“…Fractures of the cheekbone and fractures of the middle face are often observed in clinical practice. Typical clinical signs of these fractures are diplopia, flattening of the face, a symptom of "steps" in the area of the infraorbital rim, impaired occlusion and sensitivity due to injury of the hyoid nerve [26].…”

The article publishes the results of treatment of 27 patients with fractures of the face middle area, of which 14 used standard titanium mini-plates to reposition the fragments, and 13 – individual 3D simulated titanium mini-plates / grids. Before and after treatment, its effectiveness was assessed by the values of the displacements of bone fragments and the index of the visual-analog scale, which allows determining the functional and cosmetic effect of the surgery. It was found that the use of individual 3D simulated titanium mini-plates / grids allowed obtaining in 85 % of patients displacements not exceeding 3 mm. In 72 % of patients in whom standard titanium mini-plates were used, the displacement after surgery was 3.1–6 mm, which is significantly greater than in the group with individual modeling of structures. On the 7th day after surgery in the first group (treatment with standard mini-plates), the index on the visual-analog scale was 11 (7; 13), which was significantly (p=0.00147) less than before surgery. In the second group (treatment using individual 3D simulated titanium mini-plates / grids) the index on the visual analog scale was 4 (6; 8) points, which was significantly (Z=3.3; p=0.00098) less than before surgery. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences. The obtained results testify to the greater efficiency of individual 3D modeled titanium mini-plates / grids in comparison with standard titanium mini-plates. The object of the research: fractures of the middle area of the face. Comparison of the visual-analog scale of the first and second groups on the 7th day after surgery revealed the presence of significant (U=2.47; p=0.013) differences. Investigated problem: the comparative evaluation of the effectiveness of the middle area of the face fractures treatment using individual 3D simulated titanium mini-plates / grids and standard titanium mini-plates. The main scientific results: Optimizing the treatment of fractures of the face middle area will help to achieve good cosmetic and functional results. The area of practical use of the research results: Department of Surgical Dentistry and Maxillofacial Surgery. Innovative technological product: The proposed technique using individual 3D-simulated titanium miniplates will help to optimize the treatment of patients with traumatic fractures of the face middle area. Scope of the innovative technological product: Clinical practice.

“…Some people experienced discomfort from the electrical stimulus. Second, the average follow-up period was 4.7 months; this may not have permitted time for neural regeneration, which may take more than 6 months postinjury [20]. However, at the last follow-up examination, most patients had recovered from ION damage.…”

Blink reflex changes and sensory perception in infraorbital nerve-innervated areas following zygomaticomaxillary complex fractures

2020

Background Infraorbital nerve dysfunction is commonly reported after zygomaticomaxillary complex fractures. We evaluated sensory changes in four designated areas (eyelid, nose, zygoma, and lip) innervated by the infraorbital nerve. This evaluation was conducted using the static two-point discrimination test and the vibration threshold test. We assessed the diagnostic significance of the blink reflex in patients with infraorbital nerve dysfunction.Methods This study included 18 patients, all of whom complained of some degree of infraorbital nerve dysfunction preoperatively. A visual analog scale, the infraorbital blink reflex, static two-point discrimination, and the vibration threshold were assessed preoperatively, at 1 month postoperatively (T1), and at a final follow-up that took place at least 4 months postoperatively (T4). The results were analyzed using a multilevel generalized linear mixed model.Results Scores on the visual analog scale significantly improved at T1 and T4. The infraorbital blink reflex significantly improved at T4. Visual analog scale scores improved more rapidly than the infraorbital blink reflex. Two-point discrimination significantly improved in all areas at T4, and the vibration perception threshold significantly improved in the eyelid at T4.Conclusions Recovery of the infraorbital blink reflex reflected the recovery of infraorbital nerve dysfunction. We also determined that the lip tended to recover later than the other areas innervated by the infraorbital nerve.

Introduction: Trauma remains to be a leading cause of maxillofacial injury globally. Motorized two wheelers (MTWs) are the main cause of (73%) maxillofacial injuries in the road traffic accidents; in several studies, the right side of maxillofacial injuries was reported as the common side of injury than left side. In our previous study, the percentage of the right side injuries was higher than the left side.
