Combined orbito-frontal injuries.

Our experiences in 55 patients suffering from orbitofrontal injuries are discussed. The prognosis is determined by the severity of the brain injuries and the cerebral complications. The relation of fronto-basal, orbital, and maxillofacial fractures to lesions of the brain tissue and contents of the orbita is best demonstrated in high-resolution CT scan. Surgery is usually possible in one interdisciplinary operating session. Penetrating injuries with CSF leakage primarily require operative therapy; indirect, open, frontobasal fractures should be covered secondarily within two weeks following trauma. A debridement of the paranasal sinuses is necessary if drainage is obstructed or infection is imminent. We found no improvement of visual function in eight patients following transethmoidal optic nerve decompression; the visus recovered only in one patient after removal of a bone fragment impressing on the eyeball. Typical complications are systematic or central nervous system infections; less frequent are traumatic cavernous-sinus fistulas and pneumato- or encephaloceles.
