Computerised Tomographic Evaluation of Structural Variations in Sinonasal Region and its Clinical Correlation
Journal Title: International Journal of Clinical & Experimental Otolaryngology (IJCEO) - Year 2017, Vol 3, Issue 5
Abstract
Introduction: The endonasal as well as paranasal anatomy is highly variable and can encroach upon the osteomeatal complex and narrow the osteomeatal channels. Aims And Objectives: To study on CT scan, the incidence of structural variations in sinonasal region and its correlation with sinusitis. Material And Methods: It’s a cross sectional study on 106 cases done over 1 year. Results And Observations: On the basis of clinical diagnosis chronic sinusitis was seen in 90 (84.9%) cases and gross polyposis in 16 (15.1%) cases. CT scan anatomical variations seen were as follows: Concha bullosa 64 (60.37%), aggernasi cell in 58 (54.7%), PMT in 28 (26.41%), Large ethmoidal bulla in 18 (16.98%), uncinate pneumatization in 12 (11.3%), haller cell in 18 (16.98%) and onodi cell in 12 (11.35 %) cases. Maxillary sinus was most commonly involved in 90 (84.9%) cases and least common involved was sphenoid sinus in 14 (13.2%) cases. Among the 5 different patterns of CRS on CT scan most common was OMC pattern noted in 32 (30.18%) cases followed by infundibular pattern in 31 (29.24%), sporadic or unclassified unit pattern in 25 (23.58%), sinonasal polyposis in 10 (9.43%) cases and SER pattern in 08 (7.54%) cases. Conclusion: Rhinosinusitis commonly affects working population with female preponderance. Anatomical variation is observed to be one of the predominant causes for OMC block as well as sinusitis and CT is the paramount modality to study and analyze them.
