I think I might be able to clear up the needle vs. cannula issue...or at least give you my perspective from having done this with
Radiesse.
Injecting with a cannula is 10x harder...particularly for
Revision procedures.
The principle is that you \"make a hole\" with the needle, and then you insert the cannula and inject. However, in reality, it\'s hard for the hole to stay open, especially with fibrosis already in there. A needle can be very accurate and cut through the existing fibrosis or filler, but you just can\'t burrow through existing
PMMA fibrosis with a cannula. It\'s very inaccurate as to where the
PMMA goes unless you spend a lot of time with it. That\'s why my
Radiesse injection that I did took 4 hours (to have such good results, I might add - thank you). But, it was the hardest thing to do because i must have stuck myself 20 times for 3-4 useful holes. It is much less precise to do corrective work with a flexible cannula. Even Dr. C used a needle on me in that one gap area that always comes back 2 days post procedure (somewhere in my progress reports I show it and he always fixed it). He was very clear about the embolization risk and said, if you feel a sharp pain, tell me immediately. He went very slow, and certainly injected it as he withdrew (never inject as you push in). He said, You\'ll feel some pain,but not sharp. He didn\'t even want to numb the area much. He put 2 cc of metacrill directly into the side of the shaft with a very thin needle and it was fine. So, yes, it can be done - and I think even he knows that for tiny area corrections where it is a complex area, a needle is more precise...unless he didn\'t feel like using the cannulas, but I doubt he\'d take a shortcut like that.
The video screen grab posted by hoodle that shows injection into the neurovascular bundle, and that is very concerning , and it seems odd that someone would do that who has medical training. Dr. C stays far away from there when injecting. My
Urologist stayed far away from there when I got verapamil injections, even though my peyronie\'s plaque was right under there (he always entered through a side angle). You are not supposed to go near there with caverject either.Also, with regard to injections, numbing the area makes things even more complicated because the lidocaine adds volume. The other thing, if you use a needle or cannula, you should pull it back to make sure you are not in a blood vessel. If blood starts coming into the syringe, then you need to move elsewhere.
If you do inject into a blood vessel, you may still be ok with the use of nitro-bid paste and hydase (if it\'s
HA). If
Radiesse or
PMMA get in the blood vessel, nitro-bid & warm compresses can help dilate the vessel so that the body can just absorb the particles (if you\'re lucky). But, we have seen photos from journals where urologists have caused total
Necrosis of the penis on here - as well as major
Necrosis of the face from injecting in a blood vessel. The risk should not be minimized! Even with my cannula injections, I still had nitro-bid on hand.
Cannulas from DermaScult are also flexible, which I personally found very annoying. The areas I needed to inject were always hard to get to, and they would just bend out of the way. Needles are never flexible & get to where you are going. I don\'t know where rigid cannulas are sold. Dr. C uses rigid cannulas, but he has a whole custom setup there.
Did that clear anything up?
I don\'t know what the hell is going on w/ the shills. mischiefmkr never seemed like a shill, but now he is? I think he said he had problems with the lumpiness of the
HA at first and was pretty honest about all of it?
