Cannula Needles. Are they better to use for lip fillers?

Both cannulas and needles are standard methods for administering filler. However, as you can see, many of us find that using cannulas lessens bruising. I would suggest that you find a surgeon whose work you like and then trust his or her methodology. Best, Dr. Nazarian

I like cannulas to limit complications such as bruising swelling and it makes the treatment more comfortable.  I see less swelling long term.  Best, Dr. Emer.

The jury is really still out on the issue of whether cannulas are really better than needles for injecting fillers and each has its ardent proponents. I have extensive experience with the use of microcannulas, since they were regulatory agency approved and available in my satellite facility in Israel years before they were approved for use in the U.S. (In fact, an Israeli company is one of the major developers and suppliers of microcannulas to the U.S. and elsewhere.) Likewise, I have been using needles for injecting fillers for over three decades going back to the days of their use for injecting the original Zyderm I collagen filler product. I have personally found that needles can just as easily be used in the same fashion as cannulas, i.e. introduced through one or two injection points, rather than via multiple injection sites. In contrast to cannulas, needles do not require the prior use of a larger bore needle to make an initial entry hole through which the cannula may be inserted. Needles precisely because they are sharp-tipped glide through tissue, and do not require the pushing and shoving that cannulas require in order to get through the tissue because they are blunt-tipped. This often makes the treatment time considerably shorter with needles. In general the amount of material needed for injection is typically less with needles than cannulas and placement of the injected materials in many instances can much more precise with needles--something especially important in treating the lips. Finally, since cannula use, despite all the mraketing claims to the contrary, can also result in bruising, I really cannot say that their use overall represents a truly significant advantage over needles.When it comes to lips, using needles, I typically treat through two injection sites per lip, just as one would with cannulas. In the end, what is most important is that you seek consultation by a board certified aesthetic physician with experience and expertise in nonsurgical lip augmentation.
