Efficacy of application of a patient-specific implants in treatment of the orbit walls defects, combined with a cheekbone complex fractures

Abstract

Objective. To study a clinical efficacy of application of a patient-specific implants for elimination of posttraumatic orbital defects, combined with a cheekbone complex fractures, comparing with standard methods of reconstruction.
 Materials and metods. Retrospective analysis of the treatment results was conducted in 43 patients of the main group (n = 25) and in a control one (n = 18), who suffered posttraumatic orbital defects, combined with a cheekbone complex fractures, including the rate of postoperative enophthalm, diplopia and difference of volume between reconstructed and intact orbit.
 Results. Average square of the defects in the patients examined have constituted (6.3 ± 3.5) cm2. The postoperative enophthalm rate in the main group have constituted 18%, in a control one - 44.4%, diplopia rate - accordingly, 16 and 44.4%. Average difference between volume of the intact and traumatized orbit in the main group have constituted (0.94 ± 0.65) cm3 and in a control one - (2.4 ± 2.3) cm3.
 Conclusion. Significant square of the orbit walls damage with extension towards apical parts is characteristic for posttraumatic orbital defects, combined with a cheekbone complex fractures. Reconstruction of orbit and a cheekbone complex, using a patient-specific implants, permits to guarantee an effective rehabilitation of the patients concerning elimination of posttraumatic enophthalm with low risk for the vision acuteness lowering.
