Diagnostic accuracy of physical examination findings for midfacial and mandibular fractures

ObjectivesTo assess the diagnostic accuracy of physical examination findings used to identify patients at risk for midfacial or mandibular fractures.Materials and MethodsA five-year retrospective cohort was constructed from all emergency department with a trauma. The sensitivity, specificity, pre-test probability, positive predictive value, negative likelihood ratio data calculated 19 14 fractures respectively. Computed Tomography panoramic radiography were as index tests.ResultsA total 1484 identified among whom 40.4% 33.4% diagnosed. Overall, specificity found be higher than sensitivity. Regarding fractures, high raccoon eyes, malar eminence flattening that are related palpation, nasal, ocular intra-oral assessment. Malar flattening, external nasal deformity, septum hematoma, change globe position palpable step-off had ad value ratio. mouth opening restriction, auditory canal bleeding, assessment findings, step-off, inferior alveolar nerve paresthesia, angular compression test chin axial pressure test.ConclusionsThe relevant prediction fractures.
