Which type of Cannula is best for fat transfer - open or closed? And why?

Not sure what an open cannula is so I will just say that fat transfer to the face is done with pretty small 0.9 or -0.7 mm cannulas with a blunt tip and the opening near the end.  Fine cannulas require fine control and fat is usually injected with a 1 cc syringe.For other areas, there are many, many cannulas, but in general they have a blunt tip and the fat comes out the side of the cannula through one or more holes.

Cannula type for fat transfer depends on the application - are we talking about fat transfer to the face, breast or body ? All of these regions can be treated with fat transfer.

Thank you for your question. I am assuming the lack of answers come from the lack of clarity in the question. What kind of fat transfer are you referring to? What area of treatment? I prefer to use fat injection cannulas from Tulip, which are blunt-tip, side-open cannulas made specifically for fat grafting. Maybe clarify your question or why exactly you are wondering about this question and you will get more responses.Good luck!
