@Alittlebigger Thank you for sharing.
Best wishes to the patient whose story we have read by his posts on this site.
Can you please clarify the statements related to injections “too deep”? Where was this patient injected at? My understanding is that the only proper injection location (plane) is between the two fascia walls.
If this is so critical why do more injectors not use ultrasound to confirm the right plane?
Thank you.
I got a chance to sit down with Dr. Carney and chat with him about your questions. Here's a transcript of what he had to say:
"Well, let's talk about the ultrasound first. Ultrasound of the penis really only works when the penis is erect. That's why, anytime we do an ultrasound on the penis, for Peyronie’s, or ED, or whatever, we always give them an injection, to have an erection.
So an ultrasound is really only good to measure the arterial flow, or a venous leak. But think about it, if you have an erection that squishes together all the layers of the penis because the body of the penis is so erect, the layers under the skin, and on top of the body of the penis, they get squished together, so you actually cannot see the layers on an ultrasound. So an ultrasound would not help an injector put it in the correct location.
So what is the correct location? Well, let me answer the question first that says, um, Please clarify what is meant by “too deep.”
Too deep. The deepest fascia layer is the Buck’s fascia. B-U-C-K-S, fascia.
Immediately below the Buck’s fascia are the nerves, the veins, and arteries. You cannot inject it deep to Buck’s fascia. And you really shouldn't inject it even directly on top of Buck’s fascia, because that can still compress the blood supply.
So, anything below Buck’s fascia or even, immediately on top of Buck’s fascia, is too deep to be injecting because it risks vascular damage. If someone gets too much PMMA, that is also putting that compression against that neurovascular bundle, compressing the vessels together.
The only way to know definitively where to inject the penis is to have performed literally 100s of 1000s of operations on the penis, where you actually deglove the penis. Or you actually reveal a portion of the penis, or you do surgery for Peyronie’s disease. Or you do surgery for urethral strictures. Or you do surgeries to correct a broken penis if they break their penis.
The only way to fully understand the fascial layers and know exactly where you are is to have done 100s of 1000s of operations on the penis. So if you think about the penis being put together like an onion in layers, to where you have actually opened the penis up and separated those layers and you understand the layers.
Someone who has not done thousands of surgeries on the penis, so a family practitioner, a general practitioner, a DO who is not a urologist, anybody without that level of penile surgical experience does not truly understand those layers. They have not lived in that anatomy. And if they have not lived in that anatomy, then they do not really know where they are putting the filler."
