Introduction
Albert von Haller described Haller cells (HC) as anterior ethmoidal cells along orbital floor and above maxillary sinus ostium. Location of HC could predispose maxillary sinusitis (MS)
Purpose of the Study
Determine prevalence of HC and relationship of size-based HC with MS and orbital floor dehiscence (OD) in CBCT.
Materials and Methods
Fifty 9” FOV CBCT volumes evaluated for HC. CBCT images were acquired in Section of OMFR UCONN Dental Medicine. Images were evaluated for presence of HC and association with MS and OD .Both HC and sinuses ostia were categorized small, medium, and large.
Chi-square and Cochran-Mantel-Haenszel tests were used for statistical analysis and P-values >0.05 were considered to be statistically significant.
Results
Out of 50 patients HC were in 30 patients (60%) 17 were bilateral 13 unilateral. HC with MS were in 27 patients. Small-sized HC was evident in 13 patients, medium in 10 and large in 24 respectively. Small maxillary sinus ostia were 26, medium 12 and large 9 respectively .OD were evident in 23 on right and 24 patients in left respectively.
There was no statistically significance between HC, size of HC, size of maxillary sinus ostium with MS. HC and OD showed strong statistically significance.
Conclusion HC prevalence was high. No association of HC between presence, size and MS could indicate that MS is primary condition than resulting from narrowing of maxillary sinus ostia. HC is an indicator of OD. Case-control studies are recommended to investigate the relationship between HC and MS.
