Serious facial fractures in New Zealand from 1979 to 1998.

We present data on the incidence, aetiology, age, sex and ethnic distribution of facial fractures in New Zealand for the 20-year period from 1979-1998. Most facial fractures (78.9%) occurred in males with a rate of 65.5/100,000, person-years compared with 21% in females with an incidence of 17/100,000. While the injury rate peaked in males between the ages of 20-24 years (200/100,000), it peaked between 15-19 years (34.7/100,000) in females. The most common causes of facial fracture in both genders were assault (14/100,000) and being unintentionally struck by an object or person (9.5/100,000) which is consistent with similar data from South Africa and the USA. The rates of fracture in Maori (68.1/100,000) were approximately twice those of Pacific Islanders (37/100,000) or other ethnic groups (34.2/100,000).
