It has been reported to occur in association with a multitude of conditions, including trauma, epilepsy, tumors, stroke, psychoses, and brain surgery. The cases of two patients who became mute in the immediate postoperative period are presented. The first patient developed mutism following removal of a parasagittal meningioma, and the second following removal of a posterior fossa medulloblastoma. It is believed that transient injury may have occurred to the supplementary motor cortex in the first case and to the dentate nuclei in the second case. It is interesting that these two areas are connected via pathways involving the ventrolateral nucleus of the thalamus, and that lesions of this thalamic nucleus can also lead to mutism. It therefore appears plausible that interruption of these pathways may be involved in the pathogenesis of mutism. Although mutism is an infrequent complication of brain surgery, neurosurgeons should be aware that it may occur following removal of lesions in these areas and that it is generally a transient condition.<\/jats:p>","DOI":"10.3171\/jns.1994.81.1.0115","type":"journal-article","created":{"date-parts":[[2009,5,28]],"date-time":"2009-05-28T14:30:38Z","timestamp":1243521038000},"page":"115-121","source":"Crossref","is-referenced-by-count":82,"title":["Postoperative mutism in neurosurgery"],"prefix":"10.3171","volume":"81","author":[{"given":"J.
