Will dermal filler accidentally injected into the salivary gland go away with time?

Voluma injected into a salivary gland is an unusual side effect to report.  If it is not bothersome to you, I would just let it go away on its own. If it is a problem your injector can help it go away sooner wt Hyluronidase. 

Thank you for sharing your excellent question.  Voluma will dissolve very slowly over time assuming it was erroneously placed into your salivary gland.  If you are having any side effects that would indicate blockage, best to have the material dissolved with hyalurondiase.  Hope this helps.

This is a hard question that I have never experienced. If only in the duct, it should probably get excreted in the saliva. There will most likely be some in the gland too. This will persist and probably not cause any problems. It is possible it could cause some inflammation though, like parotitis, and in that case antibiotics and hyaluronidase would be needed.

If some hyaluronic acid filler is inadvertently injected to the parotid gland it will gradually dissolve on its own.  Filler can show up on imaging studies as a non specific "area of increased uptake" which would normally be concerning--especially if you did not have filler injected to the area.  It will eventually go away but you can speed the process up with some hylauronidase enzyme injections.  If the duct is blocked it would be best to get the filler dissolved but if it is not problematic it is safe to wait and let your body break it down.
Hope this is helpful.  Best,

Like Dr Weiner, I have not come across this as a tertiary Specialist, and to my knowledge have not injected into the gland. I assume that imaging shows HA in the area? Like others I agree that nothing needs to be done if asymptotic, however if recurrent inflammation is seen, dissolving the filler under antibiotic cover would be sensible. Dr Davin S. Lim. Brisbane.
