Evaluation of Computer-Assisted Shape-Adapted Fabricated Ti-Mesh Applied to Mirroring-Reconstruct Orbital Walls in Correction of Late Post-Traumatic Enophthalmos

Abstract

restrained, 8 (5%) were restrained with air bag and belt, and 9 (6%) were restrained with air bag only. Of the patients sustaining a fracture requiring surgical intervention, there were 64 (41%) patients with mandible fractures, 52 (33%) with nasal fractures, 59 (38%) with orbital fractures, 50 (32%) with ZMC fractures, 10 (6%) with frontal sinus fractures, 12 (8%) with NOE fractures, 26 (17%) with Le Fort I fractures, 2 (1%) with Le Fort II fractures, and 3 (2%) with Le Fort III fractures. Upon evaluation of seat position, there were no significant differences in total number or severity of maxillofacial fractures between drivers and passengers (p 0.08 and p 0.17 respectively). There were significantly more facial fractures in the unrestrained group versus all other restraint device groups (p 0.001). Of the overall patients requiring surgical intervention to repair their facial fractures, 92 (3%) of the 2796 had no restraint; 47 (1.6%) out of 2969 had 3 point restraints; 8 (1.1%) out of 698 had air bag and belt; and 9 (1.8%) out of 497 had air bag only. Therefore the lack of restraint device patients suffering a motor vehicle collision will double the incidence of facial fractures requiring surgery (3%) versus any other restraint device (1.5%) (p 0.001). Conclusion: At our institution, 3% of unrestrained patients in motor vehicle collisions suffer maxillofacial fractures severe enough to require surgical intervention while only 1.5% of restrained patients require surgery. Therefore, the use of any restraint system results in a significant decrease in the total number and severity of maxillofacial fractures.
