The term sinusitis refers to a group of disorders characterised by inflammation of the mucosa of the paranasal sinuses. Anatomical variations are found to block the ostiomeatal complex and cause sinusitis. CT scanning is the standard imaging in the evaluation of paranasal sinuses.
MATERIALS AND METHODS
The present study was carried out in the Government ENT Hospital, Visakhapatnam, Andhra Pradesh and comprises of 107 cases of rhinosinusitis. The patients presenting with symptoms of sinusitis were randomly selected for the study.
The incidence of anatomical variations in CT scan study were- Concha bullosa ( 42.99%), Agger nasi cells (41.12%), Deviated nasal septum (34.60%), Paradoxical middle turbinate (10.28%), Haller cells (10.28%), Onodi cells (5.61%), Pneumatised uncinate (2.80%).
The high incidence of variations emphasises the need for proper preoperative assessment for safe and effective endoscopic sinus surgery.
