Abstract
In 1924, J. G. Raeder1of Oslo reported five cases of paralysis of the oculopupillary sympathetic fibers associated with lesions involving the trigeminal nerve, to which he gave the name paratrigeminal paralysis. To explain this occurrence he gives the anatomic relations as follows: cervical trunk takes origin in the ciliospinal center between the sixth cervical and fourth dorsal segments of the cord. The fibres run from here through the rami communicantes to the upper dorsal ganglion, and through the ansa Vieussenii and the cervical trunk to the upper cervical ganglion. Some of the fibres accompany the external carotid artery to the skin of the face, and oculopupillary fibers reach the base of the brain with the internal carotids, as the plexus caroticus internus. Here some of these fibers run as fine filaments to the gasserian ganglion and join the first branch of the trigeminal nerve; others accompany the
