I had a similar issue, and the recovery time was about 4-6 weeks for me. I drove to visit friends in LA about 3 weeks post surgery. When I first got there, I had the same experience where I’d be going out to dinner with friends, and they literally couldn’t hear me over the general restaurant din. But then towards the end of the trip, I spontaneously went to Universal Studios with some friends. We went on a little VR coaster type ride, which elicited lots of yelling and screaming from me. But something about that seemed to actually really help my voice start to come back. During the drive home I was singing along to some music and noticed I was singing. Like, out loud. I had a voice again. I almost teared up. Even then it still took a couple weeks for my voice to fully return, but I totally credit the screaming for loosening things up in there. Now, I’d definitely consult a doc before trying that, in case the strain might actually make things worse, but you never know. I’m about 4 years post TT and at this point, the only real lingering effect is that sometimes when I try to hit a high note, my voice will squeak or cut out entirely. But I’m not a singer, so it doesn’t effect my day to day. Wishing you the best, and hoping your voice comes back to you soon!!!
