title: Segmental osteotomy in the treatment of obsolete orbitozygomatic fractures.
abstract: Different kinds of orbitozygomatic fractures lead to different levels of orbital structural destructions. Although the magnitude of the management of orbitozygomatic fractures varies considerably, an unsolved and important question remains regarding how to select the best surgical modality according to different kinds of fractures. Among 26 cases of unilateral noncomminuted orbitozygomatic fractures, a segmental osteotomy technique was used to repair the displaced orbitozygomatic complex. The fragment contributing to the orbital structure was mobilized and reduced, whereas the fragment without contribution to the orbital structure was not mobilized and left in situ. Next, the cuneate fragment was imbricated with the orbital osteotomy sites unilaterally or bilaterally. Miniplates and screws were used to span the osteotomy sites and provided fixation once the alignment of the orbit was achieved. The mean difference in volume between fractured orbits preoperatively and postoperatively was 2.47 mL. The mean difference in ocular globe projection was 2.76 mm. When postoperative results were compared with those of the preoperative site, statistically significant difference was noted. At follow-up 1 year postoperatively, the management of orbitozygomatic fractures using segmental osteotomy reduces complications and attains aesthetically satisfying results. Subjective assessment of the patients' globe position found that 88.5% of the patients were satisfied with the outcome, and 11.5% of the patients found it unacceptable. Compared with the traditional method, segmental osteotomy is a simple technique requiring less dissection and can reconstruct the orbital anatomic structure and restore globe position effectively.
