Temporal Lobectomy & Resective Epilepsy Surgery
Temporal lobectomy and other resective epilepsy surgeries remove carefully mapped seizure-causing tissue for selected patients with drug-resistant focal epilepsy.
Epilepsy surgery pathway
From evaluation to long-term seizure care
Evaluation
Review history, imaging, EEG results, and medication response.
SEEG and mapping
Use video-EEG, imaging, and sEEG when needed to localize where seizures begin, how they spread, and what functions are nearby.
Decision
Choose resection, ablation, neuromodulation, further mapping, or non-surgical care.
Treatment
Carry out the selected procedure with a plan for safety, recovery, and seizure goals.
Follow-up
Track seizure control, medications, recovery, mood, and device settings when needed.
Precision mapping
MRI, video-EEG, neuropsychology, and sEEG when deeper localization is needed.
Tailored treatment
Resection, laser ablation, or neuromodulation selected around seizure anatomy and goals.
Long-term planning
Device programming, follow-up, and medication strategy coordinated with the epilepsy team.
Overview
Resective epilepsy surgery is designed to remove the brain tissue where seizures begin, when that area can be identified and treated safely. Temporal lobectomy is one of the best-known forms of resective epilepsy surgery and may be considered for selected patients with drug-resistant temporal lobe epilepsy.
Who it is for
Resective surgery may be appropriate when seizures continue despite medication and testing shows a clear seizure onset zone. Evaluation often includes MRI, video-EEG monitoring, neuropsychological testing, and sometimes sEEG to confirm the target and understand nearby functions.
The best candidates have a seizure onset zone that is both well localized and safely treatable. When the target is close to language, memory, vision, movement, or sensation, additional mapping may be needed before a surgical plan is finalized.
Types of resective surgery
- Temporal lobectomy for selected temporal lobe epilepsy
- Lesionectomy to remove a seizure-causing lesion
- Focal cortical resection for a mapped seizure onset zone
- Disconnective procedures when isolating seizure spread is safer than removal
How surgery is planned
Resective epilepsy surgery is planned around two goals: remove or disconnect the tissue necessary to control seizures, and protect the brain functions the patient depends on. Planning may include image guidance, functional mapping, language or memory testing, and in selected cases awake testing or intraoperative recordings.
During an open resection, a craniotomy provides access to the target region. The bone is replaced at the end of the operation. Some patients spend time in a higher-acuity unit after surgery before moving to a regular hospital room.
What to expect
The goal is to reduce or stop seizures while protecting critical brain function. Before surgery, the epilepsy team reviews the expected benefit, possible risks, recovery, and alternatives such as laser ablation or neuromodulation.
Recovery depends on the procedure and the patient’s baseline health. Some patients have headaches, fatigue, scalp swelling, temporary mood changes, or short-term cognitive changes during recovery. Anti-seizure medication is usually continued at first, even when surgery is successful, and later medication decisions are made with the epilepsy team.
Risks
Risks vary by target and operation. They may include infection, bleeding, stroke, seizures, neurologic weakness, language or memory change, visual field change, mood changes, wound problems, or the need for additional treatment. These risks are reviewed in the context of the expected seizure benefit.
Dr. Barone’s approach
Dr. Barone uses a careful mapping-first approach to determine whether resective surgery is appropriate, and to compare it with less invasive or device-based options including LITT, RNS, VNS, and DBS.
Frequently asked questions
What is temporal lobectomy? +
Temporal lobectomy is an epilepsy surgery that removes selected seizure-causing tissue from the temporal lobe after careful testing confirms the seizure source and safety of treatment.
Who may be a candidate for resective epilepsy surgery? +
Candidates typically have drug-resistant focal epilepsy with a seizure onset zone that can be clearly identified and treated without unacceptable risk to language, memory, movement, or other critical functions.
Is resective surgery the same for every patient? +
No. The operation is tailored to the seizure focus, brain anatomy, test results, and functional risks. Some patients need temporal lobectomy, while others may need a smaller lesionectomy, corticectomy, or disconnective procedure.
