Study of the cells of frontal recess region with multi-detector CT multiplanar reconstruction and clinical significance

Objective: To observe the cells of frontal recess region with multi-detector CT multiplanar reconstruction(MPR). Methods: One hundred patients without the disease of frontal sinus and frontal recess region underwent axial multi-detector CT scan with axial, coronal and sagittal multiplanar reconstruction. Results: In 100 cases(200 sides), the agger nasi cell is present in 186 sides(93.0%), the frontal cells were identified in 88 sides (44.0%), the prevalence of type I, type II, type III and type IV cells were 51 sides (58.0%), 23 sides (26.1%), 14 sides (15.9%) and 0 sides, respectively. The suprabullar cells, the frontal bullar cells and the supraorbital ethmoid cells were identified in 130 sides (65.0%), 23 sides (11.5%) and 11 sides (5.5%), respectively. The interfrontal septal cells were identified in 36 sides (18.0%). There was no significant difference between males and females, as well as between left and right side (P>0.05). Conclusion: With MPR imaging, doctors could better understand the frontal recess region, which is helpful to the endoscopic frontal sinus surgery. (authors)
