The Utility of Three-dimensional CT in Orbital Diseases

ABSTRACT

PURPOSE: Orbital computed tomography was useful for evaluation of orbital truama because it can visualize most soft tissues, foreign bodies and bone details. Advancements in computer software makes three diemensional CT available with more higher quality and reasonable cost. We studied the officency, merit and limitation of orbital three dimensional CT. METHODS: We evaluated the conventional orbital CT and three dimensional orbital CT of the patients visited department of ophthalmology and emergency room to orbital trauma or other orbital diseases. RESULTS: The three dimensional orbital CT was not superior to conventional orbital CT in evaluation of orbital soft tissue disease but useful for evaluation of orbital bony details. CONCLUSION: In cases of coexamination with conventional orbital CT, the three dimensional orbital CT was useful for diagnosis and surgical planning in orbital truamatized patient.
