HE AGEING OF THE HANDS IS A common complaint of many patients. A very simple, safe and effective solution for augmentation of the ageing hand is available through the injection of a soft tissue filler, such as Varioderm®, a highly


cross-linked hyaluronic acid filler. Varioderm® was injected by the author using a tunnelling technique with a blunt 18 gauge cannula. Adverse events did not occur, and patients were very satisfied with the result. This article explains in detail all the aspects with regard to the injection technique.


Background With ageing, cutaneous atrophy and a loss of subcutaneous fat, with a prominence of underlying veins and tendons, can occur in the hands. Although the more superficial changes can been addressed using a range of methods, the deeper changes — namely the loss of volume — have usually been ignored. In order to correct lipoatrophy of the dorsum of the hands, and to improve total skin appearance, a number of injectable fillers can be used.


Since the use of hyaluronic acid fillers in aesthetic medicine was first introduced, the problem with resorbable fillers has been the inverse relationship between safety and the lasting effects once injected. A new kind of hyaluronic acid filler, Varioderm® (Adoderm, Langenfeld, Germany), uses an innovative technology — Monophasic Particle Technology (MPT®) — to increase the duration of the filler in soft tissue, with no detrimental effect on safety. Therefore, using a technique free of the difficulties of autologous fat transfer, it is possible to achieve a long-lasting filling effect of the ‘canals’ that show on the dorsum of the hand, with the added bonus of simplicity and safety of the technique applied.

■Insulin syringes ■Sterile 20 G needle ■Sterile blunt cannula (70 mm), 18 G disposable or reusable


■Sterile gauze, iodinated antiseptic solution ■Retrograde injections, subdermal level.


Injection technique Place the patient’s hands on a procedure table, palms down, with an sterile cloth beneath, then proceed to undertake correct antisepsis using the iodinated solution. On the skin crease that forms on the wrist with the


hyperextension of the hand, the author injects 2 cc of local anaesthetic per hand. The papule that forms is gently spread in a radiating fashion to fully disseminate the anaesthetic agent. Then, using a 20 gauge sterile needle, the author makes a small hole in the skin of the area previously anaesthetised (Figure 1). A blunt, sterile cannula, disposable or reusable


(according to the preference of the injector), is then inserted through the perforation previously made in the skin (Figure 2) and advanced in a distal direction along the canals, surrounded on both sides by the tendons (Figure 3). Once in the most distal position, retrograde injection of the filler is commenced (Figure 4). A slight grey hue is visible owing to the Tyndall effect. Some gentle massage along the line of the injections will help to distribute the Varioderm® Plus product more evenly. There is no need to completely extract the needle to re-start injecting in the neighbouring canal. The laxity of the tissues in the zone makes a rotation of the cannula to re-position it very easy to perform. It is possible to immediately compare results of the hand already treated with the untreated hand (Figure 5).
