The positions of 20 trigeminal nerves in the skulls of 12 cadavers were evaluated radiographically. Small metal clips were attached to the nerves and radiographs were obtained in straight AP, Towne and lateral projections. It was found that the trigeminal nerve had a fairly constant position in the skull with respect to the internal auditory meatus in the AP and Towne projections and the petrous ridges in the lateral view. This information can be used during vertebral angiography to predict whether an arterial loop is sufficiently close to the trigeminal nerve root for arterial compression of the nerve, causing trigeminal neuralgia, to be a realistic possibility.
对12具尸体颅骨中20条三叉神经的位置进行了放射学评估。在神经上附着小金属夹，并分别在前后位、汤氏位和侧位投照下获取X光片。结果发现，在前后位和汤氏位投照中，三叉神经相对于内耳道在颅骨中的位置相当恒定，在侧位片中相对于岩嵴的位置也较为恒定。这些信息可在椎动脉血管造影时用于预测动脉袢是否足够靠近三叉神经根，从而有可能导致神经受压引发三叉神经痛。
