ABSTRACT
This technique was developed 20 years ago. At that time, there were no cross-linked hyaluronic acid products; when they became available, the technique began to be modified and adapted until finally reaching the form described here. It has been performed on more than 23,000 patients, of whom 30% have had one or more surgical rhinoplasties. There have been nine accidental injections of hyaluronic acid intra-arterially that—with the hyaluronidase protocol used in the right time and form—have all resolved without necrosis of dermal tissue.
