I am frequently asked to comment on Cryoshape Procedure. This is a summary of my opinions and findings concerning this procedure. I have personally observed the procedure and do not endorse it. Below, I outline the reasons for my objections.
CryoShape is an invasive method of freezing keloid tissue, using a long, thick needle, much like a metallic knitting needle. This needle must be inserted into and pass through the keloid and pushed forward to exit from the opposite side of the keloid. The needle is then connected to a source of liquid nitrogen, allowing free flow of liquid nitrogen through the needle. This cools the needle, resulting in the freezing of the keloid tissue. There are, however, several serious issues with this method of freezing keloids.
