I would like to know can temporal resection surgery cure petit mal epilepsy.

At least partially..: The focus must first be localized by imaging and/or electrodiagnostic study,and, if localized, must be surgically approachable. If so, and there are no post-surgical complications (e.g. infection, excessive scarring) there can be a 70-90% success rate.Hospital stay is usually no more than a week and complete healing a few months. You MAY still need to be on some kind of medication in low dose

No: Petit mal is a generalized epilepsy usually seen in children. It responds to Ethosuccamide or Depakote. It resolves on its own by age 14 in virtually all boys and most girls. Perhaps you are thinking of Complex Partial Epilepsy which sometimes can be treated with anterior temporal surgery (if the seizure focus is in that anterior temporal lobe)
