目的 :为临床颅内占位性病变的诊断提供依据。方法 :随机选取成年头颅侧位 X线平片 ,对鞍背厚度 ,鞍结节形态及角度 ,蝶鞍形态、前后径及深径进行观测。结果 :鞍背厚度为 5 .0 9± 1.13mm;鞍结节形态常见型 93.5 % (2 46例 )、锐利型 1.2 %(3例 )、平坦型 1.2 % (3例 )、垂直型 2 .3% (6例 ) ,鞍结节角度 12 5 .6 4°± 11.97°;蝶鞍形态为椭圆形的占 88% (2 2 7例 ) ,圆形的占8.1% (2 1例 ) ,扁平形的占 3.9% (10例 ) ,蝶鞍前后径 11.7± 2 .31mm ,深径 9.5± 1.6 9mm。结论 :所测结果可作为国人正常 X线解剖数据标准
Objective: To provide evidence for clinical diagnosis of intracranial space-occupying lesions. Methods: The adult skull radiographs were randomly selected. The thickness of saddleback, the shape and angle of saddle nodules, the shape of the sella, the anteroposterior diameter and the depth of the saddle were observed. Results: The saddleback thickness was 5.90 ± 1.13mm. The common form of saddle nodule was 93.5% (2 46 cases), sharp type 1.2% (3 cases), flat type 1.2% (3 cases) and vertical type 2. (27 cases), 3% (6 cases), saddle nodule angle 12 5 .6 4 ° ± 11.97 °, 88% (227 cases) with round shape, 8.1% (21 cases) Flat shape accounted for 3.9% (10 cases), anteroposterior diameter of 11.7 ± 2.31 mm, depth of 9.5 ± 1.6 9mm. Conclusion: The measured results can be used as normal human X-ray anatomical data standards
