Application of electromagnetic navigation in surgical treatment of intracranial tumors: analysis of 12 cases.
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.


CONCLUSIONS
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.
