I have the exact same question as the original poster. I can actually feel my elongated C7 transverse processes in my neck, and my incredibly tight and painful scalene muscles seem to stretch around them. But the vascular surgeon at Stanford just wanted to do the standard scalenectomy and first rib resection on me – he was not familiar with surgery just for the transverse processes.

So if anyone can answer the original poster's question, you may be helping out a lot of us.

1) Has anyone had surgery to shorten their transverse processes?
2) If not, is anyone aware of a doctor who has experience with this specific surgery?
