A few days ago, I had no idea there was such a thing as “Oncology audiologist” or “Oncology dentist.” But radiation treatment can have real impacts on both hearing and dentistry, and they need baseline measurements and preparatory conversations before getting started.
The audiology visit came first. They led me into a soundproof room with thick walls, and inserted a series of earbuds into my ears and played long series of clicks and tones at high and low tones, with progressive degrees of quietude. Also, tests where I was asked to repeat words back. My hearing is normal, with typical falloff at the high end correlated to my age. Potential effects of radiation would probably be either tinnitus or mild hearing loss. Possible future hearing aids if that does come to pass, but it’s rare. Not much to say here.

The Dental Oncology visit was more intense. I’ll definitely need fluoride trays, and to fluoridate nightly during treatment (loss of saliva during treatment means a much higher likelihood of cavities). But why is there less saliva? Because my salivary glands will be irradiated too, and damage to them could be permanent. I should expect a drier mouth for the rest of my life. Apparently, these days they are able to do a better job of targeting radiation so that it has minimal impact on salivary glands. And some people even have pre-surgery to move the glands! That prospect did not come up in my case.
The really scary/new information was that the radiation will also affect vascular flow in the jaw, which will make it impossible for it to heal in the future. That, in turn, means I will not be able to have teeth removed or implants done in years to come. So it’s important to get everything removed now that looks like it might be a problem down the line, and the doctor did find one tooth that seemed to have borderline future prospects. So, on top of everything else, I now have to have emergency dental surgery to have another molar removed, which means it’s going to get even harder to chew and swallow.
Not the news I wanted to hear, but I do appreciate the wisdom of it.
The next morning was to be my final CT scan – the “mapping and planning” one. Unfortunately, when I got there, they told me that we’d have to delay that because the tooth removal would change the structure of my mouth. So now I need to get the tooth extracted ASAP, give it 7-10 days to heal, and then do the final CT scan. Not great.
