Cannula for dermal filler placement

Traditionally dermal fillers have been administered via a needle and there are still some situations where using a needle is still appropriate. However, with the growing awareness and respect of facial anatomy there has been a move in recent times towards the use of cannulae for dermal filler placement. Blunt tipped cannulas may provide a lower risk of bruising as well as potentially devastating complications for example, vascular occlusion, and skin necrosis. Another reason for choosing a cannula is that they are usually significantly longer than needles and their flexibility and length can be a distinct advantage with less entry points.
