-Abstract-
With the increase of industrialization, leisures, sports activities and traffic, the risk of
trauma has increased markedly.
Midfacial bones are relatively common sites of trauma, and are difficult sites of
correct reduction and reconstruction, because midface is composed of mostly thin cortical
bone surrounding cavities filled with either air or fat with discrete areas of bony
condensation.
A clinical study on 208 patients with midfacial bone fracture who visited Sanggye
Paik Hospital during 5 years(1990∼1995) was done by analyzing sex, age, cause,
fracture site, treatment method, complication and involvement of other body part, etc.
The results obtained were as follows :
1. The occurrence was more frequent in male than in female with ratio of 2.7 : 1 and
most frequently in twenties.
2. Traffic accident was the most common cause of midface fractures.
3. Zygoma was the most frequently occurred site(50%) of midface fractures.
4. Simple fracture(75%) was more frequently occurred than compound fracture(25%).
5. As treatment method, open reduction(76.4%) was used more frequently than closed
reduction(23.6%).
6. Generally, operations are done in 5 days after admission(59.1%), and intermaxillary
fixation was done in 78.4% of cases.
7. Teeth and alveolar bone damages were occurred in 32.2% of cases.
8. Other injuries that were related to midface fracture occurred in 63.3% of cases.
9. Post-operative complications occurred in9% of cases.
