There are mixed reviews about the different surgeries available to people with sleep apnea. I would suggest looking at a couple of different forums dedicated to sleep apnea to get the answers you are looking for. One forum is on the http://www.cpap.com website, looking at their home page there is a link to it at the bottom left side of the page. Another one is http://www.apneasupport.org/index.php Both sites have a search feature so you can find the answers you are looking for there.
Some of the surgeries available are extremely painful and don't have a very high success rate. It could depend on the severity of your apnea, but I know in my case it's not a viable option. My doctors have been very negative about the surgery and I have had wonderful luck using the cpap.
Hope they can find the answers they are looking for.
