Conclusion Measurements of diameter of ovalforamen and flow across it in fetal echocardiography could be an additional diagnostic standard for atrial septal defect.
X-ray 3D-CT and navigation ovalforamen locations were used in 42 cases intractable location so that the direction and position could be defined for trigeminal neuralgia.
The results show that 93% of the suborbital foramen is an oval-shaped mono-foramen and 7% has a paraforamen, their exact positions on the maxilla being measured.
