摘要
目的 :为肌圆锥间隙疾病及眼型 Graves病影像学诊断提供形态学基础。方法 :在 1 5个防腐固定成人尸头的颅前窝底上作 9个连续冠状断面 ,观测眼球后第 2~ 5断面眼直肌的宽、厚、断面面积和距离。结果 :在第 2~ 5断面上 ,眼直肌断面面积之和与相应眶断面面积的比率分别为 :( 2 0±3) %、( 2 7± 2 ) %、( 2 3± 3) %、( 1 3± 1 ) %。水平肌厚度之和与相应眶宽的比率分别为 :( 36± 4) %、( 39± 5 ) %、( 33± 5 ) %、( 2 4± 4) %。结论 :在第 3断层上利用此两个比值可预测眼型 Graves病视神经病变发生的可能性。眼眶冠状断面可反映眶内各间隙之间的关系 。
Objective:To provide morphological basis for imageologic diagnosis of diseases inside the muscle cone and Graves′ophthalmopathy. Methods: On the anterior cranial fossa of 15 antiseptic fixed cadaveric heads specimens, 9 successive orbital coronal planes were made.The width?thickness?area and distance of rectus muscles on section 2~5 were observed and measured. Results: The ratio of the area of rectus muscles to the area of orbit was (20±3)%,(27±2)%,(23±3)%,(13±1)% on section 2~5, respectively. The ratio of the total thickness of the horizontal muscles to the corresponding width of orbit was (36±4)%,(39±5)%,(33±5)%,(24±4)% on section 2~5, respectively. Conclusion: The two ratio both can evaluate the developing likelihood of optic neuropathy in Graves′Ophthalmopathy. Coronal planes of orbit showed the interrelation of the spaces in orbit, which provides morphological data for imageologic diagnosis of diseases inside the muscle cone.
