I am sorry I did not even see this topic on the group. I do not know how I missed. Thanks for reposting it.
I am 23 with facial PWS.
When you say inserting a laser into the VM are you meaning with the regular PDL or a different kind of laser?
The reason I ask is because of the way you worded it. If it is different I would suggest do some more research on it. If you could get the name of the laser they would use (if different)The doctors office could tell you for sure if you do not know.
Also, where are you located? Someone on this group might have seen your current doctor or someone in that area and they might be able to share on this subject.
The area that is swollen that your doctor thinks is a VM could you discribe it a little more?
Is it the same color or darker. PWS can grow (in my case). Does it have little bumps on it?
It could be the start of bleps or cobleing.
I am not a doctor so this is just my opinion. You could sent a picture to the PWS expert on the front of this website. If you are interested in see how my PWS grew you can see it on my website www.hankspws.com
You can also see what it looks like now after I have had three plastic surgeries on the areas that grew. Dr. Waner in NYC did a very good job removing my excess tissue from my PWS.
Hope this helps, and good luck with the ultra sound.
