AbstractEpilepsy surgery offers a vital treatment option for drug-resistant mesial temporal lobe epilepsy, with temporal lobe resection (TLR) and magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) being fundamental interventions. This meta-analysis specifically examines seizure outcomes at extended follow-up periods exceeding 24 months, visual field deficits as measured by perimetry, and complication rates both overall and categorized based on duration as minor (transient <6 months) or major (persistent >6 months) to inform clinical decision-making. For seizure freedom, TLR was superior, with 72.5% [65.6%, 78.5%] of patients achieving postoperative seizure freedom compared to 57.1% [51.2%, 62.7%] for MRgLITT (P value <0.01). Visual field deficits were observed in 79.4% [59.5%, 91.0%] of TLR patients and 49.8% [23.6%, 76.0%] of MRgLITT patients, a difference not reaching statistical significance (P value: 0.08). Overall complication rates were 11.4% [7.4%, 17.2%] for TLR and 6.5% [3.3%, 12.3%] for MRgLITT (P value 0.15). Major complications occurred in 2.0% [1.1%, 3.09%] of TLR cases and 2.7% [1.4%, 5.2%] of MRgLITT cases (P value 0.54), while minor complications were significantly more frequent with TLR at 9.9% [6.4%, 15.0%] versus MRgLITT's 4.1% [1.9%, 8.4%] (P value 0.04). MRgLITT had a more favorable outcome regarding confrontation naming, while more studies are needed regarding verbal memory to be able to draw firm conclusions. TLR provides superior seizure freedom but comes with an increased risk of transient complications. Although there was no statistical significance in visual field deficits, the trend suggests a higher frequency with TLR. The study's extensive data analysis, including rigorous sensitivity checks, ensures the robustness of these conclusions, reflecting a comprehensive analysis of the available data at this time point.Copyright © 2024 The Authors.
