This should not be construed as medical advice. I am a retired Board Certified Plastic Surgeon.
I have been dreaming of such reconstructive options for decades. Finally saw something that is the closest yet to my fantasies. 3D printers using living tissues for their inks. 3D printer and living "ink" create cartilage
is a description of making cartilage shaped for implantation. This is a nice ideal framework that hopefully will present with warp less options that plague rib graft methods. My career is over, but the sad part is that this may be more than 20 years away from real use. These are much more viable options than silicone implants, but have much testing before practical. Not even discussed would be more complex blood supply connected framework of cartilage and skin. Now we are talking about the real ear fabrication and possibly an essential step before we obtain an ear that maintains it shape and is as delicate and natural as the normal human ear. 'Printing' human organs with 3D bio-printer
US researchers at Cornell University have engineered an ear made of silicone using a 3D printer, which they hope will one day be capable of producing functional human body parts.
uses silicone for their printing. The problem here is that silicone implants tend to erode through the skin and tend to need thick flap based tissue coverings that hide delicate structures. Like many ear reconstructions, they may be miracles in concept and execution, but until you see what they look like on live patients, do not hold your breath. That is the issue with much ear reconstruction. Try to find examples from that method that look great. If you have such examples, post them here or add links to resources with such work. The proof is in good Standard Ear Picture Documentation
If we are going to fantasize again with no limits, let us have the 3D printers give us a cartilage framework that does not warp integrated with a blood supply one or 2 arteries and veins to hook up to the patient, and even further, a nerve supply that also can be attached, and this covered by a natural thin skin layer that can be matched to the color of the patient. Oh well, back to my working Harry Potter Magic Wand
Hope this helps,
