How does Voluma spread out beneath the skin when using a needle compared to a cannula? (Photo)

I like using cannulas for the majority of my injections as it gives less complications however, there should be no difference in results as the material is placed the same with both needle and cannula.  Best, Dr. Emer.

Both techniques should render similar results if performed with the same intention.  By that I mean, that in general terms, the results should be the same. Needle or Cannula techniques are simply that, a means by which your physician  has chosen to inject the product.  The trials for FDA approval for volume were all needle based. 

Thank you for your question regarding whether there is a difference in the results when using a cannula or a needle. There should be no difference in the results whatsoever. With a  skilled and meticulous Board Certified Facial Plastic Surgeon, there should be hardly any bruising or swelling with the needle technique, provided you have been off your NSAID's and Fish Oils etc for 2 weeks prior. Longevity of the product is not related to needle vs. cannula, rather it depends mainly upon the plane of deposition. (It needs to be placed on the periosteum of the zygoma -cheek bone - to last.) It also depends upon the person, if they engage in a lot of aerobic activity and have a high metabolism, they will go through their filler more quickly than other people.With regards to how many syringes you would need, it is very hard to tell with only seeing a partial view of your face. It looks like  possibly one syringe Voluma  (maybe two) with some feathering of Sculptra inferior to that for a smooth transition to the lower zones. Make sure the Board Certified facial Plastic Surgeon you choose is very experienced and well versed with Facial Contouring techniques and correct location placement of fillers.I hope this helps !Best of Luck in your quest!Dr. Anna Petropoulos, Boston's North Shore

The choice of a cannula versus a needle should not effect the placement of the product significantly.  It would really depend on how much product was used and where it was placed.  I would return to your treating physician for assessment.

The choice for needle vs cannula is one of choice by the physician.  Both deliver the product to the tissues the same way.  The cannula is thought to do less tissue damage.If you feel that you did not get results and that your cheeks have gone back to normal in five days, go and ask your doctor to look at your "before" photos if they were taken.  On numerous occasions, with my own patients, they are shocked to see how subtle but excellent the results are.  You're not supposed to look like you had a major change.  You are supposed to look refreshed, relaxed, and younger.
