Temporal Lobectomy is the most common performed epilepsy surgery. Specialized surgical centers infrequently perform temporal lobectomies on patients 60 years of age or older. We reviewed our experience on patients in this age group who underwent a temporal lobectomy at our Comprehensive Epilepsy Program., We reviewed our surgery database and identified patients who underwent a temporal lobectomy for intractable seizures at the age of 60 years or older. All patients underwent a comprehensive presurgical evaluation, including EEG-video monitoring, MRI , SPECT or PET, neuropsychologicla testing, and Wada test. Post surgical outcome was measured using Engel classification. Follow up ranged from 5 months up to 20 months., Over a 5 year period, 7 patients 60 years or older underwent a temporal lobectomy at our Epilepsy Center. This represents less than 5% of resective epilepsy surgeries performed. Patient[apos]s ages ranged from 60 to 76 years of age (mean 63.4 years). Duration of epilepsy ranged from 1 year to 53 years (mean 34.8 years ). Etiology was mesiotemporal sclerosis in 4 patients and unclear in 3. Invasive EEG was performed in 1 patient. Post-surgical outcome was class I in 4 patients, class II in 2 patient. No patients fell into Class III or Class IV. One patient developed psychogenic seizures after surgery., Temporal lobectomies are rarely performed after the age of 60, but should be considered and seem so have a comparable outcome to that of younger patients.,
