[Differential diagnosis of superior orbital fissure syndrome].

Paresis of cranial nerves III, IV, VI and the ophthalmic nerve is termed fissura-orbitalis-superior syndrome. It is caused by affections of the surrounding bones, vascular lesions in the region of the cavernous sinus, tumours of sella and sphenoid bones and diseases of the orbital cavity. Cranial computed tomography (with and without contrast enhancement) is a reliable diagnostic method which may be supported by angiography of NMR in individual cases.
