Abstract

Introduction: The aim of the study was to assess the difference in clinical characteristics and postsurgical outcomes between children and adults who have undergone temporal lobectomy (TL). Materials and methods: We retrospectively reviewed the medical records of 52 patients who had undergone TL between 2006 and 2008. Nineteen patients were classified as children (≤18 years old), and 33 patients were classified as adults (>18 years old) according to the age when TL had been performed. Results: Twelve of 19 (63.2%) children and 24 of 33 (72.7%) adults became seizure free. Rapid secondary generalization such as generalized tonic or tonic-clonic seizures showed a tendency to be more prominent in children (four of 19, 21.1%) than in adults (three of 33, 9.1%). Patients in childhood had significantly more multifocal discharges on interictal electroencephalography (EEG) (42.1%) compared to adults (15.2%, p=0.014). The mean extent of surgical excision was 5.0 cm in children and 4.1 cm in adults (p=0.001). The incidence of hippocampal sclerosis, the most common pathologic finding in the two groups, was 57.9% (11 of 19) in children and 78.8% (26 of 33) in adults. Malformations of cortical development were significantly more frequent in children (nine of 19, 47.4%) than in adults (seven of 33, 21.2%). Dual pathology was found in 31.6% of children and in 12.1% of adults. The intelligence quotient and memory quotient values in children with temporal lobe resection remained nearly steady during follow-up period without significant decline. Conclusion: Patients undergoing TL during childhood compared to during adulthood had distinctively different interictal EEG, resectional extents, and pathologic findings.
