Abstract
OBJECT: The authors propose that anterior callosotomy -- thought to have some advantages over total callosotomy -- is not superior to total callosotomy for prevention of seizure propagation or other complications.
METHODS: The study comprised 34 patients in whom generalized epilepsy syndrome or frontal lobe seizures with a secondary generalization were diagnosed. Preoperatively, all patients suffered from disabling drop attacks or intense head-drop seizures, and some patients also experienced other types of seizures. The male/female ratio was 22:12, and patients ranged in age between 1 to 19 years (mean 8.7 years). The follow-up period ranged from 1.08 to 5.0 years (mean 2.58 years). Seizure outcome, parental assessment of daily function, and parental satisfaction with the outcome was assessed postoperatively.
RESULTS: After undergoing 1-stage total callosotomy, drop attacks disappeared completely in 25 patients during the follow-up period, and in 6 patients the frequency of drop attacks decreased to < 10% of baseline. With regard to other types of seizures, seizures resolved completely in 12 patients, and in another 18 seizure frequency decreased. Two patients experienced a transient disconnection syndrome for 2 and 4 weeks. One patient experienced ataxic hemiparesis for 3 weeks before it completely abated. The overall daily function of the patients improved, and all parents were satisfied with the surgical outcome.
CONCLUSIONS: For pediatric generalized epilepsy syndrome, 1-stage total callosotomy will be the first choice in treatment for controlling generalized seizures.
