This is a practical & retrospective study about patterns of oral & maxillofacial injuries on mine accident. The authors examined injury causes at a coal mine & reviewed the literatures of injury mechanisms. The study was based on a series 90 patients with oral & maxillofacial injuries in mines which had been treated in wonju christian Hospital from Jan 1982 to Dec 1986.
The results obtained were as follows;
1. The most common cause of mine accident was falling down of variable minerals (24%). And explosive injury (23%) & mine-car accident (17%) were next in order of frequency.
2. The multiple lacerations was the most common type in falling down injury and tatoo, foreign bo dy impaction & avulsion were the most frequent injury in explosive accident.
3. Zygoma fracture was the most frequent in mine-car accident & maxilla fracture was the most common type in falling down injury. The simple fracture of mandible was more frequent in mine-car accident, but compound fracture in falling down injury.
4. The head & neck injury was the most frequent among the other combined injury with oral & maxillofacial injury and the most common cause was explosive injury.
5. The seven patients (8%) had the chronic occupational diseases, such as, pneumoconiosis & its pulmonary tuberculosis that influenced the poor wound healing.
6. The 62 patients (69%) arrived within 24 hours at Wonju Christian Hospital on accident. And the others (31%) were treated primarily at the local medical clinics and varous complications, such as, infection & malocclusion were occurred.
