Hello
I had the misfortune of losing all hearing in one ear in October, 2019. I also lost my ability to balance the same night. It turned out that these were symptoms of an autoimmune disorder and that my nerves had been destroyed/badly damaged. Once I was certain that my deafness was not going away I ordered, and have been wearing Oticon bi-cross aids. The aid on my deaf ear blue-tooth’s the sound to my hearing ear. My husband, on the other hand, has had a similar problem for many years. He uses a Baha (bone anchored hearing aid) which essentially accomplishes the same thing. The sounds go through his skull rather than using blue-tooth. These seem to be the options currently available. Best of luck to you with this.
