AIMS: To analyse the long-term outcome of patients who underwent temporal lobe resection for intractable temporal lobe epilepsy at Auckland Hospital.
METHODS: We performed a retrospective analysis of 176 patients who underwent temporal lobe resection at Auckland Hospital, New Zealand between 1987 and 2007. We had at least 1 year of follow-up on 174 patients.
RESULTS: Overall 98/174 (56%) individuals were seizure-free at 1 year (Engel Class 1) with a marked improvement in quality of life. A further 61/174 (35%) had rare seizures or had significant improvement in seizure frequency (Engel Classes II or III). At last follow up (mean 4.3 years) 95/174 (55%) were seizure-free (Engel Class 1). Hippocampal sclerosis was the pathological finding in 129 patients. Surgical complications included 2 (1.1%) deaths, while 6 (3.4%) patients had symptomatic visual field defects, and 8 (4.5%) had other permanent neurological problems. A further 18 (10.3%) patients had temporary complications including infection, pulmonary embolus, and aseptic meningitis. New psychological symptoms occurred during the first year after surgery in 52% of 114 patients for whom we had detailed psychiatric assessments.
CONCLUSION: Temporal lobe resection is effective in controlling medically intractable seizures, but there are potentially serious complications that need to be considered when counselling patients for such a procedure.
