Transient loss of speech followed by dysarthria after removal of posterior fossa tumour

Abstract

The authors report three children who suffered transient loss of speech during six to eight weeks following removal of a large midline cerebellar tumour. None manifested speech difficulties immediately after surgery, but all developed mutism within 24 to 48 hours. The speech of all children slowly but completely recovered, after a period of severe dysarthria. The re-organization of speech functions is discussed in relation to the functioning of musculature.
