A clinical and statistical analysis on 180 patients with 58 maxillary and 147 malar fractures, treated at the hospital of the Nippon Dental University, School of Dentistry at Niigata, Department of Oral and Maxillofacial Surgery II from July 1974 to December 1992, was retrospectively perfomed. Of fifty five patients, 37 maxillary fractures and 36 malar fractures could not be classified into either Le Fort classification or Night and North type classification assessed by radiographic image. Based on this fact, preliminary type of classification was newly developed for these fractures, i.e., Type I: infra-mid-third facial fracture, Type II: lateral-midthird facial fracture, a; without dislocation or b; with dislocation, Type III: zygomatic bone fracture only. Type IV: supra-mid-third facial fracture. According to our new classification, the most of fractures could be clearly classified. Our new classification also provide in formation on the possible reappearance of clinical symptoms and an appropriate treatment plan. [ABSTRACT FROM AUTHOR] |
