Abstract

Background: Zygomatic defects that follow trauma may lead to severe esthetic and functional deformities such as ipsilateral facial widening additionally facial flattening. There are many ways to treat the damage either by ready-made or custom-made appliances and implants. Therefore, accurate zygomatic anatomic reconstruction is the key to reestablishing favorable facial normality.
Aim of the study: To evaluate the clinical outcomes of the application of Patient-specific titanium implants fabricated using computer-assisted technique which is a promising method for such midface reconstruction to restore the facial projection, symmetry, and orbital volume.
Patients and Methods: We chose 12 patients who had recent zygomatic bone fractures. They were treated with customised titanium implants. Patients were assessed for ocular motility, diplopia, infraorbital nerve affection, occlusion, and facial symmetry compared to preoperative condition after 24 hours, one week, four weeks, and six weeks. Additionally, a radiographic examination was done right afterwards to check the bone reduction accuracy.
Results: 12 individuals with Zygomatic fractures participated in the study. None of them displayed postoperative diplopia. In this investigation, at the second follow-up, 6 out of 12 patients reported a subjective aberrant sensation along the compromised infraorbital nerve. By the end of the follow-up period, all patients had restored their normal sensation.
Conclusion: In the treatment of zygomatic bone fractures, the customised titanium implants demonstrated promising clinical outcomes, making them an excellent reconstructive option with exceptional compatibility, surgical precision, and predictability.
