Effect of Navigation System on Removal of Foreign Bodies in Head and Neck Surgery

Foreign bodies retained in oral and maxillofacial regions include different types and properties. Road traffic accident is one of the major causes of the maxillofacial trauma. Foreign bodies can cause direct or indirect damage to the body, even life-threatening. It is a demanding procedure to detect the accurate position and implement surgical removal of the embedded fragments in the soft tissue in clinic. Usually, foreign bodies are close to important structures such as the head and neck region with limited intraoperative visibility and anatomical intricacies. Therefore, the key to remove foreign bodies in head and neck surgery is precise localization and reasonable surgical approaches. The authors reported that the foreign bodies adjacent to large vessels in a case were successfully removed assisted by AccuNavi-A surgical navigation system.
