Optimal diagnostic tool of facial bone fractures is computed tomography(CT). When we diagnosed the facial bone fracture, we routinely used axial & coronal view of CT. But, development of software related CT enabled the application of various views recently. The purpose of this study is to evaluate about usefulness of sagittal view of the CT. Group I was the axial & coronal views about 15 patients with orbital floor fracture. Group II was the axial, coronal & sagittal views about same 15 patients. We asked 4 senior residents of department of plastic reconstructive surgery & ophthalmology, Yeungnam university hospital question about their confidence and usefulness. Compared with group II to group I, group II was more useful result. Using Pearson's chi-square test, statistical significance was checked (p<.05) about almost questions. It means that sagittal view is useful tool for orbital floor fracture.

Purpose: Aging society was realized after persons over 65 was rated above 7% in 2000. It is inevitable fact that society gets older. Few study about facial bone fracture in elderly was reported until now. This study provides a retrospective statistical analysis of facial bone fracture and reports of some demographical information from medical records. Methods: From January 2000 to December 2005, 123 cases of facial bone fracture in above 55 year-old persons were reviewed and analysed. Statistic data was related to distribution, age, sex, causes, occupations, occurrence, time, incidence of facial bone fracture, treatment and it's complications. Results: Facial bone fractures in elderly tend to increase and rated to 4.7%. Facial bone fractures in elderly were most frequently occurred in farmers, cultivator accidents and zygoma fractures. A few minor complications were checked, but easily improved.Conclusion: Facial bone fractures in elderly have small proportion of the whole facial bone fractures, but gradually have been increased. This study was observed trends in changes of facial bone fracture in elderly for 5 years and expected to provide statistical index to prevent facial bone fracture in elderly.

For over two thousand years, many artists and scientists have tried to understand or quantify the form of the perfect, ideal, or the most beautiful face both in art and in vivo(life). However, this mathematical relationship has been consistently and repeatedly reported to be present in beautiful things. This particular relationship is referred to as the golden ratio. It is a mathematical ratio of 1.618 : 1 that seems to appear recurrently in beautiful things in nature as well as in other things that are seen as beautiful. Dr. Marquardt made the facial golden mask that contains and includes all of the 1-dimensional and 2-dimensional geometric golden element formed from the golden ratio. The purpose of this study is to evaluate the usefulness of the golden facial mask. In our cases(n=40), the authors applied the facial golden mask to the preoperative and postoperative photographs, and scored each photograph. Compared with the average scores of the facial mask applied photographs and none applied photographs using non-parametric test, statistical significance was not checked (p>0.05). It means that the facial golden mask can be used for facial analysis. The facial golden mask is easy to apply, cheap and relatively objective. So, the authors introduce the one of useful facial analyses.
