Abstract:
OBJECTIVE:To study the anatomical character of the ethmoid sinus with spiral CT, and provide correlated data for diagnosis and surgery operation.
METHOD:One hundred patients whose vertebra artery was injected with Angiografin underwent axial consecutive computed tomography and these data were studied with multiplanar reformation.
RESULT:Based on the relation of posterior ethmoid sinus to sphenoid sinus, the posterior ethmoid sinus was divided into antero sphenoid types and super sphenoid types. According to the relation between the posterior ethmoid and the optic canal, the posterior ethmoid sinus was divided into antero canal, seminal abut types, canal abut types. According to the degree of the bulging of the optic canal, the posterior ethmoid sinus was divided into notch types, seminal cover types, canal cover types. Bulging of the optic canal formed on the lateral wall of the posterior ethmoid sinus was 40 sides (20%).
CONCLUSION:MPR in spiral CT is powerful tool for the anatomical study of the ethmoid sinus, it could provide accuracy evaluation and analyzation, these results are helpful in directing the diagnose and therapy.
