Accuracy of frozen sections in assessing margins in oral cancer resection.
This study examined the accuracy of frozen section diagnosis of tissue samples from surgical margins compared with the final histologic diagnosis of the same tissue. The total resection specimen was also examined to see whether frozen sections were helpful in predicting negative margins for the entire cancer. The nature of positive and negative margins and their implications for the surgeon are discussed. ⋯ Although frozen sections are extremely accurate, they are not as reliable in eliminating positive margins in the final specimen as the surgeon might hope.

Trends in the incidence and cause of sport-related mandibular fractures: a retrospective analysis.
This study assessed changes in the incidence and causes of mandibular fractures occurring in innsbruck, Austria between 1984 and 1993. ⋯ The results of this study indicate a considerable change in the cause of mandibular fractures, showing that sporting injuries are becoming increasingly common. The high incidence of associated maxillofacial injuries in patients involved in skiing and cycling accidents may suggest an increasing need for preventive and protective measures.
