Individualized implants using point-of-care printed models in the treatment of orbital blowout fractures.

ABSTRACT

OBJECTIVE: This case series aims to highlight the digital workflow used by our institution to treat orbital fractures by creating individualized implants using point-of-care, 3-dimensional (3D) printed models. STUDY DESIGN: The study population comprised consecutive patients who presented to John Peter Smith Hospital with isolated orbital floor and/or medial wall fractures from October 2020 to December 2020. Patients treated within 14 days of their initial injury and with 3 months postoperative follow-up were included. Bilateral orbit fractures were excluded because an intact contralateral orbit is needed for 3D modeling. RESULTS: A total of 7 consecutive patients were included. The orbital floor was involved in 6 of the fractures, whereas 1 fracture involved the medial wall. All patients with preoperative diplopia, enophthalmos, or both had resolution by the 3-month postoperative follow-up appointment. Postoperatively, there were no complications in all patients included. CONCLUSIONS: The point-of-care digital workflow presented allows for the efficient production of individualized orbital implants. This method may produce a midface model in hours that can be used to pre-mold an orbital implant to the mirrored, unaffected orbit.
