Abstract
Orbital floor fracture is one of the most common maxillofacial fractures. Hence, many clinical methods were implemented for improvement of the techniques used.
Objectives: To evaluate the clinical performance of customized PEEK implant in the treatment of patients with orbital floor fracture.
Materials and methods: 9 patients with recent orbital floor fracture were selected. All patients were treated using customized PEEK implants in orbital floor reconstruction. Patients were evaluated after 24-hours, one, four and six weeks for enophthalmos, diplopia, ocular motility and infraorbital nerve function in comparison with preoperative status. In addition, a radiographic investigation was performed immediately to confirm the proper placement of the implant and complete release of orbital soft tissue from the maxillary sinus. Another CT scan was performed after 3 months postoperatively to ensure adequate regain of the preoperative value of the orbital volume.
Results: the study was conducted on seven patients with ZMC fracture and 2 patients with blow-out fracture. None of the enrolled patients showed postoperative diplopia. Six out of the enrolled nine patients in this study reported a subjective abnormal sensation in the course of the affected infraorbital nerve at the first follow-up period. However, all patients regained normal sensation by the end of the follow-up period. The difference of the rate of postoperative ocular complications was statistically significant over the follow-up periods (p=0.036).
Conclusion: The favourable clinical performance of the patient-specific PEEK sheet in the management of orbital floor defects makes it an exemplary reconstructive alternative with superb compatibility, great surgical precision and predictability.
