title: Prediction of enophthalmos by computer-based volume measurement of orbital fractures in a Korean population.
abstract: OBJECTIVE
  To estimate posttraumatic enophthalmos using computer-based volume measurement of the orbital fracture to provide information on surgical guidelines.
  
  
  METHODS
  The fracture volume of orbital wall fractures in 35 patients who did not undergo surgery was measured using a Rapidia work station system. Hertel ophthalmometry, diplopia, and ocular motility were investigated. The fracture volume measurements relative to the intact contralateral orbit were correlated with enophthalmos, diplopia, and ocular motility. Patients were examined at the initial visit, then at 1 week, 1 month, and 3 months.
  
  
  RESULTS
  There was a correlation between the fracture volume and enophthalmos. Late enophthalmos increased in size in proportion to the volume of the fractured site. The predicted orbital fracture volume with an enophthalmos measurement of 2 mm or more was 2.30 ml.
  
  
  CONCLUSIONS
  Computer-based measurements of orbital fracture volume can be used to predict overall enophthalmos and provide useful information to surgeons.
