Sparing Parotid Ducts via MRI Sialography for Reduced Patient-Reported Xerostomia

Radiation treatment for head and neck cancer can often cause a very dry mouth. This dryness can last for a long time, even after the treatment ends. In our study, we want to see if changing where the radiation is aimed can help with this dryness. If you join, you'll fill out some simple questionnaires and give saliva samples. We'll also check in with you for about a year after your treatment to see how you're doing.
