Soft-tissue augmentation complications like nodules can arise from filler materials. Bacterial infection causes nodules with degradable gels, while inert fillers may lead to late-onset infections and fibrosis requiring specialist care.

Area of Science:

  • Dermatology
  • Plastic Surgery
  • Biomaterials Science

Background:

  • Soft-tissue augmentation is increasingly common.
  • Filler quality, patient, and physician factors influence outcomes.
  • Long-term adverse reactions include nodules and granulomas.

Purpose of the Study:

  • To investigate the causes of nodules and granulomas following soft-tissue augmentation.
  • To differentiate etiological factors based on filler type.
  • To highlight the need for specialist intervention in complex cases.

Main Methods:

  • Literature review of adverse reactions to various soft-tissue fillers.
  • Analysis of etiological pathways for nodule formation.
  • Categorization of complications based on filler properties (degradable vs. inert).

Main Results:

  • Nodules from degradable gels and polyacrylamide hydrogel are consistently bacterial in origin.
  • Nodules from inert, hydrophobic silicone gel and combination gels can appear years post-injection.
  • These late-onset nodules are often linked to low-grade infections, leading to fibrosis.

Conclusions:

  • The etiology of nodules post-soft-tissue augmentation varies significantly with filler composition.
  • Bacterial infections are a primary cause for degradable fillers, while inert fillers pose risks of late-onset, infection-induced fibrosis.
  • Management of these complications, particularly late-onset nodules, necessitates specialized medical expertise.
