Dr Chou still does XL implants. Also Dr Pelletiere in Chicago, Dr Hedden in Alabama and Dr Bandy in Orange County. I heard just this last week that Dr Lawton in San Antonio just did 1500cc. So there are other options for overfilled saline.
I've not seen any results from Dr. Chou's XL work at this point. I have heard of Dr Lawton in the past, and he's much closer to us, but again, I haven't seen any real-world results of true XL with him. Pictures on his website seem to suggest 800-1000 maximum, so I question how many XL surgeries he has done.
We've seen the results of surgeons who try to go too far out of their expertise range, and aren't aware of the complications that arise with larger sizes. These surgeons tend to be anxious about putting patients outside the norm on their websites.
My wife chose Dr. Pousti years ago primarily due to the ready availability of examples of his work, after a bad experience with a "recommended XL implant surgeon".
When she goes to upsize eventually, we don't want to rush into a procedure with someone unproven - since her complications were minimal with Dr. Pousti.
