When using a needle, the sharp tip of the needle penetrates through the skin and down to the depth where the filler is injected. In contrast to this, a cannula has a blunt tip, and therefore cannot pierce the skin. A needle is required to make an entry point for the cannula that just passes through the skin. The cannula is then used to pass through the entry point to the areas beneath the skin. The blunt-tipped cannula can re-enter the same entry point again without having to hurt the patient with another needle puncture.
DK Filler Canulla
Because the cannula is blunt, it is not as indiscriminate as a needle as it passes through the tissues. Needles, being sharp-tipped, may more easily pass into or through a vein or artery. This can cause significant bruising or swelling, and at worst, intravascular injection (injection of filler into the artery or vein, which can cause serious complications). Cannulae (plural for cannula), being blunt, are less likely to pass into a vein or artery, and therefore cause less bruising or swelling and tend to avoid intravascular injection.
Instead, the blunt tip tends to push veins or arteries aside as they are passed through the tissues. Furthermore, the practitioner is able to feel resistance from structures that a cannula pass through. Allowing them to judge when and how to apply pressure or manipulate the direction of the cannula. Finally, cannulae tend to be longer than most needles and therefore reach more areas with fewer entry points into the skin.
To summarise, there are many advantages of using a blunt-tipped cannula for the injection of dermal fillers instead of needles. There are advantages for the patient and the practitioner.
