Patients and methods
Ten patients admitted to the Department of Oral and Maxillofacial Surgery (Nordwestdeutsche Kieferklinik) of the University Hospital Hamburg-Eppendorf for surgical treatment of ZMC fractures were included in the study. Patients with isolated blowout fractures were not included. 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. Infraorbital and intraoral
Results
One data set was sufficient to visualize all fracture sites of the midface in all patients, but the entire mandible could not be included. Therefore, in 2 patients with additional mandibular fractures a postoperative panoramic view was added. Because of the aperture automatic radiation exposure varied depending especially on the amount of osteosynthetic material present.
Postprocessing using eFilm Workstation 1.8.3 was successfully performed in all cases. Even pseudocoronal and pseudosagittal
Discussion
Computed tomography with primary coronal sections earlier and multislice systems with secondary coronal reconstructions now are the accepted standard for preoperative treatment planning of ZMC fractures. In view of radiation exposure, alternatives like ultrasound or magnetic resonance imaging have been described, but are not standard diagnostic tools, nor have they substituted the CT.17, 18 However, regarding high-contrast structures, DVT offers an alternative to CT imaging resulting in
