【 摘 要 】

Zygomatic fractures are among the most common fractures to the facial skeleton. However, because no standard and reliable method of evaluation is available to assess postoperative patients, we often rely on photographs and subjective assessments. A portable mirror stand device (MiRS), which is a new method for the standardization of photography, was developed in our institution. Used with image analysis software, this device provides a new method for evaluating outcomes after the open reduction and internal fixation of zygomatic fractures. The portable mirror stand device was set up in our outpatient clinic at the Cleft Craniofacial Center at Cipto Mangunkusumo Hospital. Photographs of 11 postoperative patients were taken using the device, and they were analyzed both manually and using image analysis software (ImageJ 1.46) for symmetry. The two methods were then compared to assess the correlation and agreement of the results. The measurements taken using the manual method and the software-assisted method did not differ significantly, which indicated the good agreement between the two methods. The results of the symmetry achieved atour center were similar to other centers in the Asian region (ΔZy= 3.4±1.5 mm, ΔBc= 2.6±1.6 mm, ΔCh= 2.3±2.4 mm) compared with (ΔZy= 3.2±1.7 mm, ΔBc= 2.6±1.6 mm, ΔCh= 2.3±2.5 mm). The treatment of zygomatic fracture a tour center achieved good results. The portable mirror stand device assisted the image analysis software (ImageJ 1.46), which could be beneficial in assessing symmetry in postoperative zygomatic fracture patients.
