Abstract

The analysis is based on data obtained from 475 cases of oral and maxillofacial injuries treated at our hospital during the 11 years between April 1974 and March 1985.
Maxillofacial fracture is one of the most common cases in oral surgery. Statistically, almost 78 percent involved were males and a steady increase in the number of cases was observed every year.
The majority of patients were between the ages of 10 and 30 yers old, with a peak around 10 to 20 year age group. The etiology of injuries showed individual peculiarity to each age group. Further it was found to have some relation to the injury time.
The majority of patients were consulted within one week of injury. Fracture at mandibular angle and symphysis were the most noticed in this study.
Regarding combination fracture, mandibular with maxillary fracture were quite often observed in this study. Almost 47 percent of patients injured were in main city.
