Twenty years of statistics and observation of facial bone fracture.

We analyse the details of patients with facial bone fractures who visited us from 1993 to 1997, and compare past cases treated from 1978 to 1992. From 1993 to 1997, the total numbers of patients and fractures were 633 and 697, respectively. Thus, we had 127 patients and 139 fractures annually. The number of patients has increased over the years. The highest occurrence rate of facial bone fracture was in the nasal bone (half of all), followed by the malar bone, blowout fractures and the mandibular bone. The rate was the lowest in the maxillary bone. The ratio of males to females was 7:3. Facial bone fractures were most often seen in the 10-29 age group.
