PURPOSE: The study purpose was to assess the changes in the pattern of maxillofacial @entity174 in 2 different study periods. @entity1 AND METHODS: We conducted retrospective study of 341 @entity1 treated for maxillofacial @entity174 between January 1978 and December 1982 and a prospective study of 483 @entity1 treated between January 1995 and December 1999 at the Department of Oral and Maxillofacial Surgery, University College Hospital, Ibadan, Nigeria. Data were collected on age, gender, etiologic factor, and site of injury. RESULTS: The male-to-female ratio reduced in the second period by a factor of 2.0. @entity1 in the age groups of 21 to 30 years and older than 60 years increased by a factor of 1.8 and 2.9, respectively, in the second period. Assaults, falls, sporting @entity130 , and industrial accidents in the second period increased by a factor of 1.4, 1.5, 3.5, and 1.5, respectively. The ratio between road traffic accidents and other causes changed from 3.4:1 to 2.2:1 in the second period. @entity174 increased by 2% in the second study period. CONCLUSION: The data confirmed that although other etiologic factors are increasing in number, road traffic accidents remains the major etiologic factor of maxillofacial @entity174 in Nigeria. There is a need to enforce seat belt use, speed limit, and drink driving laws to reduce @entity11253 caused by road traffic accidents; to organize preventive programs to minimize assaults, and to legislate the wearing of headgear by industrial workers.
