Abstract:
In the oral and maxillofacial foreign body (FB) extraction surgery, computer-aided navigation technical surgery is minimally invasive and safe, and can improve the accuracy, especially for areas with relatively complex and dangerous anatomical structures. A total of 11 patients, including 8 males and 3 females, who underwent the extraction surgery of FB from oral and maxillofacial regions using computer-aided navigation technical surgery were reviewed. According to the positional relationship between the maxillofacial region and the bone tissue, the FBs were divided into 3 categories: FB in the bone; FB aside the bone; and soft-tissue FB. During the operation, the BrainLab Navigation system was used to observe and guide the operation in real-time to evaluate the effectiveness and accuracy of computer-aided navigation technical surgery in the extraction of FBs from the maxillofacial regions. The FBs were successfully located and removed in 11 patients. No adjacent nerves, blood vessels, and other important anatomical structures were injured during the operation. The postoperative function and shape were not significantly affected.
