Blindness after facial fractures: a 19-year retrospective study
1Department of Oral-Maxillofacial Surgery, Dental School, University of Medical Sciences, Hamedan, Iran. ansari@umsha.ac.ir
Purpose:
We conducted a 19-year review of patients with facial fractures who were treated in the Iranian Maxillofacial Unit at the Mobasher Emergency Hospital, Hamedan Province, Iran, to specifically consider those fractures that resulted in blindness or severe visual impairment.
Materials And Methods:
During the period of February 16, 1984, to March 20, 2003, a total of 2,503 patients with facial fractures were operatively treated. Of these, 550 (22%) patients had orbital region fractures and were specifically studied.
Results:
From our facial fractures database, 83 (3.31%) patients were identified as having ocular or extraocular injuries. Of these, 39 patients (1.56%) had severe visual impairment or blindness.
Conclusions:
Laterally directed forces are implied as major causative factors in blindness or visual impairment. Males (83.3%), left eye (63.3%), third and fourth age decades (53.3%), and motor vehicle accidents (63.3%) were the most commonly involved gender, site, age, and cause of monocular blindness, respectively.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
