Awake Surgery for Nonlanguage Mapping

Neurosurgery 66:523-529, 2010 DOI: 10.1227/01.NEU.0000364996.97762.73

During the past decade, numerous reports have supported the contribution  of awake mapping in surgical removal of brain lesions in eloquent areas, with a significant  increase of the extent of resection while minimizing the risk of permanent deficit—and  even improving quality of life.

METHODS: Most of these awake procedures were performed in patients with lesions in  language areas, to avoid postoperative aphasia. Surprisingly, mapping of nonlanguage  functions received less attention, despite the possible consequences of deficits other than  aphasia on daily life. Visuospatial and cognitive deficits are reported after brain surgery,  because of more objective and extensive neuropsychological assessments.

RESULTS AND CONCLUSION: This review provides new insights into the indications of  awake craniotomies for nonlanguage mapping in surgery for lesions in areas not related  to language processing.
