Role of CT Imaging to Evaluate Osteomeatal Complex in Inflammatory Lesions of Paranasal Sinus

The osteomeatal complex or unit is the region where the frontal, anterior and middle ethmoid and maxillary sinuses drain. This includes the frontoethmoidal recess, uncinate process, hiatus semilunaris, ethmoid bulla, the maxillary infundibulum and ostium along with the ethmoid infundibulum.It may be normal, blocked or widened in different inflammatory conditions of PNS.CT scanning is of prime importance because it is helpful in evaluation of osteomeatal complex in different inflammatory conditions of PNS.50 cases of either strong suspicion or diagnosed of inflammatory conditions of PNS were evaluated.A detailed clinical history with clinical examination and follow up of the suspected/ proven cases was done by CT scan.CT imaging was performed using continuous spiral scan of Paranasal Sinuses with I.V. contrast.
