OBJECTIVE: To understand the etiology of chronic @entity1244 . METHODS: Ninety-one coronal CT scans of chronic @entity1244 were analysed with mutimedia software developed by the authors. Sinus CT images were scanned into multimedia computer and the subtle anatomic structures such as pneumatization of the middle turbinate, agger nasi cell, Haller's cell, @entity85 , @entity1177 , @entity4530 and so on were measured. The results were analysed by the statistical software SPSS. RESULTS: The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with @entity1 with normal frontal sinuses, the vertical diameters of agger nasi cells of @entity1 with frontal @entity1244 were larger(11.70 +/- 5.50 mm and 8.54 +/- 3.67 mm respectively, P < 0.01). Compared with @entity1 with normal maxillary sinuses, the Haller's cells of @entity1 with @entity1180 were larger (77.8% and 33.3%, P < 0.05) and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6 +/- 17.8 @entity202 and 41.6 +/- 12.6 @entity202 , respectively, P < 0.05). The deviation of uncinate process was one of the factors of @entity1180 . The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause @entity15294 . CONCLUSION: Some anatomic variations may play a role in chronic @entity1244 .
