Abstract:
Objective To explore the value of spiral computed tomography(CT)and three-dimensional reconstruction in diagnosing maxillofacial fractures.Methods A total of 86 patients with suspected maxillofacial fractures were enrolled as the research objects.All patients underwent X-ray examination and multi-slice spiral CT combined with three-dimensional reconstruction.Taking surgical results as the golden standard,the diagnostic consistencies of the two methods were recorded,and the diagnostic efficiency for maxillofacial fractures was compared between two methods.Results The surgical results showed that out of 86 patients with suspected maxillofacial fractures,there were 71 confirmed cases(16 cases of zygoma fractures,20 cases of nasal bone fractures,11 cases of mandible and maxilla fractures,12 cases of sphenethmoid fractures and 12 cases of jawbone fractures)and 15 cases of non-maxillofacial fractures.Taking the results of surgical pathology as the golden standard,X-ray showed that there were 56 cases of maxillofacial fractures,11 cases of non-maxillofacial fractures,15 cases of misdiagnosis and 4 cases of missed diagnosis,and its diagnostic accuracy,positive predictive value,negative predictive value and Kappa value were 77.91％(67/86),93.33％(56/60),42.31％(11/26)and 0.405,respectively,having a low diagnostic consistency.Spiral CT combined with three-dimensional reconstruction showed that there were 68 cases of maxillofacial fractures,9 cases of non-maxillofacial fractures,3 cases of misdiagnosis and 6 cases of missed diagnosis,and its diagnostic accuracy rate,positive predictive value,negative predictive value and Kappa value were 89.53％(77/86),91.89％(68/74),75.00％(9/12)and 0.606,respectively,having a high diagnostic consistency.The difference in diagnostic specificity between X-ray and spiral CT combined with three-dimensional reconstruction was trivial(73.33％vs 60.00％,P＞0.05),but the diagnostic sensitivity and accuracy between X-ray and spiral CT combined with three-dimensional reconstruction differed significantly(78.87％vs 95.77％,77.91％vs 89.53％;P＜0.05).Conclusion Spiral CT combined with three-dimensional reconstruction exhibits higher sensitivity and accuracy in the diagnosis of maxillofacial fractures.
