Area of Science:

Neurosurgery
Epileptology
Medical Imaging

Background:

Insular epilepsy surgery outcomes can be poor due to inadequate monitoring of the epileptic zone.
Precise monitoring and tailored resection are crucial for successful insular epilepsy surgery.

Purpose of the Study:

To precisely monitor the hidden cortex during insular epilepsy surgery.
To evaluate the effectiveness of subpial depth electrodes for monitoring and resection.

Main Methods:

A single-center series of six patients with medically intractable epilepsy underwent insular surgery.
Monitoring methods included strip electrodes, stereotactic depth electrodes, and open direct subpial depth electrode insertion.
Resection extent varied from partial to total insulectomy.

Main Results:

No surgery-related complications occurred with subpial depth electrode insertion.
83.3% of patients achieved Engel class I outcome, with 16.5% in Engel class II.
Total insulectomy was achieved in three patients using open direct subpial depth electrodes without increased morbidity.

Conclusions:

Image-guided insular surgery with subpial depth electrode guidance ensures safe and accurate resection.
This approach leads to optimal outcomes and complete removal of the insular cortex in epilepsy surgery.
