Abstract

|
|
Background:Among facial fractures, nasal bone fracture, zygomatic arch fracture and mandibular subcondyle fracture take a large portion. Among surgical operations for nasal bone fracture, zygomatic arch fracture and mandibular subcondyle fracture, closed reduction has been generally used but, unlike open reduction, there is a problem in evaluating its accuracy of reduction.
Methods:An assessment was made from October 2011 until April 2013 prospectively on 37 patients. For all the operations, closed reductions were executed in a conventional way and simultaneously using C-Arm to verify the reduction of fractures. Two images of plain radiography, one taken before operation and another one taken one day after the operation, were compared. After obtaining images of plain radiography using C-Arm immediately after the correction upon operation, they were compared with the images of plain radiography taken one day after the operation.
Results:The fracture reductions of 26 patients among 27 nasal fracture patients were satisfactory but one patient showed a marginal overcorrection of less than 1 mm. The fracture reductions of 7 patients among 8 zygomatic arch fracture patients were satisfactory but one patient showed a marginal undercorrection of less than 2 mm. All of two mandibular subcondyle fracture patients showed less than 2 mm undercorrection.
Conclusion:Closed reduction guided by C-Arm for nasal bone fracture, zygomatic arch fracture and mandibular subcondyle fracture was clinically useful because it could make a real-time assessment on fractured areas and add immediate corrections during the operation.
