I think I just answered this on another forum question but I will reproduce the answer on this inquiry.
C1-2 arthrosis (arthritis or wear of the joint surfaces) is a painful condition that causes base of skull pain and pain that radiates up into the ear region. The pain increases with motion and can wake you up at night.
The diagnosis (and potential management of this disorder) is facet blocks of these joints. A diagnostic block (pain relief for the first three hours) confirms the diagnosis. Hopefully, long term relief can occur with the steroid included in this facet block.
If only temporary relief is noted, a fusion of the C1-2 joint generally will give relief. There might be some loss of range of motion (rotation of the head on the neck) as a consequence of this fusion but the trade-off is pain reduction.
This injection needs to be performed by a skilled and experienced injectionist, not someone who has limited experience with this area as it is technically demanding.
