Hooray for having surgery scheduled. Boo Hiss that it’s scheduled so far out. Have you asked to be put on a cancellation list?
I find it interesting that if you have vascular compression on both sides (as you intimated) your surgeon wouldn’t automatically do a surgery for each side to relieve your intracranial pressure completely especially in light of your CSF leak situation. I had vascular symptoms on my right side but my left side caused the vast majority of my pain. Dr. Samji elected (i.e. didn’t give me a choice) to do the right side first because he felt it was more critical to take care of it due to the thickness of the styloid & the angle at which it was growing. It was 9 months before the other side was done & by the time he took that one out, I was nearly a basket case.
In answer to your question - yes, a given styloid can cause “cross-over” symptoms i.e. pain/symptoms on the opposite side of the body thus it’s possible (but not probable) that the left side symptoms will become less after your first surgery. In bilateral cases, it’s very difficult to tell which side is causing which symptoms until both styloids/calcified ligaments are removed. Additionally, once one side is resected, the other side often ramps up whatever symptoms it was causing. When this happens, people often feel the first surgery “didn’t work” because the symptoms aren’t all gone when, in fact, some symptoms are gone & the fault lies w/ the remaining styloid. Once it’s removed, more complete ES recovery occurs.
