I am totally deaf in my right ear after an Acoustic Neuroma 15 years ago. I don't think they did Cochlear implants on single sided deaf SSD people til recently. There is also a device called a BAHA or bone anchored hearing device which has been used for SSD people for awhile. I myself use a hearing aid called a Transear which is totally removable b/c I didn't want to have any kind of a surgical implant. It is all a personal choice of course, but nothing will make you hear as you once did. It is very frustrating.
