Mary:
My jaw reconstruction was about 5 years ago, the chin implant approx. 19 months. I don't think that removing the implant will decrease the sensation though. My understanding is that the discomfort comes from the nerves being stretched and then recovering and healing...something that you would probably aggravate further if you had more surgery to remove the implant.
I had the most problem after the jaw reconstruction and I believe that the doctor was able to give me medication to ease it (sorry, but for the life of me I can't remember what it was), after the implant I was pretty much used to the sensation, so I did not need anything.
It drove me nuts at first too, but it should get better. It would disappear for awhile and then for some reason (I never was able to figure out what triggered it) it would start buzzing again. Both the insensity and the duration should lessen as the nerve recovers. At the time of the jaw reconstruction I also lost some sensation, it has never returned fully but the rule of thumb according to the maxofacial surgeon was that it can take up to a year for full nerve recovery.
My understanding is also if the implant was put in thru your mouth (via a cut inside your bottom lip) that the chances of nerve damage is higher than if the cut was made under the chin.
I hope that you got some relief from the Dr. today.
