I am so sorry that you have to go through this! It is a odd that the hyaluronic acid has lasted this long and has been refractory to hyalase injection. Perhaps as a result of the injection you have formed little cysts that respond to the coritsone injection but then return. I like the idea of acne surgery (incision and drainage) if possible. Are these bumps blue as would be with hyaluronic acids or skin colored as cysts?
Say sayonara to your lumps
If it truly was hyaluronic acid that was injected, then it should be superficial in the skin. A small puncture with a #18 gauge needle and pressure should be able to squeeze the material out (I have seen this in a few patients after a year). Do not attempt this yourself, have a trained physician evaluate the situation. In Chicago, I might visit Steven Dayan, MD. Good luck and be well.
Lumps after fillers like Juvederm, Restalyne Voluma or Radiesse
Fortunately side effects from cosmetic fillers are quite rare. In my practice, I often get referred patients who do have complications, or had a suboptimal outcome.
Lumps are generally the result of filler placed improperly, or too superficially in the tissues. These are noticeable right away and resolve either with injection of hyaluronidase to dissolve the filler, massage, or time.
As your lumps appeared months after and are persistent years later, I think it is highly unlikely that the problem is hyaluronic acid. It sounds like you have a more rare complication where a granuloma forms. Essentially this is a form of a sensitivity of your body to the product.
I would try kenalog mixed with 5 florouracil (5 FU) injections first. 5FU is very effective against scar tissue and does not risk dermal atrophy. If that failed, I would attempt micro excision combined with lasering of the scars to give optimal outcome.
I wish you the best of luck
Complications after cosmetic filler treatment
All good feedback from the panel members. As most suggested, it is highly unlikely that you were injected with a hyaluronic acid dermal filler. If you were, the product would not last this many years, it would have responded to hyaluronidase, and it would be a rare case wherein a body would respond with inflammatory nodules as yours has done with HA dermal fillers.
On a sidenote, one panel member mentioned that, to avoid potential adverse reactions from steroid injections, you must have a physician perform the treatment. It should be noted that there is always a potential for a negative or adverse side effect with intralesional steroid injections even with an experienced physician. Only you and an experienced practitioner can decide if the potential benefits outweight potential negative/adverse side effects.
Regardless of your decision, make certain you choose a practitioner that outlines all viable options with benefits vs. potential negative outcomes. You may also want to request (if you haven't done so already) a copy of your medical records from the physician that injected you. There should be a record of the exact product used, lot number, expiration date, etc.
Hyaluronic acid injectables were not available six years ago
Six years ago, the only FDA approved products in the US were collagen based. These products were Zyderm, Zyplast, Cosmoderm, Cosmoplast and a now discontinued product called Dermalogen. While these could have caused lumps, it is extremely unlikely that they would cause such lumps like you are describing.
Sadly, you were probably injected with Silicone, which is NOT approved and has never been approved for facial injections. This is the reason to only have FDA-approved material injected into your face and, furthermore, to avoid anything that promotes itself as permanent or semi-permanent.
Ones to avoid now that are, indeed, FDA approved are Artefill and Sculptra. These can cause some very concerning problems. Others that are undecided/jury out are Radiesse and Evolence. While you can certainly have them done, they don't have the track record yet of Restylane, Perlane and Juvederm.
You need to get a second opinion from a dermatologist in your area with a good reputation.
Perhaps you need a biopsy
You might consider having one small area sent to a dermatopathologist after having a small biopsy. Perhaps under the microscope he/she could determine what is causing this. It is unlikely to be a hyaluronic acid filler acting like this...
Probably not the HA anymore
You seem to have a very good grasp of the complexity of your situation. I would doubt that there is any hyaluronic acid left after 6 years and that the problems you are having are more from cysts under the skin. Excision of these, while leaving a small scar, is usually less conspicuous than the bumps themselves at conversational distance.
It is also possible that what you had injected was actually not HA. Back then people were using some more permanent fillers like Artecol (Artefill) and liquid silicone. These have been associated with granuloma formations years after treatment that are very difficult to eradicate.
I would recommend getting your medical records and confirming what you had injected because a good doctor will specifically record that in the chart. Nowadays, we even place a sticker from the syringe directly in the patients chart.
Although you think it was a hyaluronic acid product it may have not been. If it was, then it should have dissolved unless it was extremely superficial and in that case a small incision with a needle can express the product. If it was a granulomatous reaction to product, then the only way to get rid of it would be excision. All other permanent type products like Artefill or silicone can only be removed by excision.
Anti-inflammatory medications for treating filler injection lumps
Silicone injections can contribute to long term inflammatory reactions that can cause disfiguring nodules and lumps subcutaneously. The lumps and nodules should be treated accordingly with anti-inflammatory medications that reduce the inflammation and edema surrounding the foreign bodies. These can be applied subcutaneously, or topically depending upon the zone of inflammation.
Atrophy can be induced if the subcutaneous injection of corticosteroids are not performed by an experienced physician. A silicone protocol should be employed to minimize the risks associated with this procedure.
