Area of Science:

  • Ophthalmology
  • Plastic and Reconstructive Surgery
  • Biomaterials Science

Background:

  • Orbital defects present significant reconstructive challenges.
  • Traditional repair methods often involve autologous grafts with associated donor site morbidity.
  • There is a need for reliable alloplastic materials for orbital reconstruction.

Purpose of the Study:

  • To evaluate the safety and efficacy of porous high-density polyethylene (PHDPE) in repairing orbital defects.
  • To document surgical outcomes and complication rates associated with PHDPE use.

Main Methods:

  • Retrospective case series design.
  • Involved 170 patients undergoing surgical repair of orbital defects.
  • Utilized porous high-density polyethylene (PHDPE) for reconstruction.

Main Results:

  • A low overall complication rate of 6.4% was observed.
  • Specific complication rates included infection (1.8%) and persistent orbital malposition (3.5%).
  • No cases of material extrusion were reported (0%).

Conclusions:

  • PHDPE is a safe and effective material for orbital reconstruction, yielding excellent functional and cosmetic results.
  • This study represents the largest case series on PHDPE for orbital defects.
  • Clinical practice has shifted towards minimizing autologous grafts in favor of PHDPE, thereby reducing donor site morbidity.
