Title: Study of Ethmoid Sinus Variations by Multislice Spiral CT
Abstract: Objective To evaluate the significance of multislice spiral CT(MSCT) 3D reconstruction technique in showing anatomy of ethmoid sinus and the anatomic variations of ethmoid sinus. Methods Ethmoid sinuses of 250 cases were scanned transversally by MSCT with coronal and sagittal views were reconstructed. Results Views of Coronal and sagittal reconstruction were nearly the same with the view coronal and sagittal scanned. Five kinds of common ethmoid sinus variations were seen, including pneumatization of ethmoid bulla (104, 56.5%), Onodi air cell (48, 26%), Haller cell (12, 6.5%), low ethmoid foveolas (8, 4.3%) and over intromigratiny lamella papyracea (12, 6.5%). Conclusion The coronal and other special views of ethmoid sinus are shown clearly by 3D reconstruction which can provide detailed image information for endoscopic sinus surgery.
