Hi, I had translab Dec 15. It sounds as if you have losses in your AN ear similar to mine before the surgery.
I used to stroke my earlobes on both sides to test how much I could hear. The sound pick up was soft (skin to skin), always less on the AN side, and of course I expected that. Well after the translab procedure, you can stroke your ear lobe on the operated side and hear absolutely nothing. That is "no hearing".
BAHA transmits sound from the deaf side to the good side through the skull bone wirelessly. After surgery you will be able to tap your skull or neck bones on the AN side and hear that sound. The bone conducts sound.
I have a friend who had a BAHA pin implanted 5 months ago at the same time as surgery. She is wearing the whole BAHA unit now and loves it. She works as main person in charge of office operations for a large company.
No one but you can estimate how this will affect your own lifestyle. I think a working person might feel his/her life impacted a lot by one sided hearing loss.
I am a retired person with a decent social life. But, I am not decided whether I need a BAHA at this time. I find eating out in restaurants and finding a seat that suits me difficult. Also, I find it a challenge to remind people that, "I didn't hear that, I am on the wrong side". Unless I am only surrounded by family and good friends who know about my deafness, I could not cope so well. Lip reading and a lot of head swiveling
will have to become priorities or I am going to need an aid.
