According to the this analysis,108 patients were treated conservatively only 12 were under the opereation.Results Interruption of bone continuity, fragments, depression and displacement of orbital bone wall were direct signs of orbital blowout fracture." Tear drop"sign in the maxillary or ethmoid sinus was a characteristic indirect sign of inferior or medial orbital wall fracture. Enophthalmos obviously compacting of extraocular muscler and distraction test male were operation signs.Conclusion Orbital blowout fracture can be diagnosed by SCT volume scanning findings of the MPR comprehensively and accurately, that is very important in choosing the treatment methods for orbital blowout fracture.
