Abstract
Objective To observe the cells of frontal recess region with multi-detector CT muhiplanar 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. Key words: Frontal sinus; Tomography; X-ray computed
