We performed a clinical analysis of 145 children younger than 15 years who had oral and maxillofacial traumatic injuries treated at the Department of Oral and Maxillofacial Surgery, Asahikawa Medical University during the past 5 years (April 2004 to March 2009). The following conclusions were made:
The ratio of male to female patients was 1.8:1. As for the age distribution, 1-year-old children had the highest incidence of injuries. Analysis of the monthly frequency of injuries showed that September was highest month, and February was the lowest month. Forty percent of the patients visited our hospital on a Saturday, Sunday, or national holiday. The highest proportion of injuries occurred between 15:00 and 18:00. About 87% of the patients visited our hospital directly, and 88.2% of the patients visited our hospital on the day of injury. The causes of injury were falls and drops (66.2%), traffic accidents (8.9%), and sports (7.5%). The most common site of soft tissue injury was the lip, and the most common site of tooth injury was the maxillary anterior primary teeth. Half of the patients were observed without any surgical treatment.
