@pieper,

I currently support the CMF team at Orlando Health (Orlando, FL). We are hoping to bring planning and 3D printing in-house, which we are already in the process of doing.

CMF surgeons wanted to explore planning and printing solutions for Craniosynostosis cases. Specifically two procedures so far: **Cranial Vault Remodeling (CVR)** and **Fronto-Orbital Advancement (FOA)**. There are more, but these are the ones I have worked on.

> Hi @Fluvio_Lobo can you give a little background on your goals?

My **main** goal is to establish a workflow for planning and 3D printing of anatomical replicas resulting from said planning. For instance, a printed model of the **Orbital Bandeau** that was modeled through the planning.

Here is a picture of what that looks like;

A **secondary goal** is to **estimate** the post surgical appearance of the patient’s skin after the advancement. This is the reason why I am playing around with warping transforms and will soon have to use FEA. I still want to explore a non-realistic warping method as “guesstimation” 🤣

I am working on a few tricks based on your feedback and other feedback I got [here](https://discourse.slicer.org/t/using-displacement-map-to-deform-or-morph-a-segment-model/18552). I have not had a chance to test/update this post, but will do before then end of the week

> Will you be doing this frequently?

Depends on your definition of frequently.

The latest estimate is 8-12 craniosynostosis cases per year (2-3 for **FOA** ). The CMF crew has another **FOA** and two **CVRs** this summer. I think 8-12 and 2-3 are underestimates.

These procedures do not have the volume of say Orthognathic surgery and this is the reason why it is so underserved by commercial applications.
