Abstract

On the basis of radiological positive findings of 101 cases, facial bone fractures are analysed according tothe location and predilection of fracture site with the transmited other adjoining facial bone fractures by forcebeing observed, as follows ; 1. Among the facial bone fractures, visible on various view, the mandibular fracturesare most common, of which percentage is 53.4% and the other facial bone fractures in order of frequency is asfollows; orbital wall fracture is 32.6%, nasal bone fracture 19.8% and frontozygomatic suture separation 16.8%. 2.Comparing the percentage of visible facial bone fracture on skull AP and lateral view with that of the facial bonefracture taken on various views; the mandibular fracture is found in 52.5% on skull AP and lateral view out of53.4% on various views, ethmoid fracture in 7.9% out of 8.9%, maxillary process fracture of frontal bone in 6.9%out 7.9% and the nasofrontal suture separation in 5.9% out of 6.9%, and the skull AP and lateral view are besthelpful for detection of above fractures. 3. On water's view most of the facial bone fractures are detected,except the fractures of the mandible, ethmoid and nasal bones and the nasofrontal suture separations. One of thetwo cases of the maxillary bone fractures which are not visualized on Water's view is the alveolar portion of themaxillary bone, which is however visualized on the skull lateral view. 4. By the skull AP, lateral and Water'sview, the most of the facial bone fractures are detected except nasal bone fracture due to improper angle ofcentral beam and different densities, however the accurate location and extension can only be visualized on thespecial view such as optic foramen view, TM joint view of the mandible, zygomatic arch view and tomography. 5. Themaxillary bone fractures are frequently associated with the facial bone fractures on the same side, such asinferior wall of orbit in 84.0%, zygomatic arch in 56.0%, malar part of zygoma in 56.0% and frontozygomatic sutureseparation in 48.0%. 6. Among the subsequent case of increased haziness in the maxillary antrum, the incidence offacial bone fractures are markedly increased on the same side and the haziness may be from post traumatic edema,exudate and hemorrhage in the maxillary sinus.
