Patients often ask me - Do you use a blunt cannula for the tear trough?
Blog Post October 8th, 2018 - by Dr. Ryan Greene
I answer that I have always used a needle instead, for multiple reasons. In my opinion, the needle technique is more precise, as I am always in the correct plane, and I know exactly where I’m placing the filler. With a cannula, the filler is often placed in an incorrect plane (too superficial and not deep enough). In my practice, I often see patients treated elsewhere who had filler placed incorrectly using a cannula; this can create puffy, lumpy filler below the tear trough.
