In today’s article, we will help to educate you on the differences between Cannula and Needle in a Dermal Filler Procedure.
Dermal Filler is a minimally invasive procedure that requires a great amount of observation and precision as it is being administered on the face where many vessels are located. This has made Aesthetic Cannulas a popular “safety tool” among practitioners due to its long and blunt tip, especially when it comes to largerto dangerous areas of the face. Many Dermal Filler products are now equipped with both Needles and Cannula for practitioners for their tool of choice in injections but how does one decide between these two options? Let’s explore the advantages and disadvantages of needles and cannulas for us to identify which tool works best.
Needles in Dermal Filler
Needles in Dermal Filler is definitely great when it comes to precision and is easier to use since practitioners are trained mostly with it. However, the sharp tip of the needle could puncture the facial vessels and cause unwanted complications if you do not have the knowledge on facial anatomy and the right estimation of injection. It is normal to get bruises with needles or cannulas but needles have a higher chance in creating facial traumas or vascular events if you are not properly trained.
With its short tip, practitioners would need to puncture more skin to create the volume that they desire. Popularly, needles are mostly used to place supraperiosteal and lip injections, and are great for low volume & low pressure injections.
Cannulas in Dermal Filler
Practitioners that are using Cannulas for Dermal Filler are on the rise as patients are satisfied with the minimal amount of bruising and inadvertent injections into vessels that is commonly known for needles. It also has a lower risk of infection from the amount of injections needed. To note, this blunt tool requires an initial puncturing needle to create an access point for the cannula to enter and direct itself to the area where it needs filling.
Sadly, the use of Cannula is limited to wider part of the facial area. When it comes to small amount of filling or touch ups, the precision of a needle is required for areas such as the cupid’s bow, upper lip and temples. Cannulas may not be an ideal tool for superficial surface to inject acne scars and super fine lines. Ultimately, it all comes down to the knowledge and skill of the injector to be able to administrate the treatment to receive the optimal placement and results that you want.
How do you select a cannula for fillers?
As you know, different parts of the face has different texture and consistency. Therefore, the prudent practitioner must be able to select the correct length, diameter and flexibility. For example, a 25 G, 40 mm, rigid needle is more suitable than a 27 G, 40 mm, flexible needle for nose augmentation. On the other hand, using a cannula is not necessarily always safe. There have been incidences where cannula have penetrated blood vessels. At the end of the day, the practitioner’s expertise and skills are important.
