Recognition of various type of zygomatic fractures and their postreduction stability is essential for correct diagnosis and proper treatment of zygomatic fractures.
We present the classification of the zygomatic fractures of 160 cases. Treated at Han Yang University Hospital for 10 years according to modified Rowe Killey Clasifica-tion; Type 1. Non-displaced fractures 16 cases(10%). Type 2. Zygomatic fractures 60 cases (37. 5%). Type 3. Rotation around vertical axis 8 cases (5%) A. Medial l case (0 6%) B. Lateral 7 cases (4.4%). Type 4. Rotation around 1ongitudinal axis 13 cases (8%) A. Medial O.B. Lateral 13 cases (8%). Type 5. Displacement without rota tion 54 cases (33.8%.) A. Medial 7 cases (4.4%). B. Lateral O.C Posterior, 31 cases (19.4%). D. Inferior 16 cases (10%). Type 6. Rim fractures 6 cases (3.8%). Type 7. Complex fractures 3 cases (1.9%).
The Rowe and Killey classification is superior to the widely accepted Knight and North classification and we think it will more help to predict the postreduction stability and thus help to select the method of treatment according to the type of fracture.
The zygomati fractures with rotation or displacement around a vertical or longitudinal axis. shouId be recognized before the operation and its approachs should be determined depending upon the types of fracture because postreduction stability differs considerably in the various type of zygomatic fractures.
