Lateralising value of ictal features in partial seizures: effect on postsurgical outcome.

We reviewed the videotapes of 49 consecutive patients with a history of medically refractory temporal lobe epilepsy for the presence and laterality of unilateral hand posturing (UHP), unilateral hand automatism (UHA), non-forced head turning (HT), and post-ictal dysphasia (PID). All of these patients underwent temporal resections with follow-up for more than 2 years after the surgery. We examined the correlation of consistency, frequency, and laterality of each of these signs on the postsurgical outcomes. The distribution of these signs was not significantly different between patients with Engel class 1 versus Engel class 2-4. The consistency and laterality of these signs do not correlate with postsurgical outcomes.
