Resorbable plates for craniofacial reconstruction can cause complications. Four pediatric patients required surgical removal of these plates due to palpable hardware and bone irregularities after 2 years.

Area of Science:

  • Craniofacial surgery
  • Biomaterials science
  • Pediatric orthopedics

Background:

  • Resorbable plating systems offer advantages over permanent plates for craniofacial reconstruction, especially in children.
  • Potential benefits include reduced risks of plate migration, bone growth restriction, and imaging artifacts.
  • However, the resorption process itself presents unique challenges.

Observation:

  • Four pediatric patients developed palpable and observable resorbable plates for over two years post-craniofacial remodeling.
  • All patients eventually required surgical removal of the plates.
  • Gross examination revealed encapsulated spongy material and underlying bone depression with irregular contours.

Findings:

  • Histopathological analysis showed a foreign-body reaction with giant cells and crystalline material within vacuoles.

  • The resorbable plates did not fully resorb as intended within the observed timeframe.
  • Significant inflammatory and tissue response was noted around the persistent plate material.

    • Implications:

    • These findings suggest potential complications associated with resorbable plating systems in pediatric craniofacial reconstruction.
    • Further research is needed to understand the mechanisms of delayed resorption and associated inflammatory responses.
    • Clinical vigilance and consideration of alternative fixation methods may be warranted in specific pediatric cases.
