Abstract

Objective: The objective of this study was to evaluate the accuracy of custom-made fixation plates in the management of
zygomatico-maxillary complex fracture and outline the processing time required for their fabrication.
Materials and methods: The study is a single arm non-comparative clinical trial study was designed to assess the clinical
performance of custom made mini-plates in the management of zygomatico-maxillary complex fractures. The study was
conducted on 12 patients with unilateral displaced zygomatico-maxillary fracture that needed surgical intervention. All of the
enrolled patients were radiographically examined using Multi slice-Computed Tomography (MSCT) Scan for proper diagnosis
and preoperative virtual planning.
Results: Twelve patients were included in this study, Regarding the clinical follow-up parameters, all the patients reported a
statistically significant decrease in the reported postoperative pain across the follow-up evaluation period (p<0.01), regarding
the infra-orbital nerve function and midface cheek sensation, only 3 patients reported an aberrant sensation at the first followup
interval. By the end of the follow up period, all the enlisted patients reported a normal cheek sensation. Regarding the
postoperative ocular complications, only one patient which reported an early ectropion in the lower eyelid. All patients reported
resolution of the edema at the end of the clinical follow up period. In the postoperative Multi Slice-Computed Tomography
(MSCT), accurate bone reduction was observed in all the cases.
Conclusion: The utilization of computer-aided surgery and rapid prototyping technologies in modern times has rendered them
a viable choice with minimal drawbacks for managing zygomaticomaxillary complicated fractures. The patient-specific fixation
implants that were virtually created showed positive processing, clinical, and radiographic performances with a respectable
level of precision.
