Titanium nickelide in midface fractures treatment

Background: The question of reconstruction of human tissues and organs with the use of medical materials is still open, because of the accurate requirements for their biological and physical features. The aim of this study was to prove the efficiency of titanium nickelide constructors in treatment of isolated orbital floor fractures or combination with zygomatico-orbital complex fractures. Methods: Patients with a fracture of zygomatico-orbital complex and/or low orbital floor (n = 44) carried out different treatments: in the first group, osteosynthesis and endoprosthesis with titanium nickelide structures; in the second group, titan mini-plates osteosynthesis; in the third group ('blow-out'), endoprosthesis with a titanium nickelide mesh; and in the fourth group ('blow-out'), conservative treatment and monitoring (archive data) (p > 0.05). The paraesthesia, diplopia, enophthalmos and exophthalmos degree were measured in points. Results: In one year, the first and second groups had no differences in level of paraesthesia (p > 0.05). The absence of exophthalmos and differences between first and second groups, and between the third and the fourth groups with positive dynamics inside the groups were proved (p < 0.05). In the first and third groups, enophthalmos was absent, and it increased in the second and fourth groups (p < 0.01, p < 0.11). Diplopia in the first and third groups was absent, and it increased in the second and fourth groups (p < 0.05, p < 0.01). Conclusion: The elasticity and biocompatibility of titanium nickelide make the implant insertion and restoration of the lower orbital wall anatomy easier, with good postoperative clinical results. © 2020 by the authors.
