At Istinye University Medical Park Gaziosmanpasa Hospital, Hemispherectomy is performed using advanced epilepsy surgery techniques and multidisciplinary neurological assessment. Established in 2015, the ISO, JCI accredited hospital in Istanbul, Turkey has 197 beds and provides comprehensive pediatric and adult neurosurgical services.

Hemispherectomy may be recommended for carefully selected patients with debilitating epilepsy that does not respond adequately to anti-seizure medications. Before surgery, specialists perform detailed assessments such as video EEG, MRI, neuropsychological testing, and other functional studies to identify the seizure-producing hemisphere and evaluate the expected neurological outcome. During surgery, the abnormal hemisphere is largely removed or functionally disconnected from the rest of the brain. Postoperative rehabilitation may be required to support movement, speech, and other neurological functions.
