he nodules are accumulations of gel in the area of tissue affected by the injection of the filler. They can affect the right anatomical plane of injection or they can be located in another plane. They are one of the most common complications associated with filler injections. They can be classified according to two characteristics:
Usually these nodules (commonly called “lumps”, “balls”, “spots”) appear immediately after treatment. We can distinguish them into two categories: small and large
They are usually not visible and are not painful (or at least very painful). They are slight thickening of gel (due to a slight movement during muscle contraction) and resolve spontaneously within a month of treatment.
They do not cause any aesthetic damage and do not require any corrective intervention. If they persist: hyaluronidase.
They are usually visible (regardless if they create a negative aesthetic effect) and are annoying (they rub against the teeth). They are located internally in the lip mucosa or inside the lip muscle (deep location). They are coarse accumulations of gel, the result of an incorrect positioning of the too superficial gel, an excessive quantity, an incorrect technique or a mix of these causes.
Usually these nodules, also called GRANULOMA or COLD NODULES, are caused by an immune response to some filler ingredients.
A post-filler granuloma forms when our body’s immune system responds to a foreign body that cannot be eliminated physiologically. The incidence is very rare (0.01 to 1.0%) and usually occurs after a latency period, which may last several months or years after the injection.
Usually these nodules are abscesses, related to a local infection after treatment.
