Facial fillers are an increasingly more common cosmetic intervention throughout the United States, and the world, in general. We have learned much about filler materials, injection techniques, and how to prevent complications. What is still “hotly” debated is how to best deliver the filler material – a cannula vs needle?
Here are some points to consider for the patient when the filler treatment is performed.
- Fillers were initially given only with needles. The cannula – a blunt tipped delivery device – was introduced in the last 5 years to give an option other than using a sharp needle, which can cause more bruising than a blunt device and can more easily potentially enter a blood vessel which can lead to severe complications.
- There is a learning curve to using the cannula, so make sure your injector is well-experienced in using one.
- All well-trained and experienced injectors should be comfortable with both the cannula and the needle.
- Experience has shown that both techniques are effective and there are no evidence-based studies showing superiority of one over the other. However, a recent cadaver study has shown the cannula delivery is more precise in where the filler is placed.
- When the cannula is used one entry site is usually sufficient to deliver the filler to many locations. With the needle, this is less so, and more entry sticks are needed, which is more traumatic
While the needle and cannula can both be used to deliver filler, patients should know the differences so they can be involved in their treatment plan.
