Abstract
INTRODUCTION At present, selective amygdalohippocampectomy (SAH) has become popular in the treatment of drug-resistant mesial temporal lobe epilepsy (TLE). However, there is still an ongoing discussion about the advantages and disadvantages of this approach. METHODS The study included a consecutive series of 43 adult patients with drug-resistant TLE, involving 24 women and 19 men (1.8/1). Surgeries were performed at the Burdenko Neurosurgery Center from 2016 to 2019. To perform subtemporal SAH through the burr hole with the diameter of 14 mm, we used two types of approaches: preauricular, 25 cases, and supra-auricular, 18 cases. The follow-up ranged from 36 to 78 months (median 59 months). One patient died 16 months after surgery (accident). RESULTS By the third year after surgery, Engel I outcome was achieved in 80.9% (34 cases) of cases and Engel II in 4 (9.5%) and Engel III and Engel IV in 4 (9.6%) cases. Among the patients with Engel I outcomes, anticonvulsant therapy was completed in 15 (44.1%), and doses were reduced in 17 (50%) cases. Verbal and delayed verbal memory decreased after surgery in 38.5% and 46.1%, respectively. Verbal memory was mainly affected by preauricular approach in comparison with supra-auricular (p = 0.041). In 15 (51.7%) cases, minimal visual field defects were detected in the upper quadrant. At the same time, visual field defects did not extend into the lower quadrant and inside the 20° of the upper affected quadrant in any case. CONCLUSIONS Burr hole microsurgical subtemporal SAH is an effective surgical procedure for drug-resistant TLE. It involves minimal risks of loss of visual field within the 20° of the upper quadrant. Supra-auricular approach, compared to preauricular, results in a reduction in the incidence of upper quadrant hemianopia and is associated with a lower risk of verbal memory impairment.

[PMID: 31689571 DOI: 10.1016/j.wneu.2019.10.160] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2019] [Revised: 10/24/2019] [Accepted: 10/25/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To describe our series of a minimally invasive technique using a small scalp incision and keyhole craniotomy for the removal of mesial temporal lobe structures through a transcortical approach in patients with medically intractable mesial temporal lobe epilepsy (MTLE). Studies that directly compare the clinical outcomes between minimally invasive and conventional techniques are scarce, and this information is lacking in the literature. METHODS The study enrolled 73 consecutive patients with refractory MTLE and unilateral hippocampal sclerosis; 30 patients were operated on with standard frontotemporal craniotomy between 2010 and 2013 and 43 patients were operated with a minimally invasive craniotomy (nummular craniotomy) between 2014 and 2016. The preoperative evaluation included clinical history, physical examination, video-electroencephalography, neuropsychologic assessment, and magnetic resonance imaging including thin-section coronal sequences. RESULTS There were no deaths in either group. Postoperative complications in the standard frontotemporal craniotomy group included temporal muscle atrophy (n = 4; 13.3%), cerebrospinal fluid leakage (n = 1; 3.3%), and wound infection (n = 1; 3.3%). No complications were observed in the keyhole craniotomy group. There was no between-group difference in postoperative seizure control. The mean Engel class I seizure-free outcome was 90.4% in the standard frontotemporal craniotomy group and 90.7% in the nummular craniotomy group (P > 0.05). Lengths of hospitalization (2.81 vs. 4.37 days, P < 0.001) and operative time (85.79 vs. 142.73 minutes, P < 0.001) were lower in the keyhole than in the standard frontotemporal craniotomy group, respectively. CONCLUSIONS The nummular technique was associated with faster recovery, early hospital discharge, and fewer complications than the standard technique. No differences were observed in postoperative seizure control. Keyhole craniotomy is a safe, easy, and effective treatment option for medically intractable MTLE.
