Abstract:
Objective To investigate the multi-slice spiral computed tomography (MSCT) features of crush maxillofacial frac-tures in the massive Wenchuan earthquake. Methods MSCT data of 85 patients with crush maxillofacial fractures caused by earth-quake were retrospectively analyzed. The anatomic distribution of fractures was evaluated. Results In 85 patients, single bone frac-tures (59 patients) were more common than multiple bone fractures (26 patients) (P<0.05). The fractures involved isolated mid-face, isolated mandible, and both were found in 49 patients (57.6%), 24(28.2%), and 12(14.2%), respectively. Midface frac-tures were most frequent (P<0.05). The fractures of condyle, posterolateral and anterior wall of maxillary sinus, zygomatic arch and lateral orbital wall accounted for 47.1%(24/51) ,41.5%(22/53) , 37.7%(20/53),71.9% (23/32) and 63.2%(24/38) of the total fractures of the corresponding maxillofacial bones. Conclusion Isolated bone fracture and midface factures are the main fea-tures of crush maxillofacial fractures resulted from the massive earthquake. MSCT and three-dimensional reconstruction images can demonstrate maxillofacial fractures well.
