Improved Outcomes of Orbital Reconstruction With Intraoperative Imaging and Rapid Prototyping

Customized Titanium Reconstruction of Orbital Fractures Using a Mirroring Technique for Virtual Reconstruction and 3D Model Printing

“…Thus, by customizing titanium orbital implants on a 3Dprinted biomodel, the surgical precision was increased and the intention to revise followwas decreased. A recent study analyzed the effects of intraoperative CT and rapid prototyping on orbital fracture surgery and found an intraoperative revision rate of 22.7% and postoperative revision rate of 3.3% [32]. These values correspond well with the intention to revise of the 2 experienced consultants in our study.…”

Surgical instrument to improve implant positioning in orbital reconstruction: a feasibility study

“…Intraoperative navigation is a proven technique in orbital reconstruction that increases the accuracy of implant positioning, 8,9,17,22 but its availability is limited. 11,23 Intraoperative imaging can be used to assess positioning, but it does not provide feedback during manipulation of the implant.…”

“…An implant with an anatomical shape in an aberrant position may induce volume discrepancies and/or adverse clinical outcomes, especially if the medial wall is involved, [8][9][10][11] but keyhole access and limited overview due to protruding orbital tissues hamper visual appraisal of its position. 9,[12][13][14][15] Intraoperative navigation, which enables evaluation of the acquired position of an implant during surgery by comparing it to the planned position in the surgical plan, has been shown to increase the predictability of positioning. 13,16,17 Intraoperative navigation is associated with relatively high costs and limited availability, and is restricted to wellequipped centres in developed countries.…”

A Literature Review of Rapid Prototyping and Patient Specific Implants for the Treatment of Orbital Fractures

“…Recently, the introduction of technologies such as rapid prototyping (RP) and intraoperative imaging have been employed to accurately reconstruct the traumatized orbit. [1][2][3][4][5][6][7] RP in orbital trauma involves pre-operative manufacture of a three dimensional (3D) physical model of the patients affected orbit based on computed tomography (CT) data. This is used for operative planning and serves as a template for adaptation of a preformed titanium plate, creating a patient specific implant (PSI).…”

“…Several papers demonstrate that combining RP and intraoperative imaging technologies significantly improves post-operative outcomes. 2,3 This paper is a review of the current literature. The workflow utilized at the authors unit is also presented.…”
