Glycerol injection

BMJ Group Medical Reference

Doctors call this operation a percutaneous glycerol rhizotomy. It is done under a short-acting general anaesthetic, so you'll be asleep during the operation. You probably won't need to stay in hospital afterwards.

The doctor puts a thin needle through your cheek and through an opening in your skull, to the point where the three nerve branches join. He or she then injects a small amount of a chemical called glycerol into the space around the nerve. This is to damage the nerve and block pain signals. [61]

This operation can be repeated if it doesn't work. You are likely to be left with some permanent numbness or tingling in your face afterwards. [61]
