- Abstract
The Onodi cell is defined as the posterior-most ethmoid cell. Haller cells are defined as infraorbital ethmoid cells. HRCT scanning provides excellent bone detail and accurate soft tissue mapping. The aim of this study is to know the prevalence of Haller cells and Onodi cells and to find variations in them on HRCT. Also to find co-relation between HRCT findings and Intra operative findings. A Hospital based prospective and cross-sectional study which included 30 patients above 15 years of age coming to ENT OPD with complaints related to sinonasal disease and polyposis;willing for HRCT followed by operative procedures. A total of 30 patients are included in the study. The mean age was found to be 38.70 ± 14.37. Prevalence of haller cells and onodi cells was 30% and 33.3% respectively. Statistical significance was found between association of haller cells with sinusitis. Intra-operative findings corresponded to 8 out of 9 HRCT findings (p-value = 0.001). We conclude that the actual prevalence of haller cell and onodi cell is best noted on HRCT-PNS and this holds a significant role in imparting thorough knowledge of the anatomical variations of PNS and hence preventing intraoperative complications due to presence of these variant cells.
