Background: To investigate the ability of routine cranial computerized tomography (CT) to detect facial bone fractures, taking maxillofacial, orbital and temporal bone CT as a reference.
Materials-methods: Patients presenting to the emergency department with head trauma and undergoing cranial CT imaging were included in the study. Cases in the study group were also assessed using at least one of maxillofacial, orbital or temporal CT.
Results: Fracture was present in 155 patients at maxillofacial, orbital or temporal CT. Fifty-nine patients had a single fracture and 96 more than one fracture. Fractures were determined completely and accurately in 71 patients using cranial CT. Cranial CT wassuccessful in thefracturediagnosis of 48 of 96 patientswithmultifractures but all of thefracturelines in thesepatientswere not ableto be shown. Eleven patients were reported as false positive.
Sensitivity of 45.8%, specificity of 93.1%, a positive predictive value (PPV) of 86.6%, a negative predictive value (NPV) of 63.8% and a kappa value of 0.39 were determined for the effectiveness of cranial CT. Eleven out of 21 fractures in the temporal bone, 33 out of 50 in the nasal bone, 27 out of 35 zygomatic fractures, 3 out of 4 occipital fractures, 8 out of 17 patients with ethmoid fracture and 19 out of 23 patients with frontal fracture were identified using cranial CT.
Conclusion: Advantages such as a thin slice thickness, a bone algorithm and reformat images assist the detection of small, non-displaced fractures at temporal, maxillofacial and orbital CT.
