Summary

Polydioxanone (PDS) is a safe and effective material for reconstructing orbital floor fractures. This study found low complication rates, including infraorbital nerve issues and motility disturbances, making PDS suitable even for large defects.

Area of Science:

  • Ophthalmology
  • Plastic Surgery
  • Biomaterials Science

Background:

  • Autologous transplants for orbital floor defects carry donor-site morbidity.
  • Nonresorbable implants risk infection and extrusion.
  • Resorbable, alloplastic materials like polydioxanone (PDS) offer an alternative.

Purpose of the Study:

  • To evaluate complications associated with PDS use in orbital floor reconstruction.
  • To assess the prevalence of ocular motility, infraorbital nerve sensibility, and globe position issues post-PDS surgery.

Main Methods:

  • Ophthalmologic and clinical exams on 194 patients before and after PDS orbital floor reconstruction.
  • Evaluation at 2 weeks and 6 months post-surgery.
  • Analysis of defect sizes (<1 cm², 1-2 cm², >2 cm²).

Main Results:

  • Reduced ocular motility decreased from 31% pre-op to 5% at 6 months.
  • Infraorbital hypesthesia reduced from 62% pre-op to 18% at 6 months.
  • Enophthalmos decreased from 5% pre-op to 2% at 6 months.

Conclusions:

  • Polydioxanone (PDS) is a suitable alloplastic material for orbital floor reconstruction.
  • PDS demonstrates acceptable low rates of infraorbital hypesthesia, motility disturbances, and enophthalmos.
  • PDS is effective for orbital floor defects exceeding 2 cm².
