Abstract: PURPOSE: To investigate the clinical efficiency of using ultrasonic navigation combined with CT to remove metal foreign bodies in the skull base and maxillofacial region. METHODS: The clinical data of 32 patients were reviewed. The metal foreign bodies were removed under ultrasonic navigation combined with CT. RESULTS: All 32 patients had good results and minor side effects. The foreign bodies were located accurately and removed with short operation time and less bleeding. Among 194 foreign bodies, 36 were removed under navigation ultrasound, 153 were removed under CT navigation; the total removal rate was 97.4%. CONCLUSIONS: Ultrasonic navigation and CT could fix accurately on the position of foreign body, avoiding important blood vessel and nerve injury during operation.
