Temporal lobectomy for intractable epilepsy in patients over age 45 years.
3 Pt 1
Surgical management of uncontrolled focal epilepsy is most commonly carried out in young adults with good results, but there has been some doubt about the effectiveness of cortical resection in older individuals. We assessed the outcome of temporal lobectomy done after age 45 years in 20 patients with intractable epilepsy followed for more than 2 years after surgery. During a mean follow-up of 5 years, six patients (30%) were seizure-free following surgery and seven (35%) had greater than 90% reduction in seizure frequency. This compares with an outcome of 40% seizure-free and 44% with greater than 90% seizure reduction in 68 younger patients aged 17 to 45 years; the differences do not achieve statistical significance. The outcome was better for complex partial seizures than for secondarily generalized seizures. Complications were no greater than in the younger patients. The findings indicate that surgery is an effective treatment alternative for intractable temporal lobe epilepsy in older patients since two of three of these patients will obtain satisfactory seizure control.
