摘要

OBJECTIVE: Intraopcralive speech mapping has evolved inio the "gold standard" for neurosurgical removal of lesions near ihe language corlex.The integration of neuron-aigalion into a nuillimoclal protocol can improve tho reliability of Ihis lype of opera-lion, bul most systems require rigid fixation of the patient's head throughout the operation. This article describes and evaluates a new noninvasivelv attached sensor-based reference tool, which can replace rigid pin fixation of the patient's head during awake c raniolomies. METHODS: The attachment technique and the resulting application accuracy were investigated under clinical conditions in13 patients undergoing awake craniolonn with intraoperalive mapping of cortic al language sites. RESULTS: Spatial information was used for updating Ihe image guidance by continuously adjusting Ihe image planer relative to the position of the patient's head. The mean registration error achieved with this technique was 1.53 (+-) 0.51 mm (fiducial registration error +- standard deviation.). The system's median application accuracy between dura opening and closure ranged from 0.8 5 to 1.85 mm (position erron. CONCLUSION: I'he use of a reference sensor can replace uncomfortable pin fixation of the patient's head during navigation-supported awake craniotomies. Application accuracy is not affected bv repositioning of the patienl or by unavoidable head movements. Thus, this technique enables full exploitation of the benefits of navigation in a mullimodal operative protocol without the need to rigidly fix the patient's head.
