Abstract ID: 25-475
Purpose
Foreign bodies of the orbit and eyelid often appear deceptively easy to localize on CT scan. During surgery, however, localizing these foreign bodies may be surprisingly difficult. The author demonstrates techniques which may be helpful in the quest for foreign body removal.
Methods
Three techniques are briefly discussed. 1) Plain x-ray with radio-opaque skin markers 2) Intra-operative fluoroscopy 3) neuro-navigation
Results
Repeated plain x-rays are a low-tech option in a minor surgery setting. However, this approach is time-consuming and laborious. Fluoroscopy or neuro-navigation allow good localization but require expensive equipment and well-trained nursing.
Conclusion
Fluoroscopy or neuro-navigation, when available, may be helpful for intra-operative localization of orbital and palpebral foreign bodies.
