Comparison of seizure outcomes and safety between anterior temporal lobotomy and lobectomy in patients with temporal lobe epilepsy.

ABSTRACT

Objectives: To compare the efficacy and safety of anterior temporal lobotomy (ATLo) and anterior temporal lobectomy (ATLe) in drug-resistant temporal lobe epilepsy.Methods: Patients diagnosed with pharmacoresistant temporal lobe epilepsy who underwent anterior temporal lobotomy (ATLo) or anterior temporal lobectomy (ATLe) performed by a single surgeon were retrospectively included. Every patient was followed up annually after surgery. The postoperative seizure outcome evaluation was based on the Engel and ILAE classifications. We compared postoperative complications and 2-year follow-up seizure outcomes between the ATLo group and the ATL group.Results: A total of 42 individuals (21 ATLo and 20 ATLe) were included. At the two-year follow-up, more patients in the ATLo group than the ATLe group had reached Engel class I (20 versus 14) and ILAE I (19 versus 13). However, these differences were not significant. One patient in the ATLo group had intraparenchymal hematoma and fully recovered. The two groups had similar incidences of other short-term complications, and no patients died or had any permanent complications.Discussion: ATLo is not inferior to ATLe for patients with drug-resistant temporal epilepsy. There was no significant difference in seizure outcomes or the rate of postoperative complications between the two groups. A large sample randomized control study is needed.
