Hi & welcome to the site!
Has your doctor done many of the surgeries, do they do intra-oral or external surgery? It’s good that they will remove the styloid and the whole ligament , we have info in this section about surgery, links to post op recovery stories and what to expect if you want some more info:

I think we all get anxious about the surgery, especially the no knowing which symptoms will go, the swallowing sensations usually do improve as long as the calcifications are removed along the ligament too…
