摘要
对１００例正常成人冠状位ＣＴ影像进行观察测量，筛板宽度均值为：男８．０７±１．４１ｍｍ，女：７．４７±１．３０ｍｍ；筛板外侧板高度均值为４．１２±１．８０ｍｍ。根据其与筛板的夹角测量陡直型为９７．０９±８．４２°；缓坡型为１３９．５１±１０．２６°。筛前孔的骨管样筛前孔为２６．０％，锥孔样筛前孔为６２．０％。探讨了筛板、筛板外侧板及中鼻甲根部之间的关系和形态特征，为预防鼻内窥镜手术并发症的发生提供影像解剖学资料。
Abstract Coronal CT images of paranasal sinus in 100 normal a6ults were selected to study the cribriform plate and adjacent structures.There were 61 males and 39 females ranging in age from 18 to 56 vears.The results showed that:(1)The means values of width of the cribri-form plate are 8.07±1.41mm in males,and 7.47±1.30mm in females.(2)The means val-ues of lemgth of the lateral lamella of lamina cribrosa are 4.12±1.80mm,They were divided into two types according to the angle between the cribriform plate and the lateral lamella of lamina cribrosa:the precipitous type has an angle of 97.09±8.42;and the tardo type hasan angle of 139.51±10.26.(3)The antericr ethmoid foramen are classified into two types,the canallike and the conelike anterior ethmoid foramen.The anatomical relationships and morphologic features of the cribriform plate,the lateral lamella of lamina cribrosa and the middle nasal turbinate also were discussed
