Postoperative seizure outcome related to pathology and side of resection

Pathology (no. of patients)Class 1A/1B, n (%)Class 1C/1D/2, n (%)Class 3/4, n (%)Significance*
Outcome: (MTS) class 1C/1D vs other outcome—left 10 (10.2%), right 13 (19.1%); p = 0.107. Engel classification of postoperative seizure outcome (reference 7): class 1A/1B = completely seizure free or nondisabling simple partial seizures; class 1C = some disabling seizures but free for at least 2 years; class 1D = generalized seizures with antiepileptic drug withdrawal only; class 2 = rare disabling seizures; class 3 = some improvement; class 4 = no worthwhile improvement.
* Univariate logistic regression analysis.
† Two patients died in the immediate postoperative period.
MTS = mesial temporal sclerosis; NS = nonspecific.
