Abstract
ABSTRACTBackground: Diagnostic imaging has been of recent and unique importance in substantiating the clinicallysuspected existence of the midface fracture and it is essential to be aware of the various procedures available tohelp initially in establishing an accurate diagnosis. The aim of the study is to evaluate the diagnostic accuracy ofpanoramic maxillary sinus projection according to computed tomographical findings in patients with midfacefractures to be used as an emergency radiographic diagnostic aid.Subjects, material and methods: Thirty patients with a midfacial trauma and twenty patients suspected to havingmidfacial fractures. All subjects were examined radiographically using panoramic maxillary sinus imaging system toevaluate the nasal, orbital, maxillary, and zygomatic bone and recorded as either “positive” or “negative”according to the positive computed tomographical midfacial fracture findings.Results: Panoramic maxillary sinus projection was 83.3% sensitive in detecting midfacial fractures line with 90%accuracy and it can establish the diagnosis of any midfacial bones fracture with 100% confidence in any clinicalsetting.Conclusion: If panoramic maxillary sinus imaging is performed as the first imaging modality in case of suspectedmidfacial fractures by an experienced investigator, the visualization of fracture line can avoid conventional imaging,so that only an indicated computed tomography scan can be added.Key words: midfacial fracture, dental panoramic, computed tomography.
