3D printed surgical models
The technology to print three-dimensional models now exists. Using three-dimensional photographs and software, surgical 3D models can be easily printed. These models provide a much better view and understanding when compared to traditional two-dimensional photographs.
Three dimensional imaging
Three dimensional imaging really has not been of any use in rhinoplasty except for marketing purposes.
What are the pros and cons of using 3d printing for cosmetic surgery?
Other than a toy, it has no place in rhinoplasty. You cannot print living, biocompatible, complex structure like a nose.
3d Printing in rhinoplasty
You can't print a nose, maybe if you needed a prosthesis you could use a 3-d printer, but otherwise I seen no role for 3-d printing for rhinoplasty surgery.
Technology and Rhinoplasty
Innovation is nothing new to the field of Medicine. As rhinoplasty surgeons, we have seen waves of new promising materials, techniques, and implants touting themselves as the easy solution to rhinoplasty. The fact is that rhinoplasty is a highly technical surgical procedure. Surgeons dedicate their entire lives to the "art" of rhinoplasty. That being said, I think technology may provide some additional benefits by decreasing morbidity to patients, such as 3D cartilage printing or 3D implant printing. But nothing will be an easy fix, or deliver perfect results for all patients. Implants in the right patient may be great, but in the wrong patient they may extrude or other unwanted results. Technology is exciting, but be sure to rely on someone who has your best interests in mind and has sufficient rhinoplasty experience.
