[Diagnosis and surgical treatment of temporal lobe epilepsy]
1Department of Neurosurgery, Huashan Hospital, Shanghai Medical University, Shanghai 200040, China.
Objective:
To discuss the diagnosis and surgical treatment of temporal lobe epilepsy.
Methods:
From 1995 to 1998, 30 patients with intractable mesial temporal lobe epilepsy were identified by EEG and MR. Among them, 15 patients underwent anterior temporal lobectomy, while another 15 patients accepted selective amygdalahippocampectomy. The results of operation and follow-up were analyzed.
Results:
As to seizure outcome, all patients were benefited from surgery. Surgical result was satisfactory in 18 patients, notable in 11, and good in 1. There was no complication.
Conclusions:
MR is beneficial for the localization of epileptic foci. Operation is an effective way for the treatment of temporal lobe epilepsy. Selective amygdalohippocampus is the first choice for medial temporal lobe epilepsy. Transzygmatic-temporal lobe base approach improves the safety of operation.
Insights
Surgery effectively treats intractable temporal lobe epilepsy. Selective amygdalohippocampus removal is recommended for mesial temporal lobe epilepsy, offering safe and beneficial outcomes.
Area of Science:
- Neurosurgery
- Neurology
- Epileptology
Context:
- Intractable mesial temporal lobe epilepsy presents significant treatment challenges.
- Accurate localization of epileptic foci is crucial for surgical planning.
- Previous surgical interventions have varying success rates.
Purpose:
- To evaluate the diagnostic utility of Magnetic Resonance (MR) imaging in localizing epileptic foci.
- To assess the efficacy and safety of anterior temporal lobectomy versus selective amygdalohippocampectomy for intractable mesial temporal lobe epilepsy.
- To analyze surgical outcomes and complications in patients undergoing epilepsy surgery.
Summary:
- Thirty patients with intractable mesial temporal lobe epilepsy underwent either anterior temporal lobectomy (15 patients) or selective amygdalohippocampectomy (15 patients) between 1995 and 1998.
- All patients experienced seizure reduction post-surgery, with satisfactory results in 18, notable in 11, and good in 1.
- Magnetic Resonance imaging proved beneficial for identifying epileptic foci, and the transzygmatic-temporal lobe base approach enhanced surgical safety, with no reported complications.
Impact:
- Surgical intervention is an effective treatment modality for temporal lobe epilepsy.
- Selective amygdalohippocampectomy is identified as the preferred surgical approach for mesial temporal lobe epilepsy.
- Advanced imaging and surgical techniques improve patient outcomes and safety in epilepsy surgery.
