Temporal lobotomy in the surgical management of epilepsy: technical report.

Objective: To describe the technique of temporal lobotomy and demonstrate that it may produce results equivalent to anterior temporal lobectomy in the control of drug-resistant complex partial seizures of anterior temporal lobe origin.

Methods: Patient selection and evaluation was similar to that for other patients undergoing anterior temporal lobectomy, with the exception that the 10 selected patients all demonstrated extensive lobar or hemispheral atrophy on magnetic resonance imaging or computed tomographic scans. The lobotomy technique involved posterior and superior disconnection, each of which was broken down into lateral and mesial components.

Results: At last follow-up, seven patients were seizure-free, one had rare seizures, and two had a less than 90% decrease in seizures. These outcomes are similar to those in our overall temporal lobectomy series. One patient who underwent left-sided temporal lobotomy had a speech fluency deficit postoperatively.

Conclusion: Temporal lobotomy seems to be an effective disconnective procedure in the treatment of drug-resistant temporal lobe epilepsy. Larger series will be needed to better define its role in the management of this condition.
