Welcome to the discussion forums. I'm sorry to learn of your many post-op issues but, as previous posters have indicated, these complications can and do arise in some AN post-surgery patients. Although you seem to be improving and coping, the facial pressure is clearly a problem . Frankly, I have no suggestions on how to alleviate that but I would consider consulting your doctor and letting him know that this is ongoing and painful. Don't ever 'suffer in silence'. Your equilibrium may never return to what it was before your surgery but, with time and work on your part, it should continue to improve, if only slightly. The hearing loss is, unfortunately, very likely permanent. However, there are Bone-Anchored Hearing Aids (BAHA) available that are a tremendous help to those suffering from unilateral hearing loss, as you are. The tinnitus is also not likely to disappear, but it may subside or, as I have, you'll get used to it and be able to 'tune it out' most of the time. The fatigue you feel is fairly normal because your brain is working hard just to keep you balanced and functioning. That may improve with time, although because you're almost 5 years post-op, it may not be a huge improvement from what it is now. The other issues you're suffering with (metallic taste, facial weakness, eye problems) can probably be addressed by specialists and some relief could be available for you. However, you'll have to ask your doctor or, as I recommend, be your own advocate and make appointments with doctors that specialize in facial reanimation and other disciplines that affect your situation.
I trust that our many members will add more to this thread that may be useful to you but again, I want to extend my welcome and hope for better days in your near future.
