Abscess after a procedure: what it is and warning signs
Quick facts
- Definition
- A localized collection of pus in the tissue, surrounded by an inflammatory reaction.
- Most common cause
- Bacterial infection, usually linked to a lapse in asepsis or to biofilm.
- Signs
- Pain, warmth, redness, hardening and, sometimes, fluctuance or fever.
- When it appears
- It can appear days or weeks after the procedure, and later in cases of biofilm.
- Management
- Assessment by the qualified professional, without delay, according to the rules of their professional council in Brazil.
An abscess is a localized collection of pus in the tissue, formed when the body walls off an infection. In orofacial harmonization it is a rare complication, but one the professional needs to be able to recognize, because treatment depends on acting early and on telling an abscess apart from other causes of lumps in the face.
How does an abscess arise after a procedure?
The most commonly cited cause is bacterial contamination: poorly prepared skin, contaminated material or handling without proper asepsis. Another route is biofilm, a film of bacteria attached to the injected material, which can stay silent for weeks and reactivate later.
There is also infection from a neighboring source, such as a herpes lesion, inflamed acne or an untreated dental problem in the area. That is why the medical history and a skin exam before the procedure are part of prevention.
How can it be told apart from other causes of lumps?
| Condition | Usual clues |
|---|---|
| Swelling | Diffuse puffiness, without intense pain, that improves over the days |
| Bruise | Purplish color, evolving with color changes |
| Inflammatory nodule or granuloma | Persistent hardening, usually without signs of acute infection |
| Abscess | Increasing pain, warmth, redness, sometimes fluctuance and fever |
Why does it matter in planning?
Hyaluronidase comes to mind for reactions to hyaluronic acid, but it does not replace assessing for a possible infection. The practical point for the clinic is to tell the patient in writing what is expected and what is not, and to record the contact in the patient record. More extensive cases may be classified as infectious cellulitis.
Also known as: purulent collection, localized infection.
Frequently asked questions
Is every painful lump after filler an abscess?
No. Swelling, bruising, an inflammatory nodule and a granuloma can also form lumps. Pain, warmth, increasing redness and progressive worsening are the signs that raise suspicion of infection and call for assessment.
