Abstract

Purpose: To analyze the localizing and lateralizing value of ictal smile (IS) in childhood epilepsy. Methods: Incidence of IS in 309 videotaped seizures of 114 consecutive patients younger than 12 years with refractory frontal, temporal, or posterior cortex epilepsy were assessed. Results: Among patients with right-sided epileptogenic zone, 12 (21%) of 57 had IS, whereas in patients with left-sided epilepsy, IS occurred only in one patient (1.8%; p <0.01, χ2 test). The incidence of IS was 11%, 3%, and 26% in the frontal, temporal, and posterior cortex subgroups, respectively. Logistic regression revealed that the localization of the epileptogenic region in the posterior cortex (p <0.01), focal cortical dysplasia etiology (p = 0.012), and right-sided lateralization (p = 0.025) were independently associated with the presence of IS. Conclusions: Childhood IS lateralizes to the right hemisphere and localizes more frequently in the posterior cortex epilepsy.
