Superior orbital fissure syndrome complicating zygomatic fractures. Pathogenesis and report of a case. Case report.

Superior orbital fissure syndrome complicates zygomatic fractures either when the nerves that cross the fissure are damaged by bone fragments, or when the increased pressure in the orbit at the time of the injury compresses the nerves against the rim of the fissure. Oedema and bleeding may also have the same effect. We present a patient who was treated conservatively, and the ophthalmological problem subsided, although not completely, within a year.
