Neuronavigation System in Intracranial Lesion Microsurgery

The neuronavigation system has been applied for microsurgery in 50 cases of intracranial lesions since January 2003.The lesions and the surrounding structures were located accurately with mean registration error (2.4±0.4) mm.Total removals were achieved in 46 cases(92%).The postoperative complications were found in 5 cases(10%).The durations for operating and staying in hospital,were shorter in cases under neuronavigation microsurgery than those under conventional surgery.It is indicated that,the neuronavigation system is accurate in preoperative plan and real-time orientation of intracranial lesion microsurgery;thus,it increases the radical rate of intracranial lesion microsurgery with favourable micro-invasive outcomes.
