Background:  Facial assault trauma has reached epidemic proportions. While the biomechanics of injury, methods of repair, and general demography of blunt facial trauma are well known, statistical associations between epidemiological factors, incidence, and outcome are poorly understood.

Objectives:  To provide a comprehensive epidemiological survey of this patient population. To assess factors determining outcome and pattern of injury.

Design:  Retrospective review of 802 patients admitted with blunt assault facial trauma. Statistical analysis of associations between epidemiological factors, incidence, and outcome with X2 test, 2-tailed t test, and Fisher exact test.

Setting:  Urban university and county hospital.

Results:  Statistically significant associations are demonstrated between gender and the context of assault, incidence of armed assault, presence of fracture, and rate of intoxication at injury. Poor prognostic indicators for outcome include use of tobacco and presence of a mandible fracture. Open reduction and internal fixation were found to bear a higher complication rate only in mandible fractures.

Conclusions:  While choice of treatment carries a statistically significant association with outcome, social variables, including gender, tobacco use, intoxication, and low socioeconomic status, produce dramatic worsening of both injury incidence and outcome.Arch Otolaryngol Head Neck Surg. 1997;123:923-928
