I fully agree with Boppie. My SSD was the result of sudden sensorineural hearing loss - literally woke up one morning 100% deaf on one side. So though the cause is different, the result is the same. Fortunately, I only dealt with relatively minor balance problems, and some minor facial numbness, both of which resolved over a few months (the balance faster than the facial numbness). I ended up with a TransEar, partly due to cost (insurance wouldn't pay for either a BAHA or Transear - or a CROS, for that matter). I didn't like the idea of something in both ears (the Cros), and drilling into my skull - though generally successful without complications in most cases - just wasn't something I wanted to do even if I could afford the BAHA. I've had a large number of problems with the TransEar, many the result of issues with the audiologist and her attitude toward the device, and limited willingness to work to get the programming done RIGHT (the company - Ear Technology - is quite willing to work closely with audiologists, even doing over-the-phone help during the actual programming of a patient's TransEar). There were also a high number of electronic/mechanical problems with my TransEar that do NOT seem to be representative of the device, according to what I've read here.
At two years, I highly recommend doing something about the SSD. While subtle at times, the difference between having my TransEar and not having it is major! I was recently without it for 3 weeks due to a breakdown just before the holidays, and I could not wait to get it back. The difference with vs. without is not subtle at all - only the "apparent" assist it gives seems subtle while you're wearing it. Without it, you immediately realize just how much it helps once you get used to it. I just hit the 1 year point this week with the TransEar, and am very glad I stuck it out.
For anyone just out of surgery (or very recent SSNHL), I personally recommend getting used to SSD for a couple or three months. There's an adjustment period, essentially comprised of the five stages of grief that people go through with the loss of a loved one, or even the loss of a limb. To suddenly lose all directional capability, often be unable to comprehend what someone is saying even though you hear their voice loud enough, etc. - that takes some getting used to. I sincerely believe that if I'd tried the TransEar within the first 3 months or so, I probably would have sent it back within the 1-month evaluation period. I needed to get used to what SSD was like before I could appreciate the difference between it and having the TransEar (I've read some posts from BAHA users who also report that the difference can seem subtle at times - until you DON'T have it on/in, then you notice the difference in very UNsubtle ways).
I'd say, "Go for it, and go for it now!" You owe it to yourself. You're likely to be less anxious, less irritable, easier to be around for others, and just plain enjoy life a whole lot more. Unlike Boppie, I haven't noticed any directional ability at all, but I'd still not be without the significant difference having this device gives me.
