Image-Guided Endoscopic Combined With Deep Lateral Orbitotomy Removal of a Small Foreign Body at the Deep Lateral Orbital Apex

摘要

To remove a small foreign body located at the deep orbit apex presents an extremely challenging problem. Small foreign bodies located in shallow lateral orbital and nasal orbital apex have been reported successfully removing in endoscopic surgery with the help of surgical navigation system. Here, the authors first describe successfully removal of a small foreign body at the deep lateral orbital apex with the help of image-guided endoscopic. A 56-year-old man presented with blurred vision and eye movement pain of the left eye while grinding metal 4 days prior to admission. A computed tomography scan showed a small metallic foreign body lodged in the deep lateral orbital apex. The foreign body was smoothly removed without any complications by endoscopic surgery under the help of surgical navigation system combined with deep lateral orbitotomy. Eye movement pain was disappeared and visual acuity was improved after surgery.
