Evaluation of the relationship between the pattern of midfacial fractures and amaurosis in patients with facial trauma.

PURPOSE: To evaluate the relation between patterns and numbers of midfacial bone fracture patterns and amaurosis in traumatized patients.

MATERIALS AND METHODS: This is a cross-sectional study of traumatized patients with midfacial fractures who presented to Shahid Rajaee and Chamran hospitals (Shiraz, Iran) from 2010 through 2011. The predictor variable was midfacial fractures and the outcome variable was amaurosis. P < .05 was considered statistically significant.

RESULTS: The study was composed of 112 subjects. Prevalence of amaurosis was 6.25% (7 of 112). Le Fort III fracture was the only fracture pattern that had a significant association with amaurosis (P = .004). Nasoorbitoethmoid fracture was the second most correlative pattern, although this relation was not statistically significant.

CONCLUSIONS: This study showed a meaningful relation between Le Fort III fractures and amaurosis in patients with facial trauma. There was also a high prevalence of nasoorbitoethmoid fracture in blinded patients.
