Can fillers in nasal fold leak into the sinuses? (Photos)

Vollure would typically be placed far more superficially than the bone of the maxilla, which houses the maxillary sinuses.  Even if you had had an older type of anterior maxillary sinus procedure decompression known as a Caldwell Luc, the placement of the filler would be no where near the depth required for such an occurrence.  Most likely, you are experiencing viral or allergy symptoms.

Thank you for sharing your question and photographs. Because sinuses are surrounded by bone it would be next to impossible for fillers to leak into them.  IF you do not see any improvement quickly I would recommend seeing an ENT in consultation. Hope this helps.

Your sinuses are surrounded by firm bone.  Filler cannot leak into the sinus cavity unless it was directly placed there which would be almost impossible to do.  

It is not possible assuming proper injection. This reaction is highly likely to be due to some other cuases. Please contact a qualified provider or a board-certified physician with extensive experience in these procedures.

Dear Realself friend,
Fillers like the HA Vallure can not leak into the sinuses.   Those get injected fairly superficial just under your skin. Even stronger fillers that get injected deeper like Restylane Lyft or the Juvederm Volluma still go above bone and stay there. Your sinuses are covered with bone which is not easy to penetrate. With that said,  sinuses can get penetrated through mouth procedures such as placement of implants or root canals when the roots ate already located in the sinuses.  If you are feeling a funny taste in your mouth and sinuses I would consult your dentist or see an ENT for further diagnosis.   Hope this helps.  
Best,  Dr. Onir
