First of all welcome to the group.
Being that I have been down the same road with my facial PWS I know exactly what frustration you have with doctors. It took me a very long time to even find a plastic surgeon to even consider to try surgery.
If you are considering getting another opinion I would recommend my plastic surgeon who is Dr. Milton Waner. You can find his contact info in the resource section above. He resides in New York City.
Also, to maybe get a quicker response from Dr. Waner or Dr. Levitin (Dr. Waner's partner) on what they think options you might have. You can contact Dr. Levintin directly using the link on the front of this website. He is the "ask the sergeon" If you email him pictures and description of the VM he would be able to give you his opinion, or recommend you to go in for an appointment.
I hope this will point you in the right direction. If you have any other questions please ask.
Talk to you soon.
