A retrospective analysis was conducted on the types，quantities，and removal methods of foreign bodies in the patients.

Results

During the surgery，the position of foreign bodies in sixteen patients was real-timely located by using computer-assisted navigation which showed accurate registration and low mistake.All the foreign bodies were successfully removed with minimal surgical trauma.
