Patient's Query

Hello doctor,

I had my radiation treatment three months ago with 60 Gy on 3D-CRT, and I have less saliva formation in my mouth. I am concerned about when it will go away. Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

From your reports (attachments removed to protect the patient's identity), I can make out you had oral cavity surgery followed by postoperative radiation therapy. In such a scenario, due to radiation therapy affecting your parotid salivary gland, there will be decreased taste, altered taste, and dry mouth (less saliva). Only partial recovery will happen and will take about six months. But some amount of dry mouth will be permanent. I suggest you take saliva substitutes.

I hope this helps.

Thank you and take care.

Patient's Query

Hello doctor,

Thank you for the reply.

Will saliva reach the optimum level, meaning I can eat food without using water or any fluid as a substitute?

Please help.

Hello,

Welcome back to icliniq.com.

I read your query and can understand your concern.

It may not reach the same level as before. You have to wait atleast six months for recovery. Even then, complete improvement may not happen.

I hope this helps.

Thank you and take care.
