Your styloids/stylhyoid ligament calcifications are quite long. The left side is very curved & it looks more like your stylohyoid ligament has calcified in segments than your styloid elongating. What I can see of your right side looks pretty solid.
As I mentioned in my welcome letter to you, with your very high level of anxiety it sounds like your vagus nerve may be compressed or otherwise compromised by your styloid(s). The curve of your left calcifications is surely putting them in contact with the nerves that are causing your symptoms.
I’m really glad you have an appointment with Dr. Cognetti in Dec. I expect he’ll be able to put you at ease about surgery helping reduce or eliminate the symptoms on your left side, however, with your right styloid being very long as well, there may be symptoms that don’t go away which are those being caused by the right styloid. It’s more common in cases like yours that once one styloid is shortened, the symptoms being caused by the remaining styloid can flare up which makes it seem like the initial surgery didn’t help when in actuality it did. I found that to be true for myself i.e. symptoms from my remaining elongated styloid flared up significantly after the first one was shortened & even caused some symptoms on the already operated on side.
The thing to note is that you’ve lost the lordotic curve in your neck & even have the beginning of a reverse curve. The loss of the proper curve brings your styloids & hyoid bone into closer contact with nerves & vascular tissues in your neck. There are simple exercises that can be done to help restore the lordotic curve but it takes a fair bit of time.
Here’s a link to a discussion thread with information about the proper exercises to help restore your neck curve:
