ABSTRACT BACKGROUND The term ‘rhinosinusitis’ is defined as inflammation of the mucosa of the nose and paranasal sinuses. Anatomical variations are predisposing factors for causing rhinosinusitis. A precise knowledge of the anatomy of the paranasal sinuses is essential for the clinician. With the advent of Functional Endoscopic Sinus Surgery (FESS) and Coronal Computed Tomography (CT) imaging, considerable attention has been directed toward paranasal region anatomy. Remarkable anatomic variations of nasal septum and lateral of nose region and their possible pathologic consequences should be well defined in order to improve success of management strategies and to avoid potential complications of endoscopic sinus surgery. The objective of this study is to determine the anatomical variations leading to clinical sinusitis and to compare them with normal population. The aim of this study is to analyse the relationship of anatomical variations and rhinosinusitis. MATERIALS AND METHODS It is a descriptive study. Patients admitted in our hospital from 1/1/2016 - 31/7/2017 with symptoms of sinusitis were randomly selected and considered for CT paranasal sinuses for detection of any anatomical variations. Design- This is a case control study. A prospective study of 200 patients was done on the CT scans of patients with clinical sinusitis. RESULTS Anatomical variations leading to sinusitis were Concha Bullosa (43%), Deviated Nasal Septum (34.6%), Agger Nasi (41.12%), Haller Cell (10.28%), Paradoxical Middle Turbinate (10.28%), Large Bulla (7.48%), Onodi Cell (5.61%) and Pneumatised Uncinate (2.8%). CONCLUSION It was concluded that the anatomical variations play a significant role in rhinosinusitis and prior CT PNS is essential for diagnosis and treatment.

Remarkable anatomic variations of nasal septum and lateral of nose region and their possible pathologic consequences should be well defined in order to improve success of management strategies and to avoid potential complications of endoscopic sinus surgery. Currently, CT scanning is the standard imaging in the evaluation of the paranasal sinuses. This, combined with endoscopy, gives an applied anatomical view of the region and of the anatomical variants that are often found. ‘Financial or Other Competing Interest’: None.

MATERIALS AND METHODS The present study is a descriptive study of anatomical variations in clinical rhinosinusitis, was carried out in the Department of ENT, Great Eastern Medical School and Hospital, Ragolu, Srikakulam. Patients admitted in our hospital from 1/1/2016 - 31/7/2017 with symptoms of sinusitis were randomly selected for the study. Rhinosinusitis- Symptoms/ Signs Major Minor Facial pain/pressure Headache Facial congestion/fullness Fever (Non-acute) Nasal obstruction/blockage Halitosis Nasal discharge/purulence/ discoloured Fatigue Hyposmia/anosmia Dental pain Purulence on nasal examination Cough Fever (Acute RS only) Ear pain/pressure/fullness Requires 2 major factors or 1 major and 2 minor factors.
