Abstract

Introduction: Due to the possible association between chronic sinusitis and anatomical variations of the area, the present study was performed to determine the prevalence of concha bullosa and nasal septal deviation and their association with chronic sinusitis to increase the success rate of nasal endoscopic surgery by eliminating the predisposing factors.

Methods and Materials: In this cross-sectional study, CBCT images of maxilla from 100 patients referred to the radiology department of Hamadan Dental School in the year 2016-2017 were examined. Pneumatization of middle concha (concha bullosa) on sides, nasal septum deviation, and mucosal thickening were recorded. Data were analyzed by Chi-square test based on gender and age (p value ≤ 0.05).

Results: The results showed that there was no significant difference between the mean age and sex with the presence of concha bullosa (p value > 0.05). 50% of the samples had nasal septum deviation and 42% had chronic sinusitis displaying no significant difference between men and women (p value > 0.05); Also, there was no significant difference between nasal deviation and chronic sinusitis (p value > 0.05), although chronic sinusitis was significantly higher in people with concha bullosa and while concha Bullosa was significantly higher in people with nasal septal deviation (p value < 0.05).

Conclusion: According to the results of the study, concha bullose can be considered as a predisposing factor for chronic sinusitis.
