The aim: to evaluate the results of surgical treatment of patients with fractures of the zygomaticorbital complex after reposition and osteosynthesis with fixation at one point along the zygomaticfrontal suture.

The object of the study was 12 patients (10 men, 2 women) with fractures of the zygomaticorbital complex undergoing treatment in the Department of Maxillofacial Surgery No. 11 of the City Clinical Hospital in Minsk for the period from December 2018 to June 2019.

Materials and methods: The patients underwent surgical treatment – reposition and osteosynthesis of the zygomatic-orbital complex with fixation of the fracture along the zygomaticfrontal suture. Surgical access to the fixation point was through the upper eyelid. The results of surgical treatment were evaluated based on a comparative analysis of the clinical picture of patients before surgery and 1 month after surgical treatment. The following clinical symptoms were analyzed: pain in the fracture area; the level of sensitivity loss in the innervation zone of the infraorbital nerve; the presence of bone steps in the area of fractures; deformation of the middle zone of the face; degree of restriction of mouth opening. Manifestations of clinical symptoms were recorded according to our proposed scale from 0 to 2, depending on their severity.

The standing of the fragments after the operation was evaluated by con-beam computed tomography scan. The Wilcoxon test was used to determine the statistical significance of the study results.

Results: 1 patient did not appear for examination one month after surgical treatment (8.3% of the entire sample). Pain in the fracture area, limitation of mouth opening and deformation of the middle zone of the face were absent in all patients who came for examination 1 month after surgery (91.7% of all operated patients). In 6 patients (50.0%) there was a moderate decrease in sensitivity in the innervation zone of the infraorbital nerve, positive dynamics compared with the state before surgical treatment. 5 patients (41.7%) had a complete recovery of sensitivity. 3 patients (25.0%) had a moderate bone step in one of the fracture lines. In 8 (66.7%) patients, bone steps were not determined. When analyzing the studied signs in the group by the Wilcoxon criterion, there were statistically significant differences in the following signs: pain in the fracture area (z = 2.9341; p = 0.0033); the level of sensitivity loss in the innervation zone of the infraorbital nerve (z = 2.9341; p = 0.0033); the presence of bone steps in the area of fractures (z = 2.9341; p = 0.0033); deformation of the middle zone of the face (z = 2.9341; p = 0.0033); degree of restriction of mouth opening (z = 2.5205; p = 0.0117).

Conclusion: Surgical treatment of fractures of the zygomatic-orbital complexes with fixation at one point along the zygomatic-frontal suture showed a positive dynamics in the condition of patients 1 month after surgery. All patients who came to the examination noted the absence or decrease in the degree of manifestation of symptoms present before surgical treatment. This fact indicates the advisability of carrying out the surgical treatment of fractures of the zygomatic-orbital complex with fixation at one point along the zygomatic-frontal suture.
