Anatomical Variations in Nose and Paranasal Sinuses in Patients Presenting with Chronic Rhinosinusitis

Abstract

Introduction: The anatomy of organs of ENT is a herculean task to understand and evaluate in the whole human anatomy. Knowledge about the possible variabilities is never complete, since there is always a scope to understand better and know more. Many studies have been undertaken in the past to understand better the already existing knowledge about the various anatomical details in the nose and paranasal sinuses causing chronic rhinosinusitis. The present study was carried to know the details of variations in anatomy of nose and paranasal sinuses causing chronic sinusitis. Material and Methods: A Cross sectional study conducted over a period of two years, in patients presenting to ENT OPD with symptoms and signs and chronic rhinosinusitis, in a setting of tertiary hospital, with the requisite investigative protocols. Patients meeting the inclusion criteria were included in the study and subjected to the prescribed interventions. Results: Observations gathered from this study are-of the 65patients included, 86.1% had septal deformities, 58.4% had Concha bullosa, 52.3% had Agger Nasi, 15.3% had Haller Cell, 13% had Paradoxical Middle Turbinate, 4.6% had Everted Uncinate Process, 3% had Enlarged Bulla. Conclusion: Sinonasal anatomy is different in each individual, with various combined variations also.

“…Study from Rashi and Tapendra showed that the highest variation was a septal deviation, followed by concha bullosa [23], [24]. Lakshmipathi in the study found 86.1% had septal deformity, 58.4% Concha bullosa, 52.3% Agger Nasi, 15.3% Haller Cell, 13% Middle Turbinate Paradox, 4,6% had everted uncinate process, and 3% had bulla enlargement [25]. Nitin found septal deviation was the most common anatomic variation in 59 patients (48.30%) on nasal endoscopy and 62 patients (50.81%) on computed tomography [14].…”
