| Abstract |
Objective
Neuronavigation has become an essential tool of neurological surgery. It is possible even small deep-seated lesions in eloquent area could be successfully removed using neuronavigation. We report on our experience of neuronavigation aided removal of space occupying lesions (SOLs) during the past 12 months and discuss the usefulness and limitation of neuronavigation for deep seated SOL.
Methods
From August 2005 to July 2006, we operated 21 SOLs of the deep cerebral or eloquent regions in 19 patients with aid of neuronavigation. The preoperative image registrations were undergone by computed tomography in 14 cases and magnetic resonance imaging in 7 cases.
Results
The range of error between the image on the monitor screen and the real location in the clinical study was within 2.0 mm. The pathologies were glioma in 7, meningioma in 3, other tumors in 2, ICH in 6, AVM in 2, and abscess in 1. Among the 21 SOLs, one case of large ventricular tumor was unsuccessfully resected and was subjected to repeated craniotomy. There were no morbidities related to surgery in the deep cerebral or eloquent areas other than incomplete removal of the tumor in one case of ventricular tumor.
Conclusion
With great usefulness and minimal disadvantages for removal of the deep seated or eloquent regional masses, neuronavigation will be used with increasing frequencies in a variety of complicated neurosurgical operations. |
