[Cavernous sinus syndrome].

Abstract

A clear and concise description and clinical interpretation of the cavernous sinus syndrome are lacking. Pathological changes in or around the cavernous sinus may lead to failure of eye muscle nerves and of one or more branches of the trigeminal nerve. The clinical signs of the cavernous sinus syndrome are combinations of failure of these cranial nerves sometimes with exophthalmus. Because many nerves can be wholly or partially involved in the syndrome, there is no clinical uniformity and the cavernous sinus syndrome has never been well defined. A neurotopographical classification is proposed in order to simplify the multiple interpretations of the cavernous sinus syndrome. The classical cavernous sinus syndrome is divided into three syndromes: the syndrome of the superior orbital fissure, the syndrome of the lateral wall of the cavernous sinus and the central cavernous sinus syndrome.
