Abstract:
Objective: To assess the surgical techniques and surgical outcomes of temporoparietooccipital and
parietooccipital disconnection. Methods: The authors conducted a retrospective review of clinical,
neuropsychological, EEG, imaging data in 16 patients with intractable epilepsy who underwent
temporoparietooccipital and parietooccipital disconnection between April 2008 and October 2011.
Of the 16 cases, 12 were males and 4 were females. The age of seizure onset was from 0.1 to 27
years (average 6.6) and disease duration of 0.1 to 18 years (average 7.5). The surgery was performed
between the age of 3 and 37 years (average 14.1). Nine patients underwent temporoparietooccipital
disconnection, 5 patients parietooccipital disconnection and 2 patient parietooccipital disconnection
and temporal lobotomy. Results: After a mean follow-up of 1.6 years (range 0.5–3.9 years), 13 patients
(81%) were seizure free, 1 patient had Engel Class II seizure outcome and 2 patient had Engel class
III outcome. Two patients exhibited severe brain swelling and one patients had second resective
operation with good recovery. None of the patients developed new motor defi cits postoperatively and
there was no mortality.
Conclusion: Temporoparietooccipital and parietooccipital is a safety and effective epilepsy surgery
procedure for patients with epileptic zone localization to the posterior quadrant on one side. The results
of surgical disconnection for posterior quadrantic epilepsy have yielded excellent seizure outcomes
in 81% of the patients, with no mortality or major morbidity.
