I think you are still well within the range of normal recovery. Maybe it's just taking your vocal muscles a bit longer to re-contract after being sutured together? I'm sure Jessie will have some answers for you. I remember she told me it was normal for patients to sound almost the same right after the procedure (sometimes even somewhat mono-tone), and that the voice increases in pitch greatly over the next 2 months and then following that a little bit more to the year mark. I doubt you've any reason to be worried about a lacking result!
At first, I remember having to concentrate on pitch pretty regularly because I kept bottoming out at 140-145hz which could have also been due to the botox injection at 1 week post op. Additionally, my brain did not want to initially accept the higher pitch range as normal. Maybe it was indeed the difference of tying off 1/2 of the vocal cords vs 1/3. I did also tell Dr. Kim to air on the side of aggressive, mainly due to worries I had about tracheal shave weakening the voice box. I told him I would be fine if it came out a little higher than average, having a feeling the extra boost would do no harm. Post op after adjusting to my voice, I ended up with a very average result- at least 60hz up "naturally" and 75hz+ easily when thinking about it.
140hz normal speaking to 200hz
162hz consciously raising pitch to 230hz
73hz bottom out to 138hz
523hz top out to 660hz
That is where I am at now. In my case, I haven't noticed a significant change in my fundamental pitch from the first day I could say words, but that is rather rare and may have been attributable to my obsessiveness about recovery
I drank water like a FISH! The water bottle was always near to me and half full for the first 4 weeks post op. It was the only thing I could do to fend off coughing fits from a cold I caught shortly after returning home.
From what Jessie told me, you may not even notice much of a change until you start vocal exercises at 2 months. Hang in there and be very kind to your cords.. Drink a TON of water and try not to make low notes at all. I was kind of afraid to use a lower range at all for fear that it might stretch something or lessen the result.
Either way, the recordings you have posted so far have been great! And I know I'm not alone when I say I am looking forward to hearing more
