evaluate size, shape, number of Haller’s cells and its correlation with maxillary sinus pathologies, nasal septum deviation. Study Design: 56 full FOV CBCT scans were retrospectively analysed. All the CBCT scans were obtained from same CBCT centre over a period of 6 months. Size of Haller’s cells were measured by measuring the maximum mesiodistal diameter on coronal slices of CBCT scans bilaterally. All the above scans were then analysed. Maxillary sinus pathologies were categorised as Mucosal thickening, Poypoidal thickening, Opacification. Results: Chi square test was used for statistical analysis to evaluate the correlation between the presence of Haller’s cells and Maxillary sinus pathologies. And was found to be stastically significant. (p<0.05) Conclusion: We conclude that Haller’s cells can be considered as an important contributing factor for maxillary sinusitis.
