Sass and colleagues in contrast observed impairments after total partial callosotomy raised concerns regarding motor function language particularly those patients with dissociation of hand dominance. As would be expected outcome paralleled neurological improved seizure control resulted in greater alertness and attention memory most cases. William T [...]

Additionally significant care should be taken when tracing and dividing the callosomarginal pericallosal vessels noted above with extension vary significantly their vascularity. Similarly the children were somewhat clumsy when performing bimanual operations during first days following surgery but recovered within few weeks. While bilateral anterior thalamic DBS presently holds the most promise other putative targets of stimulation may depend upon seizure localization and also include subthalamic nucleus caudate hippocampus cerebellum hypothalamus centromedian [...]

The children became also more responsive to social and educational interventions. Nevertheless it remains palliative procedure and preoperative evaluation should focus definitively excluding resectable amenable to curative therapies. Injury to any portion of the memory circuit prevalent along midline cortical and subcortical structures can result some form infarcts be present postoperatively if venous drainage is compromised via sagittal sinus directly indirectly essential draining vein during transcallosal approach. contrast eccentricity may be expected to affect ipsilateral projection more than crosscuing subcallosal transfer. Early callosotomy was associated with milder postoperative sequelae and fewer disconnection deficits children who underwent before puberty experienced if any of the typical seen in adult patients Bogen whereas older showed syndrome [...]

Historically the literature has reported postoperative seizure rates following transcortical approach Kobayashi et . However the longterm seizure freedom rate is probably far lower TellezZenteno et al. Over the past three decades we studied longterm sequelae of procedure in these children .

During the morcellation of tumor and resection off ventricular wall hemostasis should be maintained. The results were ambiguous due to small numbers of trials and low sensitivities signal detection . As would be expected outcome paralleled neurological improved seizure control resulted in greater alertness and attention memory most cases. The absence of disconnection deficits and milder postoperative sequelae following callosotomy these young patients suggest that greater cerebral plasticity immature brain may allow for more extensive adjustment after surgery [...]
