Mesial temporal lobe epilepsy (mTLE) is the most common form of drug-resistant focal epilepsy, affecting approximately one-third of epilepsy patients. This condition is characterized by recurrent seizures that do not respond to standard antiepileptic treatments, significantly impacting patients' quality of life.

The standard treatment for drug-resistant cases remains anterior temporal lobectomy (ATL), a surgical procedure that removes the brain region responsible for seizures. This approach has demonstrated high efficacy, with a significant rate of seizure freedom. However, it is associated with post-operative risks, including neurocognitive impairments, memory deficits, and risks of infections or hemorrhages. Additionally, not all patients are eligible for this surgery due to the location of epileptic foci or the presence of comorbidities.


Given these limitations, less invasive alternatives have emerged, including laser interstitial thermal therapy (LITT), radiofrequency ablation (RFA), and stereotactic radiosurgery (SRS). These techniques aim to selectively destroy epileptogenic foci while minimizing damage to healthy brain tissue. LITT, in particular, uses an MRI-guided laser fiber to generate targeted hyperthermia, inducing cellular necrosis and reducing epileptic activity. Compared to conventional surgery, this minimally invasive approach offers reduced recovery time and fewer post-operative complications while showing promising efficacy in seizure control.


This study explores the efficacy and safety of LITT, RFA, and SRS in the treatment of drug-resistant temporal epilepsy.

LITT: A promising alternative?

A total of 42 studies including 1,675 patients with mTLE were analyzed. Among them, 1,303 underwent LITT, 188 underwent RFA, and 184 received SRS. The effectiveness of these techniques was assessed based on the following outcome variables: seizure freedom rate (Engel classification), major complication rate, and reoperation rate.

The results indicate that LITT stands out in terms of efficacy and safety compared to other minimally invasive techniques. In terms of seizure control, LITT achieved the highest seizure freedom rate (55.0%), followed closely by SRS (53.8%) and RFA (46.3%). Patients with hippocampal sclerosis responded particularly well to LITT, suggesting an optimized potential for this subgroup.


Regarding safety, LITT had the lowest major complication rate (2.3%), significantly lower than SRS (14.3%) and RFA (3.9%). The reoperation rate followed a similar trend: 14.3% for LITT, compared to 15.4% for SRS and 28.6% for RFA, confirming the long-term effectiveness of LITT and its advantage in reducing the need for additional surgical interventions.


These findings position LITT as an effective and safe alternative to existing minimally invasive techniques, offering a viable option for patients seeking less invasive solutions than conventional surgery.

Towards a minimally Invasive revolution in epilepsy treatment

mTLE is one of the most common forms of drug-resistant focal epilepsy. When medications fail, conventional surgery, particularly ATL, is often the recommended approach. However, this invasive method carries post-operative risks and may lead to cognitive or neurological deficits. In response to these challenges, minimally invasive techniques such as LITT are emerging as promising alternatives.

This study aimed to evaluate the efficacy and safety of LITT compared to other minimally invasive techniques, such as RFA and SRS. By analyzing seizure control rates, post-operative complications, and the need for reoperation, the study sought to better position LITT in the therapeutic arsenal for mTLE.


The results show that LITT provides effective seizure control, with a competitive seizure freedom rate compared to other minimally invasive approaches. Its safety profile is also favorable, with lower complication rates and reduced need for reintervention. These factors make LITT an effective and less invasive alternative to conventional surgery, especially for patients looking to avoid major surgical procedures.


However, certain limitations must be considered. The lack of direct comparative studies between LITT and anterior temporal lobectomy limits the scope of the conclusions, especially since the current data primarily come from retrospective studies. Prospective and randomized clinical trials will be necessary to confirm these findings and better define the indications for LITT. The integration of technologies such as intraoperative MRI and Artificial Intelligence to analyze therapeutic responses could further enhance its effectiveness.
If these advancements materialize, LITT could become a preferred alternative for patients with drug-resistant mTLE, offering a more targeted and less invasive treatment option.
