Summary

Absorbable rigid fixation using polylactic acid-polyglycolic acid copolymer plates and screws effectively treated maxillofacial trauma. These implants provided stable fixation for bone healing and were absorbed without complications.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Maxillofacial surgery

Background:

  • Rigid internal fixation with titanium plates is standard for maxillofacial trauma.
  • Concerns exist regarding long-term presence of permanent fixation hardware.
  • Absorbable fixation offers potential for complete resorption after bone healing.

Observation:

  • Four patients with maxillofacial trauma received open reduction and internal fixation with absorbable polylactic acid-polyglycolic acid copolymer plates and screws.
  • Coronal computed tomographic (CT) scans were used for pre- and post-operative assessment.
  • Clinical follow-up was conducted to evaluate outcomes.

Findings:

  • CT scans at 6 months post-repair demonstrated adequate fracture reduction and osseous healing.

  • The absorbable fixation system provided stable support throughout the healing process.
  • No significant sequelae were observed during clinical follow-up.

    • Implications:

    • Absorbable rigid fixation is a viable alternative to permanent hardware for maxillofacial trauma.
    • This technology may eliminate the need for hardware removal surgeries.
    • Further research could expand the application of absorbable implants in craniofacial reconstruction.
