Mathilda,
Welcome to this forum! I didn't find it until about six months after my AN surgery, but have been so very impressed with the people who post here -- you'll learn an amazing amount of information and, of at least equal importance, will be quite inspired by the courage, insight, and resourcefulness of those patients who've had to deal with a variety of issues, some temporary and some of longer duration.
I had my AN surgery at House/St. Vincent's Medical Center just this past January (2008); I think you'll be pleased with your decision to go there ... although as you can see from this forum there are many, many other surgeons and hospitals who are true champions in the AN universe as well. If you're not familiar with southern CA, I hope you'll have enough time in Los Angeles prior to your surgery to take in some sightseeing -- there's a lot to see and do out there, and I found it to be a wonderful distraction from the upcoming hospitalization!
Following my surgery (I had the translab procedure) I was very comfortable sleeping on my non-AN side as well as on my back. As Jan mentioned in the previous post, you should be able to have a normal conversation once the anesthesia has worn off. I don't remember talking that much during the 24 hours in ICU following the surgery -- other than constantly asking for ice chips! I had instructed my husband to ask me some semi-complicated questions as soon as he saw me in recovery so that we would know if my brain had survived; he swears he asked me some and that I answered them, but I don't remember! You should certainly be able to enjoy some visiting once you're in your regular hospital room (all the rooms at St. Vincent's are singles, by the way); you will want to sleep a lot, too -- since, as Jan mentioned, you will be experiencing major bouts of fatigue. I was fortunate not to have experienced any visual, facial, or balance problems following my surgery, but as you can see from the forum postings, there's a broad range of post-surgical responses. I found the nursing staff to be very helpful and responsive, and you can rest assured that they'll do their best to keep you as comfortable as possible.
We were quite happy with Seton Guest Center -- it's not luxurious by any means, but it's more than adequate and reassuringly close to both the hospital and House Ear Clinic! Each floor has a "commons room" -- sort of a living room/dining room combination; the guest rooms have a small seating area and kitchenette as well, so there should be enough room for your granddaughter to roam around! You'll have access to the hospital cafeteria while at Seton, and you can either eat in the cafeteria or bring your food back to Seton. We thought the food was good (certainly by institutional standards!) -- lots of fresh fruits and vegetables when we were there in January.
You didn't mention it, but I'll comment on what will be a long plane trip back home for you --- assuming that you're not planning on a long convalescence here in the U.S. I live on the East Coast (New Jersey) and flew back home without any problem ten days following my surgery. House won't let you fly before you're ready ... but I think the 10 day timeframe is fairly common .... and I remember that a couple of patients flew home from there even sooner.
Very best wishes as your surgery approaches! You will be in absolutely wonderful hands and will receive excellent care.
