Treatment of patients with posttraummatic deformations of the zygomatico-orbital complex with the intraoperative navigation system use

Background. Currently, the number of patients with maxillofacial region injuries in relation to the total number of traumas ranges from 3.2 to 15%. Among the maxillofacial area damages, 1230% of them are the middle face injuries. In order to optimize reconstructive interventions, intraoperative navigation systems are increasingly being used.

Aim. To evaluate the effectiveness of navigation systems use during the zygomatico-orbital complex deformations elimination.

Material and methods. Nine patients with different types of posttraumatic deformities of the zygomatico-orbital complex who underwent surgery were included into the study. For preoperative virtual modeling and intraoperative control, the authors used the optical navigation system “BrainLab 18070 Kick”. Clinical examination, X-ray and cephalometric analysis of treatment results showed high opportunities of this method for virtual planning of surgery in combination with intraoperative computer navigation.

Conclusions. Based on the results of cephalometric and radiologic examinations, the authors concluded that the use of virtual planning and intraoperative computer navigation in the posttraumatic deformations elimination makes it possible to increase the accuracy of surgical intervention, and the error in the positioning of bone fragments and reconstructive implants is no more than 0.3 mm.
