Dr. Costantino’s forté is IJV decompression surgery especially where ES is involved. He works together w/ Dr. Tobias who shaves C1 to help prevent a recurrence of the compression & he removes the styloid as close to skull base as possible. Some of the doctors on our Doctors List are a bit more cautious about getting too close to the skull base so they don’t cut the styloids short enough which in some cases doesn’t matter but in others like yours & mine it does.
We have a number of members who have seen Dr. Costantino for styloidectomies with IJV decompression. If you call his office to ask about it, I’m sure they’ll confirm he does.

Re: your platysma muscle, I actually have had trouble w/ mine on the left side since my left ES surgery. It gets Charlie horses, as odd as that sounds, and my skin actually crinkles up when the muscle contracts. It’s not horribly painful but feels & looks weird. Your situation looks to be a deeper muscle that may have had nerve damage & is in a state of constant contraction from that.
Here’s an image of the muscles at the front of the neck so you can see which ones you think might be causing the bulge:
