Introduction: Surgical resection of mesial temporal structures is usually necessary for the treatment of some focal epileptic syndrome, more commonly temporal mesial sclerosis. Our objective is to describe our clinical results of a novel operative technique for treatment of temporal epilepsy.

Methods: To describe a prospective case-series of a single institution, performed by a single surgeon, from 2006 to 2012, a total of 120 patients were submitted to minimally invasive keyhole transtemporal amygdalohippocampectomy.

Results: 55% of patients were male, 85% of patients had a right-sided disease. The first 70 surgeries had a mean surgical time of 2.51 hours, and the last 50 surgeries had a mean surgical time of 1.62 hours. There was 3.3% morbidity. There was 5% of mild temporal muscle atrophy. There wasn’t visual field impairment. In the Engel Outcome Scale at 2-year follow-up, 71% were Class I, 21% Class II, 6% Class III.

Conclusions: This novel technique is feasible, reproducible and with a good to great clinical result.

Patient Care: Describing a simple technique with a great clinical result

Learning Objectives: To describe a novel technique for treatment of temporal epilepsy.
