A study of sinonasal anatomy and its variations in chronic rhinosinusitis patients

Background: Nose and paranasal sinuses have wide range of anatomical variations that are best diagnosed by the computed tomography (CT) and diagnostic nasal endoscopic examination. Aims and Objectives: This cross-sectional study was done to evaluate the incidence of anatomical variations in patients of chronic rhinosinusitis (CRS) and its correlation with these anatomical variations. Materials and Methods: One hundred subjects attending the outpatient department of ENT at Rajindra Hospital, Patiala, were enrolled in the study. These subjects were diagnosed to have CRS (with either one major, two minor, or two major symptoms of CRS according to the TASK FORCE criteria). All patients were assessed using diagnostic nasal endoscopic examination and CT scan. Results: The anatomical variation that was found to be significant in the causation of CRS was deviated nasal septum (P = 0.042) and concha bullosa (P = 0.0003), which were highly significant. Conclusion: In the present study, correlation between deviated nasal septum and concha bullosa with CRS was significant statistically.
