Pegging hydroxyapatite orbital implants can lead to complications like discharge and granulomas, though most are minor. Implant infection is the most serious risk, potentially requiring removal.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • Hydroxyapatite orbital implants are common for anophthalmic socket reconstruction.
  • Complications of hydroxyapatite implants have been studied, but peg system issues are less understood.
  • Pegging enhances implant motility but may introduce specific complications.

Purpose of the Study:

  • To identify and analyze complications associated with the pegging system of hydroxyapatite orbital implants.
  • To discuss management strategies for pegging-related complications.

Main Methods:

  • Retrospective case series analysis of 165 hydroxyapatite implants with pegged systems.
  • Data collected included surgery type, implant details, peg system used, and complications encountered.
  • Follow-up duration and treatments for complications were recorded.

Main Results:

  • 37.5% of patients (62/165) experienced pegging-related complications.
  • Common issues included discharge (37%), pyogenic granulomas (30.6%), and peg dislodgement (29%).
  • The most severe complication was implant infection in 3.2% of cases, necessitating removal.

Conclusions:

  • Pegging hydroxyapatite orbital implants can result in various complications, often minor but requiring extra care.
  • Implant infection is the most serious risk, potentially leading to implant removal.
  • Pre-procedure patient counseling regarding potential pegging complications is recommended.
