Objective: To explore the application and characteristics of electromagnetic navigation in neurosurgical operation.
Methods: Neurosurgical operations with the assistance of electromagnetic navigation were performed in 12 patients with intracranial tumors.
Results: Total removal of the tumor was achieved in 8 cases, subtotal removal in 3 and removal of the majority of the tumor in 1 case. The error in the navigation averaged 1.9+/-0.9 mm and the time consumed by preoperative preparation was 19+/-2 min with the exception in 1 case.
Conclusion: In comparison with optic navigation, electromagnetic navigation offers better convenience and absence of signal blockage, and with a head frame, automatic registration can be achieved.
