We usually perform a routine radiographic examination on the maxillofacial trauma patients that visit the emergency room. What is the most effective technique of radiographics in diagnosis of a zygomaticomaxillary complex fracture, or one of the
midfacial bone fracture? What is the most effective technique of radiographics in diagnosis of a mandibular fracture? We performed three radiographic imaging techniques such as Water's, Skull PA, and the Zygomatic arch view to diagnose the
zygomaticomaxillary complex fracture. We performed four radiographic imaging techniques such as Townes', Oblique lateral, Mandibular lateral, Mandibular PA to diagnose the mandibular fracture.
In the 14 patients with a ZMC fracture and 49 patients with a mandibular fracture, useful radiographics were examined by two independent investigators. If the two investigators had different opinions, the final diagnosis was determined by a third
investigator. We used Chi-square analysis with SPSS/PC plus statistic package program.(version 2.0)
1. The accuracy of Water's(71.4%) and the Skull P-A(71.4%)was the highest for the Zygomaticofrontal suture. (Chi-square : 7.0, P<0.05)
2. The accuracy of the Zygomatic arch view(92.9%) was the highest ofr the Zygomaticotemporal suture. (Chi-square : 19.1 P<0.05)
3. The accuracy of Waters(92.9%) was the highest for the Zygomaticomaxillary buttress. (Chi-square 28.5, P<0.05)
4. The accuracy of Watere(100%) was the highest for the Infraorbital rim.(Chi-square, 18.1, P<0.05)
5. The accuracy of Townes'(100%) was the highest for the mandibular condyle (Chi square, 18.7 P<0.05)
6. The accuracy of the Mandibular P-A(88.9%) was the highest for the mandibular angle, but there was no significant difference. (Chi-square 7.2, P>0.05)
7. The accuracy of the mandibular P-A(95.1%) was the highest for the mandibular symphysis. (Chi-square 68.8, P<0.05)
