-for some people the sneeze sensation comes on slowly and there is time to try something to avoid sneezing, such as gently breathing out through the nose(if its not blocked). Even then, sneezing cannot always be avoided.
-for some people, their sneeze typically comes on very suddenly, and there is no way they can avoid it.
-either way, if your sneeze is unavoidable - do not fear it, but ...... do Not try to be quiet, do Not block your nose, and do Not block your mouth: Instead open your mouth and if you can, "vocalize" your sneeze, by saying "ah-ha" or something similar as you sneeze. This will help make sure that most of the air comes freely out through your mouth, rather than getting bottled in, or coming out through the nose. It might mean your sneeze is loud, but better loud than pressurized

Knowing this in the first weeks/months after the op, made me know to avoid sneezing if I could, but when I had to sneeze, I felt a lot less fearful and knew how to do it.
Hope this helps you too.
