Virtual Surgical Planning: A Game-Changer for Jaw Reconstruction or a Threat to Patient Access?
The world of reconstructive surgery is undergoing a quiet revolution, and it's all thanks to virtual surgical planning (VSP). This innovative technology has the potential to transform the way we approach complex procedures, particularly in the realm of jaw reconstruction. But is it a game-changer or a threat to patient access?
The Promise of VSP
For those unfamiliar, VSP utilizes high-resolution CT imaging and 3D printing to create patient-specific cutting guides, positioning jigs, and pre-bent fixation plates. This allows surgeons to plan the procedure in advance, ensuring a more precise and predictable outcome. In the case of jaw reconstruction, VSP can help turn a straight, linear bone into the curvature of the native mandible, maintain vascularity, and restore occlusion, all in a single operation.
The evidence supporting VSP is compelling. Systematic reviews and meta-analyses have linked VSP to reduced operative duration, ischaemia time, postoperative complications, and length of stay. For surgeons earlier in their careers or units with lower case volumes, VSP provides a safety net, reducing the reliance on individual surgeon experience.
The Catch-22
However, there's a catch-22. Most of the studies supporting VSP are small, and most come from overseas health systems with cost structures very different from ours. There's also a lag between image acquisition, virtual planning, and eventual implant placement, which can vary from days to weeks. This raises concerns about the disparity between VSP's intended and actual use, and its potential impact on patient access.
The Real Risk
The real risk to Australian patients, in my opinion, is the potential restriction of access to VSP. A Commonwealth review has raised concerns about the disparity between VSP's intended and actual use, and its potential impact on patient access. If we lose publicly funded VSP because we haven't done the work to justify it, patients undergoing complex reconstructive surgery will bear the cost, both literally and figuratively.
The Way Forward
What we need now is a coordinated, prospective, Australian effort to capture operative duration, complication rates, length of stay, and true whole-of-episode cost for VSP-assisted reconstruction, benchmarked directly against conventional freehand surgery in our own hospitals. Professional bodies and jurisdictional health departments should fund this as a priority, rather than leaving it to individual units to squeeze in alongside their clinical workload.
We should also be backing the small number of Australian centres building in-house CAD/CAM capability, which sidesteps some of the cost, turnaround, and clinician-disenfranchisement problems that come with outsourcing planning overseas. VSP hasn't solved every problem in head and neck reconstruction, and it isn't free. But it has made a genuinely difficult operation more precise, more collaborative, and more reproducible for the surgeons doing it and the patients relying on it.
The Takeaway
Before we restrict access to VSP, we owe those patients the Australian data that tells us what it's actually worth. It's time to embrace the promise of VSP and ensure that all patients, regardless of their location or background, have access to this life-changing technology.
