  • Automated injection system allows physicians to deliver fillers in constant, controlled fashion
  • System may alleviate physicians' muscle fatigue
  • System's price, limited compatibility with some fillers can be an obstacle for some aesthetic physicians

An automated injection system is allowing aesthetic physicians to inject fillers in a constant and controlled fashion, helping doctors achieve better aesthetic outcomes with significantly less pain perceived by the patient. The Injection System by Anteis is set to change the status quo of traditional injection techniques, assuming physicians are open to using the new tool.

The system allows the physician to electronically control and regulate the volume and speed at which a product is injected into the dermis. Not only do patients report less pain during treatment compared to traditional injection techniques, there appear to be fewer and less severe side effects such as bruising, redness and swelling.

Dr. Zenker
"Regardless of how good an injector may be, the material can be introduced into the target area at an even pressure and even amount compared to 'manual' injections, resulting in superior aesthetic outcomes," says Sabine Zenker, M.D., an aesthetic dermatologist in private practice, Munich, Germany. Most physicians agree that the satisfaction of patients receiving hyaluronic acid (HA) filler treatments is a direct result of three things: the efficacy of the injected product in achieving rejuvenation; the severity of side effects as a result of treatment; and the way the product is administered so as to avoid as much pain as possible. Evolving fillers address the issue of efficacy and longevity of effect. According to Dr. Zenker, the Anteis Injection System appears to deliver a given product with less pain and fewer side effects.

The decrease in side effects at the injection site can be appreciated subjectively as well as objectively. In a small series of patients, split-face results comparing the classical injection technique with Anteis' automated injection technique show that the automated injection system results in significantly less edema and bruising (witnessed by less dense tissues) compared to the traditional technique. Results were analyzed using Canfield 3-D imaging technology (Canfield Systems). This objective data indicates that the automated technique is more forgiving to the tissues, resulting in more targeted injection of HA as well as tissue damage and, therefore, less downtime.

PHYSICIAN FATIGUE Physicians who perform many filler treatments can suffer significant muscle fatigue, particularly when performing multiple injection procedures throughout the day. This can take a toll on the physical resilience of the injector, as well as result in less precise filler treatments as the day wears on. Using the automated injection system, the physician has the luxury of concentrating fully on placing the product into the target site without having to worry about manually pressing down on the plunger, sparing the physician physical strain (particularly when injecting fillers of a higher viscosity).

In addition, automated regulation of product flow can minimize the pain perceived on injection, as well as help to avoid "beading" and the uneven placement of filler. The electronically gauged, constant flow of material can be a particular advantage when treating long nasolabial folds or the vermilion border of the lips. Using a long blunt needle, the injector can pass all the way through the nasolabial fold, then slowly retract the needle while leaving small aliquots as the needle is withdrawn.

Dr. Gold
"When using a longer needle, a higher force must be applied to the plunger in order to extrude the filler material. This increased force cannot only result in physician fatigue, but also an uneven injection of material," says Michael H. Gold, M.D., cosmetic and dermatologic surgeon and director of Gold Skin Care Center, Tennessee Clinical Research Center and the Laser and Rejuvenation Center, Nashville, Tenn. "The automated injection system circumvents these variables, and allows you to inject product evenly and in the precise amounts desired to specific targeted tissues."
