hemispherectomy [hem′′i·sfēr·ek′tə·mē] resection of one hemisphere of the brain, most often performed to treat intractable seizure disorders in children. Although this surgery results in some physical debilitation, such as loss of use of the hand opposite the resected hemisphere and some visual dysfunction, it does not affect cognitive abilities.

While the prognosis for a more complete recovery after a hemispherectomy is clearly better for younger children, a recent report detailing the marked improvement over time in a 14-year-old girl who had this procedure concluded that "the critical age beyond which functional reorganization takes place after a unilateral injury in childhood is not known. His recommendation: take out the entire left half of the brain--a procedure called a hemispherectomy (he-muh-sfir-EK-tuh-mee). He has also refined the techniques for hemispherectomy, a radical brain surgery to stop intractable seizures. |
