【摘要】 对国人50例成人骨性蝶鞍及其周围骨性结构作了观测。结果为前床突和中床突愈合者6例占100例的6％。鞍结节与视神经交叉沟显著和稍显者38例占50例的76％。鞍背形态不一,但其上半部均向前倾斜。后床突与前床突愈合与接近愈合者3例占3％。测量蝶鞍的前后径、宽和深度分别为1.16±0.13、0.99±0.16和1.29±0.15cm。30例颅骨垂体窝的底壁,厚度为0.4～0.9mm,平均厚为0.6±0.01mm。这些数据为临床诊断蝶鞍区病变提供了形态学依据。更多还原

【Abstract】 The sphenoidal saddle and it’s peripheral structure of 50 Chinese adult skulls were observed and measured. If was found that the fusion of the processus clinoideus anterior and the processus clinoideus medius amourted to 6% of the 100 cases; that the appearances of the tuberculum sellae and the sulcus chiasmatis which were clear or fairly clear mack up 76% of the 50 cases; that the dorsum sellae varied in form but the upper half of the dorsum sellae was oblique to the anterior; and that the fused or nearly fused processus clinoideus anterior and the processus clinoideus posterior was 3%. The diameter from the anterior to posterior, width and depth of the sphenoidal saddle were 1.16±0.13, 0.99±0.16 and 1.29±0.15 cm respectively. The average thickness of the bottoms of the fossa hypophyseos was 0.6± 0.01mm. The data provide marphological basis for the clirical diagnosis of the diseases in the sphenoidal saddle area.更多还原
