N2 - PURPOSE: Three-dimensional imaging using digital volume tomography after reduction of zygomaticomaxillary complex fractures was performed and evaluated.PATIENTS AND METHODS: Ten patients admitted for surgical treatment of zygomaticomaxillary complex fractures were included in the study. All patients were male, aged 17 to 81 years (average, 43.8 years). Preoperative diagnostics and surgical treatment involving open reduction under general anesthesia were performed as usual. One to 3 days (average, 1.6 days) postoperatively, a digital volume tomography data set was generated using the NewTom 9000 (NIM s.r.l., Verona, Italy). After DICOM-import in eFilm Workstation 1.8.3 (Merge Technologies Inc, Milwaukee, WI), axial, coronal, and sagittal reconstructions were evaluated by 6 examiners with the help of 5 defined criteria.RESULTS: One data set was sufficient to visualize all fracture sites of the midface in all patients. Postprocessing using eFilm was successfully performed in all cases. Best scoring results were found regarding bony anchorage of screws and fitting of plates. Remarkable was the low level of metal artifacts in primary and secondary reconstructions, even in close proximity of the material. Most difficulty was encountered during the identification of the medial orbital wall, especially next to poorly ventilated ethmoidal cells. Osseous structures of older patients with decreased bone density proved difficult to visualize.CONCLUSION: Digital volume tomography using the NewTom 9000 is suitable for assessment of postoperative results after zygomaticomaxillary complex reduction.
