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。
The 50 Chinese adult bone sella and its surrounding bony structure were observed. The results showed that 6 patients in the anterior cotyledon and mid-coticular pedicles accounted for 6% of 100 patients. The saddle tubercle and the optic nerve crossing were significantly and slightly prominent in 38 cases (76%) in 50 cases. The saddle back is of different shapes, but its upper half is inclined forward. The cotyledon and the anterior cot healing and proximal healing were 3% in 3 cases. The anteroposterior diameter, width and depth of the measurement sella were 1.16±0.13, 0.99±0.16 and 1.29±0.15 cm, respectively. The bottom wall of the 30 cases of the pituitary fossa of the skull was 0.4-0.9 mm in thickness with an average thickness of 0.6±0.01 mm. These data provide a morphological basis for the clinical diagnosis of sellar lesions.
