Hi, Cobbler,
If they mention cochlear implant, then they consider a chance to preserve the hearing nerve a realistic possibility (although like Jim mentioned not a guarantee) and the tumor being quite small. Usually when doctors consider cochlear implants, they do it for patients who are deaf or losing hearing in both ears. For SSD, when one ear is quite good, BAHA (or its alternative) is better. It gives better performance, and also allows for periodic MRIs, the surgery is a lot simpler and easier and chance of complications is much smaller. A cochlear implant is usually the last resort. One member who ended up being NF2, had surgery on her second AN with the thought that she might have cochlear implant in the near future. However, she did not really need it because miraculously, the doctors were able to preserve her hearing nerve and save her hearing. It is disappointing (to say the least!) when the hearing nerve is preserved during surgery but hearing is no longer usable. Maybe, she will chime in and tell you more about it. Meanwhile, best of luck in your treatment and recovery!
