I've just returned home from having a second nasal endoscopy. Not the most pleasant experience (although there are worse places to stick an endoscope, I assume), but second time round the results were not quite so surprising. It was a similar procedure back towards the end of November that first discovered my paralysed left vocal cord and which led to my first CT scan that found the tumour.
This time, the result was the same: a palsy (paralysis) of the left vocal cord, most likely from nerve damage to the nerve that controls it. I have two options: speech therapy to help my right vocal cord compensate (more than it already is, since the gradual improvement of my voice since October is the result of this tendency); or a surgical procedure to insert a piece of plastic into my larynx in order to turn my left vocal cord permanently 'on'. Non-invasive procedures are nearly always better to try first, so I will give speech therapy a few months and see if there is any improvement before I let them take a knife to my throat.
