Clinical and CT Findings of Children''''s Orbital Fractures

The authors analized 40 children of orbital fractures under the age of 14.Causes of fractures were pounding,falling as well as hitting injuries.Clinical findings often included visual loss,diplopia and limited movement of the globe,CT findings usually included interruption of bony continuity of the orbital wall,accounting for 71.4% and displacement of the orbital wall(28.6%).Direct orbital fractures were most often(50.5%). Blow-out fractures(33.3%) and complicated fractures(16.7%).The medial orbital wall was the most fracture favourable location,the inferior,lateral and superior walls occured subsequently less frequent.CT findings also included thickening and enlargement of the extraocular orbital muscles,The authors concluded preliminarily that children's orbital fractures had some features and CT could provide information for early diagnosis and therapy as well as predicting prognosis.The authors also analized difference between children's orbital fracture and adult's orbital fracture.
