Loss of vocal power

It all started with an SMR of my left nostril when I got laryngitis 30 years ago. I lost my voice and was advised by my GP to have the SMR 'to straighten up the septum.' I was then having opera lessons in the Guildhall School of Music (London). The NHS surgeon said the op would not affect my voice. But it did. I lost my resonance as a result and spent the next 10 years visiting Harley St doctors, and even a famous one in Sydney, to try to get my resonance back. This involved two further operations, each one making both voice and nose worse. Then three years ago (when it was years too late to be a singer) I had to have cartilage grafted from an ear to restore the shape of my left septum.
Now, except for about the first two hours every morning, my voice is constantly dried up or blocked, as though there is glue / catahrr on my voicebox. My once ringing voice has to be forced - which makes talking, thinking and voice modulation impossible. It affects me radically. Apart from constantly inhaling steam, CAN I DO ANYTHING ELSE?
