INTRODUCTION: The breakings of the orbital wall can be classified in two categories: the ones that attack and the ones that do not attack the orbital kidney. Those that also do not attack the orbital kidney are called interns. They are caused by traumas in the orbital region. The theories that try to explain the mechanism of this breaking are two: the sudden increase of the orbital pressure is transmitted to the wall, that, for being more fragile, is breached; second says respect to the transmission of the force exerted for the trauma through the osseous structures, breaching the wall in the place most fragile. Had to this local fragility must be attempted against for the cares in preventing valsalva manoeuvres, a time that the same one can take air for the orbital cavity. The symptoms that more bother the patient, and that frequently they lead to the diagnosis, are dyplopia, that can be painful, orbit emphysema accented and enophthalmia, whose sprouting can be delayed. CASE REPORT: R.S.J., masculine sex, after suffered trauma from face during a car accident, evolving 2 days, with bieyelid edema important and reduction of the ocular movement after reflected sternutatory. It was requested a computerized tomography of the face that evidenced breaking of the papyraceous blade and pneumo-orbit. It was dealt clinically with corticotherapy and evolved with complete remission of the symptoms in 3 days. CONCLUSION: The pneumo-orbit is a rare injury of paranasal sinus, that can expand the orbit and to result in proptosis or reduction of the ocular movement. However with diagnostic precocious and adequate treatment the orbit symptoms will be decided.
