Superior orbital fissure syndrome. Secondary to infected dentigerous cyst of the maxillary sinus.

: Superior orbital fissure syndrome is a rare condition that presents itself as gross and persistent edema of the periorbital tissues, proptosis, subconjunctival ecchymosis, ptosis, ophthalmoplegia, dilation of the pupil, absence of direct light reflex and presence of consensual light reflex. The corneal reflex is lost, sensation is diminished over the forehead, and it is possible that the dimensions of the superior orbital fissure are reduced. Infection, however, is not often reported as the etiology. The case presented here describes an unusual occurrence of superior orbital fissure syndrome secondary to an infected dentigerous cyst of the maxillary sinus and its management.
