Craniofacial orbital implants have a low long-term success rate, with most failures occurring late. Meticulous hygiene is crucial for patients considering these implants.

Area of Science:

  • Reconstructive surgery
  • Oral and maxillofacial surgery
  • Ophthalmology

Background:

  • Craniofacial implants are used for orbital prostheses.
  • Orbital implants are placed in irradiated and non-irradiated patients.

Purpose of the Study:

  • To evaluate the success rate of craniofacial implants in orbital reconstructions.
  • To assess soft tissue responses around orbital implants over time.

Main Methods:

  • A 7-year clinical study of 23 orbital implants in 8 patients.
  • Implant success rates and peri-implant soft tissue health were monitored for up to 72 months.
  • Soft tissue health was assessed using a five-point scale at 6-month intervals.

Main Results:

Related Experiment Videos

  • The overall implant success rate was 35%.
  • Soft tissue inflammation was observed in 57.5% of evaluations.
  • Late implant failures were more common than early failures.

    • Conclusions:

    • Orbital implants have a high failure rate, particularly in the long term.
    • Patients must understand the low success rates and the need for diligent hygiene.
    • Careful patient selection and meticulous hygiene are essential for managing orbital implants.
