The efficacy of electromagnetic navigation and endoscopic technique in orbital foreign body extraction

Abstract

Objective To investigate the efficacy of electromagnetic navigation and nasal endoscopic technique in orbital foreign body extraction. Methods The data of 2 cases of orbital foreign body from Feb.2017 to Apr.2017 were collected and analyzed retrospectively. They underwent extraction surgery with electromagnetic navigation and endoscopic technique. The localization of foreign body during operation, complications and features of foreign body were observed and analyzed. Results The optic nerve, other anatomical points and ocular foreign body were located accurately during the surgery.All foreign bodies were extracted successfully, no complication happened. Conclusion The application of guidance and positing of navigation system and nasal endoscopy system in orbital foreign body extraction surgery can make the position of the foreign body quickly located. It can increase the safety and accuracy of operating, decrease surgical complications. Key words: Foreign body, orbital; System, navigation, electromagnetic; Endoscope, nasal
